Meditation music is a commercial category, but the relationship between sustained sound and contemplative practice is older and more specific than any playlist suggests. Composers such as Éliane Radigue and Catherine Christer Hennix arrived at drone through religious training or through study of raga, and practices such as sound-bowl sessions and chanting use steady tones as an object of attention. The scientific literature on these practices exists, but it is small and often limited in design. This article separates three things that tend to get blended: the traditions, the composers, and what peer-reviewed research can and cannot say. Nothing here is medical advice, and no piece of music is presented as a treatment.
Sustained sound as an object of attention
Many contemplative practices use a steady sound as a point of focus: a chanted syllable, a struck bowl whose tone decays slowly, a held instrumental tone. The appeal is practical. A drone offers little melodic or rhythmic change to follow, so attention can settle on small variations in pitch, overtone and volume. That is also the listening method suggested in how to listen to drone music, and it overlaps with the practice of deep listening developed by Pauline Oliveros.
The relationship between drone and Indian classical music, where a continuous tone anchors the performance, is covered in drone in Indian classical music. It matters here because one of the composers discussed below, Catherine Christer Hennix, studied with a Hindustani raga master.
Éliane Radigue: Tibetan Buddhism and slowly changing tones
Radigue is the clearest case of a composer whose practice and religion are intertwined. As Tricycle recounts, a group of French Buddhist practitioners approached her in 1974 after a performance of Adnos I at Mills College and gave her the address of the Kagyu-Dzong center in Paris. She later practiced in the Karma Kagyu lineage and took a three-year retreat away from music. Her teacher, according to the same account, sent her back to composition, and she went on to complete the Adnos trilogy by 1982.
The work most often linked to her religious life is Kyema (1988), the first part of the Trilogie de la Mort. The article reports that it drew on the Bardo Thodol, known in English as the Tibetan Book of the Dead, and that its six sections correspond to six intermediate states, from birth through dream, contemplation, death, bright light and return. The piece was also shaped by the death of her son, Yves Arman, at 34. Listeners who approach Éliane Radigue with an expectation of relaxation may be surprised: the music is slow, but it deals directly with mortality, and its structure follows a text about dying.
Catherine Christer Hennix and just intonation
Hennix reached sustained sound through a different route. Blank Forms, which has published her work, notes that La Monte Young introduced her to the Hindustani raga master Pandit Pran Nath, and she later studied intensively with him. The same page describes The Deontic Miracle, her just-intonation live-electronic ensemble, which performed her compositions alongside works by La Monte Young, Terry Riley and Terry Jennings in a program called Brouwer’s Lattice at the Moderna Museet in Stockholm. The recordings on the album come from rehearsal tapes made during a ten-day Dream Music Festival.
The sources consulted do not frame Hennix’s work as meditation music, so it would be inaccurate to do so here. What can be said is that her ensemble worked in just intonation, as the album’s track notes indicate, and that the project grew out of study with Pran Nath. Catherine Christer Hennix is a useful example of how sustained tone, long duration and study of a Hindustani vocal tradition can overlap in a body of work without any claim of therapeutic purpose.
What the research says about singing bowls
Sound bowls are the most studied form of “sound meditation,” and the evidence is modest. A 2020 systematic review in Complementary Therapies in Medicine searched for studies of any singing-bowl intervention and found only four peer-reviewed studies, two of which used low-level designs. Those studies reported improvements on measures including distress, anxiety, depression and tension, as well as physiological measures. The authors concluded that, with so few studies and a risk of methodological bias, they could not recommend singing-bowl therapies at that stage, while encouraging more robust research.
A frequently cited example is an observational study by Goldsby and colleagues. It involved 62 participants with a mean age of 49.7 years and found that, compared with before the session, participants reported less tension, anger, fatigue and depressed mood afterward. Participants who had never tried the practice showed a larger drop in tension than experienced ones. The design shows why caution is warranted: comparing people with their own ratings from before a pleasant, quiet session cannot separate the effect of the sound from the effects of sitting still, expectation or time away from a screen.
Chanting and the brain: a small pilot
A well-known imaging study looked at chanting rather than listening. In a pilot using functional MRI, 12 healthy volunteers chanted “OM” and the researchers observed reduced activity in limbic regions including the right amygdala, which did not occur during a control task of pronouncing “ssss”. The authors suggested a possible link to vagus nerve stimulation and argued for clinical potential.
The limits are substantial. The sample was twelve people, mostly men, all healthy; the study describes itself as a pilot. Chanting is an active vocal practice, not passive listening to recorded drone, so the findings cannot be applied directly to ambient or drone albums. A later analysis by the same group on the same twelve participants reported reduced outputs from several regions toward the amygdala during chanting, and that work likewise raises the possibility of treatment for depression only as a hypothesis.
Meditation music in the context of meditation research
The broader meditation literature supplies a useful benchmark. A 2014 systematic review and meta-analysis in JAMA Internal Medicine included 47 trials with 3,515 participants and found moderate evidence that mindfulness meditation programs improved anxiety, depression and pain, and low evidence for stress and quality of life. It also found no evidence that meditation programs were better than active treatments such as drugs, exercise or other behavioral therapies. Those results concern structured programs, not music, and they apply to clinical populations; they do not show that listening to a drone has the same effect.
Taken together, the evidence supports a restrained statement: some people report feeling calmer after sound-based practices, and small studies are consistent with that report, while larger controlled trials that isolate the sound itself are lacking. Whether a particular drone album helps a particular listener to concentrate or relax is a matter of personal experience. Claims about healing frequencies or brain-wave entrainment from recorded music go well beyond what these sources show. For the specific question of binaural tones, see what research says about binaural beats.
Practical notes for listening
A few conclusions follow from the sources. First, treat the compositions as music with histories: Radigue’s Kyema is tied to a specific text and a specific loss, and that context is part of the work. Second, treat sessions of any kind as optional practices; no study cited here supports using them in place of medical care. Third, duration and attention matter more than the label. The piece on music for sleep takes up a related question, and durational performance shows how artists use long time spans as an artistic material in their own right. Readers who want a historical frame can start with the evolution of drone music from ancient practices to contemporary experimentation.
