Ancient Six Healing Sounds Qigong

Six Healing Sounds Qigong: sound, breath and movement, from shadow emotion to light virtue.

Six traditional sounds, a tone for each, and music that carries the emotional journey.

A seven-day immersion inspired by Liu Zi Jue, the traditional Six Healing Sounds, for QiGong and TaiChi teachers and therapists who want to deepen their own practice and bring sound and music into their teaching.
The first immersion took place at the Leqita Summer Academy in 2025, and the second there in 2026. The next immersion is at the Leqita Summer Academy in July 2027, with more details to follow.

Who it is for

QiGong and TaiChi teachers, therapists, and committed practitioners who want to work with sound as a living part of Qigong.

What the seven days contain

One organ, one sound and one emotion each day, with movement, breath, voice, visualisation and curated instrumental music. By Day 6 the full form comes together; Day 7 is integration.

Who shares it

I'm Raymond Hackland, and I practised for many years with Bob Lowey of Qigongtauk and the 7 Stars School of Taijiquan. The form I share in the immersion is my own.

The Practice

The Six Healing Sounds: six sounds, six organs, one breath

Each sound is linked to an organ and its emotion. Through gentle movement, conscious breathing, vocal resonance and visualisation, the practice cultivates balance, vitality and inner awareness.

Lungs · SSSSS · Tuning 741 Hz
Metal and the colour white: the sound supports the turn from grief toward courage.

Water drop icon for the kidneys and the CHOOO healing sound

Kidneys · CHOOO · Tuning 396 Hz
Water and deep blue: the sound grounds fear and cultivates wisdom.

Leaf icon for the liver and the SHHHH healing sound

Liver · SHHHH · Tuning 528 Hz
Wood and green: the sound releases the heat of anger and makes space for kindness.

Flame icon for the heart and the HAAAA healing sound

Heart · HAAAA · Tuning 639 Hz
Fire and red: the sound softens impatience and opens toward joy.

Sun over mountains icon for the spleen and the WHOOO healing sound

Spleen · WHOOO · Tuning 852 Hz
Earth and gold: the sound gathers worry back into centeredness.

Three linked circles icon for the Triple Burner and the HEEE healing sound

Triple Burner · HEEE · Tuning 963 Hz
The San Jiao joins the upper, middle and lower body, bringing what feels fragmented into harmony.

As a musician, I give each sound its own tuning. After the traditional form, we practise the sound again with a tone set to that pitch. I take the pitches from the modern Solfeggio set because I like how they sound together. The songs that follow are chosen for their emotional journey, from grief to courage for the lungs, not for their pitch. Choosing the tuning and the songs is part of my method, the way a composer chooses a key: an invitation to resonance, not a health claim.

Immersions

The Six Healing Sounds: a seven-day immersion

Each day of my immersions is one organ: the sound and its movement, then its tone, then lying down inside a music journey I've chosen, then the form again.

Seven sessions of 90 minutes. Each day focuses on one organ, one sound and one emotion, and each new day revisits the sounds already learned. By Day 6 the complete form is practised in sequence; Day 7 is given to integration and a practice circle. The Six Healing Sounds (Liu Zi Jue) are among the best-known qigong practices; this practice is inspired by and connected to them, not a replacement for them. The order of the days follows my own sequence, which differs from the standard 2003 Health Qigong form (liver, heart, spleen, lungs, kidneys, triple burner).

Each session moves through

· Gentle warm-up and grounding
· Breath awareness and mindfulness
· Organ-specific Qigong movement and sound
· Tone and music: a tone set to each sound's tuning, then songs chosen for each organ's emotional journey
· Reflection, embodiment cues and Neigong principles
· Group sharing, questions and journaling

🟣 Lived experience. On lungs day, after the music, I don't tell people what to expect. I simply ask: "What did you notice?" Most participants have told me they were moved, sometimes deeply, and some said something heavy around grief had loosened. Many described their chest as feeling fuller, more spacious and lighter as they breathed. I share this because it's what people told me they felt, in my immersions, in that moment. It isn't a study, it isn't a result I promise, and everyone's experience is different. It's not medical advice or treatment.

