What Is Akaar? The Open-Vowel Voice Training Every Singer Starts With

Akaar (open-vowel voice training, singing on the "aa" sound before adding words) is the exercise every singer in this tradition starts with. Practicing melody on a single open vowel strips away lyrics and language so a student can hear tone, breath and pitch clearly, without the mouth shapes of consonants getting in the way. It works for any singer, in any genre, at any starting level.

What is akaar in vocal training?

Akaar comes from the Sanskrit "a-kaar," meaning the form or shape of the vowel "a." In Hindustani classical music (the North Indian classical tradition built on raga and taal) and in the Sufi qawwali (devotional singing built on call-and-response, harmonium and tabla) lineage that Samā teaches from, it names a specific and very old training method: singing a melodic line entirely on an open "aa" vowel, the sound in "father," with no consonants and no words attached.

A student learning a raag (a melodic framework, the scaffolding a Hindustani musician improvises within, sometimes spelled raga in Western usage) will typically sing its ascending and descending phrases on akaar long before ever touching a bandish (a fixed, composed song set within a raga) or a qawwali verse. The vowel is a container. Nothing else is asked of the voice except that it sings the correct notes, cleanly, with a steady breath behind them.

Why does training start on "aa" instead of words?

Words are complicated. Every consonant changes the shape of the mouth, the position of the tongue, the amount of air released, and the resonance of the sound. A "t" stops airflow completely for an instant. An "m" pushes sound through the nose. An "s" hisses air out fast. None of that has anything to do with whether a singer is landing a pitch accurately or supporting a note with steady breath, but all of it gets in the way of hearing those two things clearly.

Akaar removes the noise. An open "aa," sung with a relaxed jaw and an open throat, is the vowel that resonates most freely and requires the least muscular interference to produce. By training on it first, a teacher can hear, immediately and without distraction, whether a student's pitch is accurate, whether the breath is steady, and whether the tone is open or strained. A student gets the same clarity listening back to themselves. This is also, not incidentally, why akaar is used as a warm-up by working singers well outside Hindustani music. Removing language from the equation is a universal way to isolate the raw mechanics of the voice.

What does akaar actually develop in a singer?

Three things, mainly, and they build on each other. First, pitch accuracy: without words to hide behind, a singer hears immediately whether they have landed squarely on a note or are sitting slightly above or below it. Second, breath support: a sustained akaar phrase, especially one that climbs or descends across a wide interval, exposes exactly how well a singer is managing airflow. This is closely linked to habs-e-dam (breath retention, a Sufi and yogic breath discipline), which many students train alongside akaar as part of the same foundational period.

Third, and perhaps most valuable for a working singer, akaar develops tone itself: the actual quality and resonance of the voice, independent of style or language. A singer who has spent real time on akaar tends to have a rounder, more open, more controlled sound across their whole range, because the exercise forces the voice to do its job without any of the compensations that words and habit tend to introduce.

Riyaz (disciplined daily practice) built around akaar is slow work. A student might spend the first months of training doing very little else, singing the same simple ascending and descending patterns on "aa" for twenty or thirty minutes a day. This can feel unglamorous compared to learning an actual song, but it is the floor everything else is built on. Skipping it tends to show up later as pitch problems or strain that are much harder to fix once they are habitual.

How does a beginner practice akaar?

A typical beginner session starts seated, spine straight, often with a tanpura or harmonium drone (a sustained reference pitch, traditionally provided by a tanpura or, in this lineage, frequently the harmonium) sounding the tonic note continuously in the background. The student sings a simple phrase, perhaps just three or five notes of a scale, ascending and then descending, entirely on "aa," matching pitch against the drone as precisely as possible.

From there, a teacher will usually introduce short akaar phrases drawn from a specific raag, gradually widening the range and the complexity of the movement as the student's ear and breath control develop. Some teachers pair this with basic taal (a rhythm cycle that organizes the pacing of both singing and tabla accompaniment) so a student learns to place notes in time as well as in pitch. None of this requires the student to already read music or know any South Asian language. It requires only a willingness to sing a single vowel, slowly and attentively, for longer than feels natural at first.

Does akaar work for singers outside Indian classical and qawwali traditions?

