What to look for

Listen to the treble head first. Its permanent black load, the soru or syahi, sets the pitch: a fine one sings and an uneven one sounds muddy, so tap the head across its stroke zones before you buy. The load disc, 4 to 6 cm across, should be centred true. Student mridangams have machine-fitted heads; mid-range instruments have hand-applied syahi and quality jackfruit shells.

The shell should be one block of jackfruit wood, seasoned for at least a year to resist warping. Choose the size for your pitch: the lower-pitched taggu shell is about 61 cm long and the higher-pitched hecchu about 56 cm, and a concert mridangam is tuned to the performer's tonic. Ask us for a quote, or for a mridangam made to order.

  • Tuning the right head: Tap the gatta or straps with a smooth stone: towards the shell raises pitch, the other way lowers it. Uneven tension is the commonest fault, so work round the head until it sounds one pitch all round, checked against a sruti box or tambura; the straps link both heads, so recheck the other. Allow ten to twenty minutes. Match the edge note to the chapu stroke, and ask us before scraping or adding to the load.
  • Kanji: Cook fine semolina with water to a thick paste, cool it and press a disc onto the thoppi: wider or thicker lowers pitch, smaller raises it, and too much stops the gumki. Remove it all after the concert, as dried paste harms the skin.
  • Humidity: Damp slackens the heads and dry air splits them. Store the drum in a padded bag away from vents, sun and temperature swings.
  • Lacing and load: Replace frayed lacing; rough gatta scratch it and speed its wear, so smooth them with fine sandpaper or replace them. Professionals re-lace yearly.

Learn the mridangam with us

All courses

Start the mridangam with KalaSudha, online or in a workshop: beginners begin at Foundation level. Foundation sets your hands on the two heads and teaches the first strokes, each syllable spoken aloud as you play it. We teach children as well as adults, so ask us about a starting age and about a drum size for a younger learner.

If you stopped for a long break, our courses run in levels and you start again where you left off. Your teacher first reviews where you stand.

Your route, stage by stage

  1. Hand position and basic strokes

    In KalaSudha's courses, this is Foundation level, where beginners start. Set your hand positions for the two heads, the treble valanthalai on the right and the bass thoppi on the left. Learn the foundational strokes tha, ki, thom and nam with fingers and palm, speaking each syllable as you play. Work for even tone and a clear separation between open and muted strokes.

  2. Syllable system and solkattu

    Study the full syllable set, solkattu, and vocalise each pattern before you play it. Students learn rhythm through these spoken syllables tied to hand positions, without notation: speaking trains the mind to hear a structure before the hands play it, the centre of Carnatic percussion teaching.

  3. Tala cycles

    Practise keeping tala cycles at a steady tempo across the main Carnatic talas: Adi (8 beats), Rupaka (counted as 3 beats, or as 6 aksharas, the counting units of a tala), Misra Chapu (7 beats) and Khanda Chapu (5 beats). Develop the ability to subdivide and recombine beats without losing the tala.

  4. Accompaniment skills

    Learn to accompany a vocalist or melodic instrumentalist. Follow the phrase structure, keep the tala steady and set your volume so the lead stays in front. Practise with singers and players until you can answer improvised passages phrase by phrase without losing the cycle.

  5. Advanced patterns and improvisation

    Study the tani avartanam, the percussion solo, which the mridangam opens before the others take turns and all converge on a cadential ending. Learn korvai, mordhana (cadential patterns) and cross-rhythmic layakari, speaking each passage in sollu, then build your own korvais and a tani with a clear dramatic arc.

About the mridangam

What makes a mridangam

What is a mridangam?

The mridangam is the double-headed barrel drum of Carnatic classical music, and ours suits the student and the professional accompanist; no Carnatic ensemble plays without one. Across the lap, the right hand plays the treble valanthalai and the left the bass thoppi, so one drum covers the registers the tabla splits between two.

What makes a great mridangam

The shell is one block of seasoned jackfruit wood, which holds its shape through South India's heat and damp. The treble head's permanent black load, the soru or syahi, sets the pitch: a fine one sings, an uneven one sounds muddy, so tap the head across its stroke zones before you buy. Before each concert the player presses fresh semolina paste, kanji, onto the bass head for its deep thom.

How it is played

On the treble, tha is open, with index and middle fingers; ki is muted near the edge; din rings at the edge by the load; nam strikes both heads. The bass gives thom and the sliding gumki. These syllables feed solkattu, korvais and konnakol. The mridangam follows the singer through neraval and kalpanaswaram, answering phrase by phrase, and fills held notes and pauses with light rhythm that keeps the pulse without crowding the melody. Then it opens the tani avartanam, the percussion solo. Palghat Mani Iyer made it the singer's active partner, and Umayalpuram K. Sivaraman shaped his strokes to the melody's phrasing.

Historique

The Natyashastra (c. 200 BCE–200 CE) names the mrdanga among its principal drums, and temple sculpture at Chidambaram, Thanjavur's Brihadeeswara and Belur shows early barrel drums.

Under the 17th- and 18th-century Thanjavur Maratha court it became principal accompanist to the kritis of Tyagaraja (1767–1847), Muthuswami Dikshitar (1775–1835) and Syama Sastri (1762–1827), the core repertoire. Thanjavur and Mysore court musicians developed its syllables and tani avartanam through the 19th century. The Thanjavur style, oldest and most widely played, values clear strokes, tonal separation and fidelity to the composition; Pudukkottai, through Dakshinamurthy Pillai, heavier bass and cross-rhythm.

Palani Subramania Pillai (1908–1962) gave the Palani style its vigorous right hand and its tani avartanam, which have shaped leading players for 60 years. Palghat Mani Iyer (1912–1981), the 20th century's most influential player, set the standard for close accompaniment and recorded with M. S. Subbulakshmi and G. N. Balasubramaniam. Palani-style player Karaikudi R. Mani defined high-energy tani avartanam and founded Sruthi Laya. A systematic approach to its structure made him the late 20th century's most influential teacher, training hundreds of today's players in India and abroad. Their recordings remain core study material; most players trace their line to one style while drawing on others.

How a mridangam is made

The shell is a single block of jackfruit wood (Artocarpus heterophyllus), seasoned for at least a year to resist warping. Makers around Thanjavur and Chennai rough-cut it on a lathe, then hollow and sand smooth a bore that widens at the centre and tapers to each end, judging it by tapping and listening. Many are Dalit Christian craftsmen.

The right head, the valanthalai, is a goatskin ringed with hide that carries the black load: iron-bearing powder bound with cooked rice, laid in many thin layers over a rice-paste base and struck between layers, up to fifty of them. A disc of 4 to 6 cm, centred true, sets the pitch, usually C4 to F4 for concert players. Once the load sets hard, makers tune the head by tightening the lacing until its edge rings at pitch. In 1920 C. V. Raman and Sivakali Kumar showed the load gives the head five near-harmonic tones.

The left head, the thoppi, frames goatskin with heavy buffalo or cow hide and has no permanent patch. Water-buffalo hide or nylon straps run between the hoops over wooden kinnaram, with gatta for tuning, and the player adds fresh kanji to the thoppi before each concert.