The arc of the week

· Day 1 Lungs, grief to courage
· Day 2 Kidneys, fear to wisdom
· Day 3 Liver, anger to kindness
· Day 4 Heart, impatience to joy
· Day 5 Spleen, worry to centeredness
· Day 6 Triple Burner, fragmented to harmony, and the full form
· Day 7 Integration and practice circle

What participants leave with

· The full Six Healing Sounds sequence, and the confidence to practise it on their own
· A clearer awareness of their emotional and energetic patterns
· Sound and breath as tools for daily self-care, including a 10–15 minute evening sound ritual
· A participant handout covering organ, element, colour, sound, acupuncture points, visualisation and a music playlist for each day
· A reflection journal template and, for teachers, session-by-session teaching notes

The first immersion took place at the Leqita Summer Academy in 2025, and the second there in 2026. Next immersion: Leqita Summer Academy, July 2027, more details to follow. Join the mailing list to hear first when booking opens.

About me

A living tradition, practised with care

Liu Zi Jue, the "Six Character Formula", is a breathing and sound practice rooted in Classical Chinese Medicine and Taoist philosophy. It goes back to the Dao Yin practices of Taoist monks, hermits and scholars. Breathing out on sounds is already mentioned in Daoist writings more than 2,000 years old. The six sounds were first written down between the 6th and 8th centuries. In 2003 China's General Administration of Sport issued a standardised "Health Qigong" version, compiled by its Health Qigong Management Center and now promoted by the Chinese Health Qigong Association (founded 2004). Today it is taught widely in China and around the world.

I approach the form as a practice of resonance. The traditional movements and sounds are joined with breathwork, Neigong principles and sequenced instrumental music, so that each sound is felt as a passage from shadow emotion toward light virtue.

Connected, not a replacement. This work draws on traditional Liu Zi Jue as its reference and inspiration. It is a personal, music-assisted interpretation, not a replacement for the classical form or for study with a qualified teacher of the tradition.

I'm a musician who shares qigong: I choose the tone and the songs so you can hear each organ's emotional change, and then we return to the form.

Musician. I'm a musician first, and a curious one. I trained in piano from an early age through Trinity College of Music, London, with my examinations taken in Glasgow. As an adult I taught myself guitar, songwriting, singing and mouth harmonica, and went on to have some commercial success as a solo artist, with chart and radio play and small European tours.

Years on stage taught me something I couldn't let go of: live sound does something to a room. Resonance and vibration move through an audience in ways you can feel before you can explain them. When I met the Six Healing Sounds, an ancient practice built on breath and sound, it felt like finding the other half of the experiment.

So that's what Resonance Heritage Qi is: my sound lab. I use Qigong as the bridge, and I pair each of the six sounds with carefully chosen music and a tuning of its own, exploring how tone, rhythm and pitch shape the way the practice feels. Part tradition, part curiosity, and always a little bit mad.

Lineage. I studied with Bob Lowey, Founder and Director of Qigongtauk (Qigong Teachers Association United Kingdom) and Founder and Principal Tutor of the 7 Stars School of Taijiquan (established 1985). Bob has been involved with Qigong and Chinese martial arts since the early 1970s and gained his Instructorship in 1979. In China he became an initiate of Grandmaster You Xuande (Wudang Pai), with further studies under the late Professor Zhang Guangde (Beijing), and in the UK with Sifu Gordon Faulkner.

As my teacher for many years, in Scotland and Germany, Bob has taught me several Qigong forms, including The Poem (形体诗韵, Xíngtǐ Shīyùn), Daoyin Yangsheng Gong (导引养生功, Dǎoyǐn Yǎngshēng Gōng), Daoyin Baojian Gong (导引保健功, Dǎoyǐn Bǎojiàn Gōng), the Tai Chi 13 Postures (十三势, Shísān Shì), the Five Animal Frolics (五禽戏, Wǔqín Xì), Muscle and Bone (舒筋壮骨功, Shūjīn Zhuànggǔ Gōng), the Shaolin Yi Jin Jing or Sinew-Changing Classic (易筋经, Yìjīn Jīng), the Wudang 18 Postures (武当十八势, Wǔdāng Shíbā Shì), Wu Xin Xing or the Five Elements form (五行, Wǔxíng), Stomach and Spleen Qigong (和胃健脾功, Héwèi Jiànpí Gōng) and the Heart form (舒心平血功, Shūxīn Píngxuè Gōng). He has also taught me classical Chinese weapon forms, including the Yang Tai Chi Sabre (杨式太极刀, Yángshì Tàijí Dāo) and the Cane Form. The Six Healing Sounds form I share is my own; it doesn't come from Bob.

