Pianoपियानो

The piano is a keyboard chordophone in which felt hammers strike steel strings. Bartolomeo Cristofori invented it in Florence around 1700, and it reached India in the late 18th century.

What to look for

When buying a piano for Indian classical music, start with tuning: the piano locks each note to equal temperament, while a raga can shade notes away from it. A digital piano needs no tuning. An acoustic piano can be retuned note by note. In 2020, the raga pianist Utsav Lal told the Indo-Asian News Service that he retunes a few notes to find Yaman's gandhar, its third degree.

On either kind, look for an action that feels even across the keyboard. Pianists suggest a meend, the glide between notes, with quick figures through the target note. KalaSudha sells digital and acoustic uprights and mid-range grands. Ask us for a quote, or for a piano made to order.

Read the piano care guide
  • Tuning: Tune every six months at home, quarterly in studios or changeable climates, holding pitch between A439 and A441. A long-neglected piano needs several pitch-raise passes over weeks: forcing it in one session can crack the soundboard or strip tuning pins. Book the tuning with us.
  • Humidity: Keep 40–50% relative humidity at a steady temperature near 20 °C, away from vents, fires and sun. Dry air cracks the soundboard and loosens the pins, so the piano goes flat; damp swells the board and pitch rises. A Dampp-Chaser system in the cabinet steadies the soundboard, but control the room too. In India's monsoon, humidity can pass 70%.
  • Keys: Wipe key tops with a barely damp cloth and dry them at once, as moisture warps them; no chemical cleaners on ivory or synthetic tops.
  • Action: Dust in the felts slows the keys. Have us remove and vacuum the action; never blow or brush dust out with the action in place. Keep drinks off the keyboard: a spill into the keybed damages parts that are costly to replace.

Learn the piano with us

All courses

You can learn Indian classical music on the piano with KalaSudha online and in workshops, and beginners start at Foundation level. That stage covers hand position and the layout of the 88 keys. Children learn with us as well as adults, so ask us about a starting age and about an instrument size for a younger learner.

Pianists coming back after a long break can start again where they left off, because our courses run in levels. Your teacher reviews where you stand first.

Your route, stage by stage

  1. Hand position & keyboard geography

    Beginners start here, at the Foundation level of KalaSudha's courses. Learn correct seated posture, hand arch and finger weight. Map the 88-key layout and its octaves, and build independent finger movement through five-finger exercises.

  2. Scales & sargam mapping

    Practise major and minor scales in all keys. Map the sargam, Sa Re Ga Ma Pa Dha Ni Sa, onto the keys from a chosen Sa and mark the komal (flattened) and tivra (raised) notes. Learn where equal temperament departs from the shruti of Indian tuning.

  3. Indian raga exploration on piano

    Start with ragas whose notes sit well on the piano's twelve-pitch grid, such as Yaman, Bhupali and Desh. Practise aroha and avaroha, the ascent and descent, and learn how sustain, voicing and quick figures through the target pitch can suggest meend, the glide the keyboard cannot play. Listen to how Utsav Lal shapes a raga on a fixed-pitch keyboard.

  4. Composition & accompaniment

    Learn to accompany vocalists and instrumentalists with chord voicings that support the raga's melody and leave room for its glides. Study A. R. Rahman and R. D. Burman arrangements as models for film-style piano, and Anil Srinivasan's duos with Carnatic vocalist Sikkil Gurucharan to hear a pianist support a singer.

  5. Advanced improvisation & fusion

    Improvise within a raga's ascent and descent over a tabla theka. Explore fusion, pairing the piano with tabla, sitar or violin, and write short pieces that keep the raga's characteristic phrases, building a voice that joins Western harmony to Indian melodic grammar.

About the piano

What makes a piano

What is a piano?

The piano is a keyboard chordophone in which felt hammers strike steel strings, and suits your Western repertoire, film music or raga fusion. Its full name, pianoforte, means soft and loud, because touch sets each note's volume. A modern concert grand has 88 keys over more than seven octaves, about 230 strings and a cast-iron plate holding up to 20 tonnes of tension. No other Western instrument gives one player so wide a range or so many shades of loud and soft. The Italian harpsichord maker Bartolomeo Cristofori invented it around 1700, replacing the harpsichord's plucking with hammers that grade the volume.

A spruce soundboard carries the tone, and copper-wound bass strings and plain steel treble strings in choirs of three give the piano its bloom. A grand's gravity-return action repeats notes fast; an upright returns its hammers by spring in a smaller cabinet; a digital piano needs no tuning. A regulated action feels even across the keyboard.

You can play ragas on the piano within limits. It locks each note to equal temperament, while raga lives on shruti (microtones) and meend (glides): Bhairavi's komal gandhar sits a shade below E-flat, Yaman's tivra madhyam a shade above F-sharp. Pianists run quick figures through the target note to suggest the glide; others choose ragas that suit the grid or let sustain carry the line. Anil Srinivasan, trained in Western and Carnatic music, has played with Bombay Jayashri.

ہسٹری

Cristofori built the first piano at the Medici court in Florence around 1700. Its hammer struck and escaped, leaving the string free to ring while the key stayed down; that escapement drives every piano action since. Viennese makers built the light action Haydn and Mozart preferred, and English makers the heavier action Beethoven favoured. By the 19th century Steinway and Bösendorfer had built the modern cross-strung, iron-framed concert grand.

In the 1800s uprights reached homes, missions and clubs in Calcutta, Bombay and Madras; mission schools trained the first Indian pianists. Indians first heard it in church and at European recitals, and until the early 20th century it stayed in European and Europhile circles, its fixed tuning of little use to classical musicians.

Bombay studio orchestras took up the piano in the 1940s and 1950s. By the 1960s and 1970s S. D. Burman and R. D. Burman made it a core voice in film scores, and from the 1990s A. R. Rahman made it a centrepiece in Roja, Lagaan and Slumdog Millionaire, scores released worldwide. Amjad Ali Khan has worked with pianists, setting slow Hindustani alap beside Western slow movements, and Anil Srinivasan has brought the piano to Carnatic raga.

How a piano is made

The soundboard is the acoustic core: a thin panel of tight, even-grained Sitka, European or white spruce, chosen for its stiffness-to-weight ratio; low-cost pianos may use laminated boards. Ribs glued across the grain stiffen it, and a slight crown under string tension keeps it responsive; a flat board sounds thin. The bridge on top carries string energy into the wood.

Strings of high-carbon steel run from hitch pins to tuning pins set in the pin block, hardwood plies of maple or beech glued with alternating grain. Bass strings wrap a steel core in copper, adding mass without impractical length, and take large, dense hammers. The treble has three plain strings per note, which couple through the bridge for a fast attack and a slower aftersound. A cast-iron plate absorbs up to 20 tonnes of tension.

Each hammer carries layers of pressed wool felt, firm at the core and softer at the surface: harder felt sounds brighter, softer felt sings. Technicians voice it by needling or hardening the felt, and regulate the action, thousands of levers, springs and cloth-covered wooden parts, so every hammer travels, releases and rebounds alike.