Yes, and this is one of the most practical reasons to learn it. Akaar is not gatekept by genre. A gospel singer working on runs, an R&B vocalist building breath control for long phrases, a worship leader trying to steady their pitch, a hip-hop artist who sings hooks, a kirtan (call-and-response devotional chanting) leader wanting a more open tone: all of them are training the same underlying instrument, and akaar addresses that instrument directly rather than addressing any one genre's stylistic habits.

You do not need to be South Asian, speak Hindi or Urdu, or already sing well to start. The exercise is deliberately stripped down to something universal: pitch, breath, tone. For a fuller foundation in how this fits into overall voice training, the guide to freeing your natural singing voice walks through the broader approach this tradition takes to any singer's instrument, regardless of style.

How does akaar connect to raga and taal later in training?

Once a student has real control singing akaar within a raag's phrases, a teacher begins layering in the raag's characteristic ornaments (the specific melodic bends, slides and grace notes that give each raga its identity) and eventually its associated bandish or composition. Words come last, not first, because by the time they arrive the voice already knows how to move accurately through the melody. Adding language at that point becomes a matter of fitting syllables onto a shape the voice has already learned, rather than trying to learn pitch and words simultaneously.

This sequencing, tone and breath before language, sound before words, is one of the clearest structural features of how this tradition teaches, and it is a large part of why students who train this way tend to develop unusually stable, controlled voices even outside the classical repertoire itself.

Why is akaar usually taught in person?

A recorded akaar exercise can show a student what to do. It cannot tell them, in the moment, that their jaw is clenching, that they are sharp on the fifth note of the phrase, or that they are pushing air rather than supporting it. This kind of correction depends on a teacher listening in real time and adjusting, which is a large part of why this tradition has always passed down through the guru-shishya parampara (the direct, oral master-to-student teaching lineage) rather than through recordings alone.

There is also something to singing akaar in a room with other students that a solo practice session does not replicate. Matching pitch against a drone and against other voices, hearing your own tone against a teacher's model in real time, catching mistakes together: this is training this music was built for, not an afterthought to it.

Where to go next after akaar

Anyone wanting to actually hear and practice akaar rather than just read about it can try a free lesson from the Musical Wisdom masterclass series, which includes foundational voice work of exactly this kind. Singers looking for a full, structured path that carries akaar through into raga, ornament and repertoire will find that built out in the Creative Musical Mastery immersion, which is built specifically for singers coming from any genre, not only Hindustani or Sufi backgrounds.

The Vocal Artistry Library holds a deeper set of lessons on tone, breath and open-vowel work for singers who want to go further on their own schedule. And for singers who want to train akaar and the rest of this foundation in person, in a room with a teacher and other voices, the Voice of the Beloved retreat in Bali is built around exactly that kind of shared, immersive week.

Frequently asked questions

Is akaar only for classical Indian singers? No. Akaar trains pitch, breath and tone, which every singer uses regardless of genre. Gospel, pop, R&B, worship and kirtan singers all benefit from the same exercise.

How long do students practice akaar before moving to words? This varies by teacher and student, but many traditional programs spend weeks to months on akaar before introducing a bandish or full composition, since the tone and breath foundation needs to be solid first.

What is the difference between akaar and just humming? Humming is done with the mouth closed, resonating mostly through the nose. Akaar is sung with an open mouth on the "aa" vowel, which engages a different and more open resonance, closer to how most singing actually sounds.

Do I need a harmonium or tanpura to practice akaar? It helps enormously to have a steady drone note to sing against, since matching pitch accurately is much of the point. A basic harmonium works well for this and is also useful more broadly; see the guide to harmonium training for more on that instrument's role.

Can akaar help with pitch problems? Often, yes. Because words are removed, akaar makes pitch accuracy immediately audible to both student and teacher, which is why it is frequently used specifically to diagnose and correct pitch issues.

Is akaar the same in every raga? The vowel stays the same, but the melodic phrases a student sings on akaar change entirely depending on which raag is being studied, since each raga has its own characteristic movement and ornaments.

Why "aa" and not another vowel? The open "aa" sound requires the least muscular interference to produce and resonates most freely, which is why it was chosen as the training vowel rather than a more closed sound like "ee" or "oo."

Can adults with no singing background start with akaar? Yes. Akaar is often the very first exercise given to a complete beginner precisely because it asks nothing of a student except attention to pitch and breath, no prior skill required.