I don't currently give regular classes. My focus now is my own practice and development, and I'm preparing for a study trip to Wudang in 2027.

Raymond Hackland, musician and qigong practitioner

What this work is: my own Qigong practice of movement, breath, voice and visualisation, rooted in the traditional Liu Zi Jue, offered for self-awareness, personal cultivation and professional enrichment. It is a way to support inner balance and to bring sound into your own teaching.

What it is not: it is not medical treatment and makes no therapeutic promises. It does not replace diagnosis or care from a qualified health professional. Every movement stays within a comfortable range.

Forms

The Forms

These are the traditional forms I studied over many years with Bob Lowey, in Scotland and Germany. They belong to a wider heritage of Daoyin, Qigong and Taijiquan, and they inform how I move, breathe and listen. They are related to my Six Healing Sounds work but separate from it: what follows describes the forms themselves, not the immersion.

The Poem (Xingti Shiyun · the Daoyin Poem)
The Poem is a twenty-movement form compiled by Professor Zhang Guangde from exercises in his Daoyin Yangsheng Gong system. It is also known as the "Song" of Daoyin Yangsheng Gong. Zhang composed a poem to accompany the movements, and the form is performed to music. The movement names carry images from Chinese culture: Rise at Cockcrow for Sword Practice, Picking Stars from the Sky, Moon Goddess Extends Sleeve, Spirit Turtle Takes Qi, Old Man Flicks His Beard.In an interview, Zhang described the Song as a demonstration form that presents the character of the whole system, rather than a set aimed at any particular health purpose. Bob Lowey teaches it as a form that develops flexibility, strength, energy and inner calm, sometimes with an introduction to acupressure points. It is best approached as a flowing, expressive summary of the Daoyin Yangsheng Gong way of moving.

Daoyin Baojian Gong (Daoyin for General Health)
Daoyin Baojian Gong ("Daoyin exercise for keeping fit") is a set of eight movements from Professor Zhang Guangde's Daoyin Yangsheng Gong. Zhang, a wushu professor at Beijing Sport University, began developing the system in the mid-1970s during a period of serious illness. He drew on classical Daoyin, Traditional Chinese Medicine theory and his background in wushu and Taijiquan, and named the system in 1984. Beijing Sport University reports that the system received a national sports science award in 1992 and became one of China's first national fitness programme projects in 1996.The form combines slow, circling movements with regulated breathing and focused attention. A hallmark of the system is that movements spiral and rotate and reach out to the fingers and toes. Zhang intended Daoyin Baojian Gong for general health maintenance rather than for any single organ system. It is traditionally said to support overall wellbeing and is often taught as an entry point to the wider system.

Hewei Jianpi Gong (Stomach and Spleen Qigong)
Hewei Jianpi Gong (和胃健脾功, "harmonise the stomach, strengthen the spleen") is the Daoyin Yangsheng Gong routine that Professor Zhang Guangde designed with the digestive system in mind. It is taught in two sets of eight movements. The first set opens with Clashing the Teeth and Swallowing Saliva and moves through Picking Stars from the Sky, Roc Pressing Its Crop and Tapping Zusanli, closing with White Crane Spreads Its Wings.As in the rest of the system, the movements are slow and spiralling and are coordinated with the breath. Zhang explained that for the digestive forms he emphasised abdominal breathing. In traditional teaching, this movement is said to gently massage the organs and encourage the flow of qi. In Traditional Chinese Medicine the stomach and spleen are associated with the Earth element and with nourishment. The form is traditionally said to support digestive comfort and a settled, centred feeling. It is a practice of self-care, not a treatment.

