What to look for

A Carnatic clarinet is a standard B-flat clarinet: beyond the mouthpiece and reed, it needs no adaptation. Start with the key system. The Boehm system has 17 keys and 6 rings; the Albert, or simple, system keeps more holes under the fingers for sliding pitch, so ask a Carnatic teacher which they play. For bending, choose a medium-soft to medium reed and a medium tip opening.

The body material separates the grades. Student instruments are ABS plastic or hard rubber; professional bodies are African blackwood, dense and resistant to moisture and humidity swings. Check the barrel and the pitch standard: barrel length sets the overall tuning, and some current models are built at A = 442 Hz, so some players carry two barrels for ensemble tuning. Check the pads too: a leak silences or overblows a note and breaks gamaka in that register. Ask us for a quote, or for a clarinet made to order.

Read the clarinet care guide
  • Soak each reed 30 seconds before playing and rotate two or three, as sustained gamaka tires them. Store them flat with a humidity card, since a warped reed makes bending inconsistent.
  • Swab each joint with a silk or microfibre pull-through after playing, as damp softens the wood and can crack the body. Brush the mouthpiece separately.
  • Check the pads for leaks every six months: a leak silences or overblows a note and breaks gamaka in that register. We re-seat or replace single pads. Avoid needless key presses, which wear springs and pads.
  • Blackwood is stable but benefits from bore oil on a pull-through swab once or twice a year against surface drying; some makers advise none on a new clarinet. Never oil tone holes or tenon corks.
  • Grease the tenon corks thinly, as a dry cork tears or sticks and can crack the socket, and replace compressed cork. Store the clarinet disassembled in a padded case and never leave it assembled in damp or cold; temperature swings stress the joints and keys.

Academia KalaSudha

Learn the clarinet with us

All courses

You can learn the Carnatic clarinet with KalaSudha online and in workshops, and beginners start at Foundation level. Foundation builds a stable single-reed embouchure and an even tone in the low and middle registers before any Carnatic technique. Children learn with us as well as adults: ask us about a starting age and about an instrument size for a younger learner.

Clarinettists returning after a long break pick up where they left off. Our courses run in levels, so your teacher reviews where you stand first.

Your route, stage by stage

  1. Embouchure and tone production

    Our courses start beginners here, at KalaSudha's Foundation level. Build a stable single-reed embouchure, the lower lip cushioning the reed; its placement and bite change the reed's stiffness and pitch. Develop a centred, even tone in the chalumeau, then the clarion, at soft and loud levels, before any Carnatic technique.

  2. Register navigation and the twelfth

    Master the register key and the jump at the twelfth, an octave and a fifth, larger than the saxophone's octave. Learn the four registers, chalumeau, throat, clarion and altissimo, and practise the throat-to-clarion move until it sounds even at every dynamic, then carry raga phrases across it.

  3. Embouchure bending for gamaka

    Develop jaw and lip bending for gamaka, with vocal-tract shaping and sliding a finger part-way off an open hole. Start with slow bends below a held note, then oscillation (kampita) and glide (jaru); the cylindrical bore is very sensitive to embouchure change, so build speed slowly.

  4. Carnatic scales, kritis and alapana

    Learn the melakarta scales with gamaka on each note of the raga. Study the varnam that often opens a concert and the kriti, its backbone, with correct ornament, then alapana, the slow, pulse-free introduction to a raga, shaping each phrase across the registers.

  5. Concert performance and raga depth

    Develop full Carnatic concert practice (alapana, niraval, kalpana swaras and pallavi) with mridangam and violin, the usual melodic accompanist. Study each raga's gamaka conventions, vadi and samvadi and defining phrases, joining embouchure control to mature raga knowledge.

About the clarinet

What makes a clarinet

The Carnatic clarinet

The Carnatic clarinet is the B-flat clarinet as South Indian classical music plays it, and ours suits the student and the concert player. A. K. C. Natarajan leads the tradition; he spent decades building a technique for the gamaka-rich language of Carnatic raga on a Western woodwind. Its cylindrical bore gives a hollow, focused low register and a bright, penetrating upper one, unlike the saxophone's conical bore, and its keywork covers the chromatic scale across three registers.

How it plays raga

The bore makes the clarinet overblow at the twelfth, an octave and a fifth, where the saxophone overblows at the octave, so Carnatic players must move fluently through the chalumeau, clarion and altissimo registers. Gamaka comes from embouchure bending, jaw and lip pressure on the reed, with vocal-tract shaping and partial tone-hole cover: kampita, jaru and nokku over the keywork's fixed pitches, with breath shaping each ornament. Its breath-sustained tone suits alapana. It holds a recognised place on the South Indian concert circuit, with a smaller community than the saxophone's or the nadaswaram's.

Choosing one

Two key systems matter: the Boehm system, 17 keys and 6 rings, and the Albert or simple system, which keeps more holes under the fingers for sliding pitch, so ask a Carnatic teacher which they play. Choose a medium-soft to medium reed for bending, and check the barrel and pitch standard.

Histórico

By the usual account, Johann Christoph Denner of Nuremberg added a register key to the chalumeau around 1700 to create the clarinet. A palace letter of 26 December 1802 records four clarinets at the Thanjavur court of Serfoji II. British military bands spread it in the 19th century, beside bugles, flutes and brass, and it served North Indian folk and light music before any classical use. In the South classically trained musicians played it in temple processions and Tamil film orchestras.

A. K. C. (Azhiyur Kuppusami Chidambara) Natarajan studied Carnatic music formally and built the embouchure technique for its ornaments. He had the Tyagaraja Aradhana lift its ban on the instrument, played the Madras Music Academy from the 1960s and the Chennai Music Season and major festivals for over four decades, and recorded widely; later players learned from those recordings. He has received the Sangeet Natak Akademi Award and, in 2022, the Padma Shri.

His students carry the tradition on, occasional players keep it visible on the circuit, and some Tamil Nadu institutions teach it; students still learn from his recordings. Some players have adapted the clarinet to Hindustani raga and meend, where no player has yet matched his standing.

How a clarinet is made

A Carnatic clarinet is a standard B-flat clarinet in five sections: mouthpiece, barrel, upper joint, lower joint and bell. The bore is cylindrical for most of its length, departing from a cylinder at the mouthpiece and flaring through the lower joint and bell, which shapes its register behaviour and colour. Professional bodies are African blackwood (Dalbergia melanoxylon, grenadilla), dense, fine-grained and resistant to moisture and humidity swings; Buffet Crampon makes its E13 of it and its student Prodige of ABS plastic; other student bodies use hard rubber. The exterior is smooth, oiled or lacquered.

The Boehm system keywork has 17 keys and 6 rings of silver- or nickel-plated German silver on pivot rods; the Albert, or simple, system keeps more holes under the fingers. The mouthpiece is hard rubber or crystal glass, with a ligature clamping a cane reed (Arundo donax) to its table; reed hardness, tip and cut set pitch flexibility and tone.

No structural change is needed: the adaptation is in the jaw and lip technique. Barrel length sets overall tuning, and some current models are built at A = 442 Hz, so some players carry two barrels for ensemble tuning.