Stacked stones illustration for Muscle and Bone (Shujin Zhuanggu Gong)

Muscle and Bone (Shujin Zhuanggu Gong) and Yi Jin Jing
I studied two separate forms with a similar focus on the sinews, joints and bones. The first is Shujin Zhuanggu Gong (疏筋壮骨功, "ease the sinews, strengthen the bones"), known in English as "Muscle and Bone": Professor Zhang Guangde's modern Daoyin Yangsheng Gong routine for the musculoskeletal system. Its first set has eight movements, among them Strengthen the Neck, Rhinoceros Looks at the Moon, Crane Rubs Its Knees and Golden Rooster Heralds Daybreak.The second is the classical Yi Jin Jing, the "Sinew-Changing Classic", a different form that is not part of Zhang Guangde's system. It was traditionally attributed to Bodhidharma at the Shaolin Temple, but historians date the text to the seventeenth century. Today it is most often practised as a sequence of twelve movements.Both forms work through the neck, spine, hips and knees with stretching, turning and gentle loading, always paired with the breath, and both are traditionally said to support suppleness and joint mobility. A 2024 meta-analysis of ten trials by Zhang and colleagues found that Yi Jin Jing may improve some measures of strength and functional fitness in older adults. The authors note that the evidence is limited and of low to moderate quality.Source: Zhang X, et al. (2024). Frontiers in Medicine, 11:1441858. PubMed · DOI

Tiger, deer, crane, bear and ape for the Five Animal Frolics (Wu Qin Xi)

Wu Qin Xi (Five Animal Frolics)
Wu Qin Xi, the "Five Animal Frolics", is traditionally credited to Hua Tuo, a renowned physician of the Eastern Han dynasty (25–220 CE). Drawing on the older Daoyin and breathing practices, he is said to have modelled the movements on the tiger, deer, bear, ape and bird. I studied the standardised Health Qigong version, which the Chinese sports authority launched in 2003 as one of four new forms. It has ten movements, two for each animal.The practice moves between the tiger's power, the deer's ease, the bear's weight, the ape's lightness and the bird's balance. It joins bending, stretching and twisting with steady breathing and calm attention. A 2018 systematic review of 28 studies by Guo and colleagues concluded that Wu Qin Xi may support physical and psychological wellbeing in healthy adults and some clinical groups. The same review notes that methodological weaknesses in most of the studies make firm conclusions difficult.Source: Guo Y, et al. (2018). Evidence-Based Complementary and Alternative Medicine, 2018:3235950. PubMed · DOI

Walking stick illustration for the Cane Form

Cane Form (Taiji walking stick)
The cane form I studied is a traditional Taiji walking-stick form whose origins go back to the time of the Boxer Rebellion (1899–1901); it came from China to Taiwan in the 1950s. Bob teaches it within his 7 Stars School of Taijiquan, and he taught it at Leqita in 2025 and 2026 and will teach it there again in 2027. Bob has also taught it beyond the school, for example as a "Tai-Chi walking stick" workshop at an international Taiji meeting in 2001.The walking stick is among the gentlest of Taiji's training implements. A light stick is held and moved with the same principles that guide the empty-hand form: rootedness, relaxation, continuous flow and movement led from the waist. Working with the stick extends attention beyond the hands and asks the whole body to stay connected through its length. Like other Taiji practices, cane work is traditionally valued for cultivating coordination, balance and calm concentration.

Sabre Form (Taiji Dao)
The Taiji sabre (dao, 刀) is a single-edged, curved blade, one of the classical weapons of Taijiquan; I studied the Yang-style sabre. In this tradition, the sabre set is remembered through a thirteen-line poem of seven-character verses recited during practice. The poem is recorded in Dong Yingjie's Tai Chi Boxing Explained (1948) and in the sabre manual Taiji Dao (June 1959), written by Cai Longyun with Fu Zhongwen demonstrating the form, and its lines carry vivid names such as Seven Stars, Mount the Tiger and Jump the Dragon Gate.Compared with the sword, the sabre has a more vigorous character, with wide cuts and turns and decisive changes of direction. These are still carried by Taiji's soft, connected body mechanics. Practice asks for clear intention, alert footwork and an even breath. It is traditionally valued for developing vitality, coordination and focus within the calm of Taiji movement.

The Science of Sound

Resonance Heritage Qi · Breath, sound and wellbeing: what we know and what we don't

Our approach

Resonance Heritage Qi is my personal, music-assisted take on the Six Healing Sounds. It is inspired by and connected to the traditional qigong practice Liu Zi Jue. It does not replace that tradition, and it does not replace study with a teacher of it. The practice brings together breath, gentle movement and voiced sound, with a tuning for each sound that I choose as a musician.

I want you to be able to trust what you read here, so this page keeps three things apart:

What the research shows. Findings from published, peer-reviewed studies, with links so you can read them yourself.
What is tradition. Ideas that have been handed down through qigong and sound practice for generations. They have meaning and value, but they have not been tested scientifically.
What is still unproven. Areas where the studies are small, early or mixed, or where no studies exist yet.

Each card below has one of four labels, the same ones the Knowledge Hub uses:

Well studied: many studies, including systematic reviews or meta-analyses, point the same way, though open questions remain.
Early evidence: promising but limited. The studies are small, few or still preliminary.
Tradition only: rooted in practice and tradition, with little or no scientific evidence.
Speculative: a hypothesis or popular claim that goes beyond, or conflicts with, current evidence.

1. Slow breathing and longer exhalation

Evidence: Well studied

Breathing slowly, at fewer than about ten breaths a minute (often around six), has been studied a lot. A systematic review found that slow breathing in healthy people was linked with higher heart rate variability and with feeling more relaxed, more comfortable and less anxious. In a randomised study, a daily five-minute practice that stresses a long, slow out-breath ("cyclic sighing") improved mood and lowered breathing rate more than mindfulness meditation did over one month. A meta-analysis of trials found that breathwork in general was linked with somewhat lower self-reported stress, but its authors also urged caution and asked for better-designed studies. Whether a longer out-breath adds anything beyond slow breathing itself is less clear: for that part there is only early evidence.

2. Humming and nasal nitric oxide

Evidence: Early evidence

Your sinuses naturally produce a gas called nitric oxide. In a small 2002 study of ten healthy people, nasal nitric oxide was about 15 times higher during humming than during quiet out-breaths. The researchers think the vibrating airflow helps air move between the sinuses and the nose. A follow-up study found that after several hums in a row, levels drop again as the sinuses empty. These are measurements of airflow and gas. They do not show that humming improves health, and the original authors said any possible benefits still need to be studied.

3. Chanting and vocal toning

Evidence: Early evidence

Chanting naturally slows the breath, because each phrase is sung on a long out-breath. In a small study published in the BMJ, 23 healthy adults recited either a yoga mantra or the rosary. Both slowed breathing to about six breaths a minute, and both brought heart and blood-pressure rhythms more in step. A small pilot brain-imaging study of 12 people found reduced activity in some emotion-related brain areas during "OM" chanting, but not during a plain "ssss" sound. These are interesting early findings from small groups. Larger studies are needed.

4. Vagal tone and heart rate variability (HRV)

Evidence: Well studied

Heart rate variability is the natural variation in time between heartbeats. Researchers use it as a measure of "vagal tone", meaning the activity of the vagus nerve, which is part of the body's rest-and-digest system. A meta-analysis of 58 controlled studies found that HRV biofeedback, a guided form of slow, paced breathing, gave small-to-moderate improvements across a range of outcomes, with the largest effects on anxiety, depression and anger. The authors say it may be useful alongside other care and that more research is needed for specific uses. One theoretical model suggests that the controlled breathing in practices like meditation and yoga may explain some of their effects through the vagus nerve, but this is still a hypothesis (Speculative), and popular claims about "toning" the vagus nerve go beyond the evidence.

5. Music, relaxation and stress

Evidence: Well studied

A large meta-analysis of 104 randomised controlled trials, with more than 9,600 participants, found that music interventions were linked with less stress. This held for both body measures, such as heart rate, and for how stressed people said they felt. Results from single studies vary. In one experiment with 60 women, listening to relaxing music before a stress test helped one stress marker (salivary alpha-amylase) return to baseline faster, while the cortisol response was actually highest in the music group, and it did not change how stressed the women felt. Music clearly matters, but how much it helps depends on the person, the music and the situation.

6. Qigong and Liu Zi Jue (Six Healing Sounds) studies

Evidence: Early evidence

Qigong as a whole has a growing body of research. A broad review of 77 randomised trials of qigong and tai chi reported benefits in areas such as balance, physical function, quality of life and mood. Research on Liu Zi Jue itself is smaller and mostly comes from rehabilitation for people with a lung condition (COPD), where a meta-analysis of 14 trials reported improvements in breathlessness, walking distance and quality of life. The authors note risks of bias and call for more research. In a small German study, people reported more vigour and less tension and fatigue after 30 minutes of Liu Zi Jue practice. My music-assisted interpretation has not been studied itself, so these findings are about traditional practice, not a promise for this one.

7. Solfeggio frequencies

Evidence: Speculative

Solfeggio tones, such as 396, 528 and 639 Hz, are part of modern sound-healing tradition, and I use them as tuning choices, because I find them beautiful and helpful for setting a calm, focused mood. To be honest with you, there is little or no scientific evidence that these particular frequencies have special effects on the body. A few small human trials have used 528 Hz music, but always as part of a wider package and never against the same experience at another frequency, so no trial isolates the effect of a Solfeggio frequency. The closest related human study, a small pilot comparing music tuned to 432 Hz with 440 Hz, notes that it found no prior scientific studies to support claims about special tunings and calls for larger trials. Studies in animals, such as zebrafish, cannot tell us what happens in people. Please enjoy the tones as music and tradition, not as treatment.

Retention: until you unsubscribe. Your data is then deleted; only your email address and sign-up records are kept on a suppression list or as proof of consent.

Provider: MailerLite Limited, 88 Harcourt Street, Dublin 2, D02 DK18, Ireland, as processor (data processing agreement under Art. 28 GDPR). According to MailerLite, the data is stored by its sub-processor Google Cloud EMEA Ltd. (Dublin, Ireland) in data centres in Germany and the Netherlands. The free guide (PDF) is provided via MailerLite on Google Cloud Storage; when you download it, your IP address is technically transmitted to these servers.

Contact form: If you use the contact form, the data you enter (name, email address, message) is sent to me by email via Carrd and used only to reply to you. Legal basis: Art. 6(1)(b) GDPR where your message concerns a contract or pre-contractual steps, otherwise Art. 6(1)(f) GDPR (my legitimate interest in answering enquiries). The data is deleted when it is no longer needed.

4. Transfers to third countries

Carrd and its providers AWS and Cloudflare are based in the USA; access from the USA cannot be ruled out for Google and MailerLite's group companies. Transfers to the USA are based on the European Commission's adequacy decision for the EU-US Data Privacy Framework (Art. 45 GDPR) where the recipient is certified (e.g. Google LLC, MailerLite Inc.), and otherwise on EU Standard Contractual Clauses (Art. 46(2)(c) GDPR), which Carrd includes in its data processing agreement.

5. Cookies and scripts

I do not use any analytics or advertising tools. The pages load the MailerLite script (to display the sign-up forms); this transmits your IP address to MailerLite. The host or Cloudflare may set technically necessary cookies to prevent abuse. You can delete or block cookies in your browser settings.

The MailerLite form script stores a random visitor ID (ml_guid) in your browser’s local storage, which is used to run the signup form. Cloudflare may set the short-lived __cf_bm cookie for bot protection.

This site links to external sites (e.g. PubMed); their own privacy policies apply.

6. Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and to withdraw consent at any time with effect for the future (Art. 7(3)). An email to [email protected] is enough.

Right to object (Art. 21 GDPR): Where I process data based on Art. 6(1)(f) GDPR, you can object at any time on grounds relating to your particular situation.

Right to lodge a complaint (Art. 77 GDPR): You can complain to a data protection supervisory authority, in particular in the EU country where you live. The authority responsible for me is: Landesbeauftragte für den Datenschutz Sachsen-Anhalt, Otto-von-Guericke-Straße 34a, 39104 Magdeburg, Germany, [email protected], https://datenschutz.sachsen-anhalt.de

7. Providing your data

Providing your data is voluntary. Without an email address, however, I cannot send you the newsletter, mailing list updates or the guide. No automated decision-making or profiling takes place.
