MUSICAL INSTRUMENTS OF INDIA

Natya Shastra, compiled by Bharat Muni, divides musical instruments into four main categories on the basis of how sound is produced.

  1. Tata Vadya / Chordophones- Stringed instruments

  2. Sushira Vadya / Aerophones- Wind instruments

  3. Avanaddha Vadya / Membranophones- Percussion instruments

  4. Ghana Vadya / Idiophones- Solid instruments

(1) TATA VADYA - STRINGED INSTRUMENTS


  • sound is produced by the vibration of a string or chord.

  • vibrations are caused by plucking or by bowing on the string which has been pulled taut.

  • Length of string/wire, degree to which it has been tightened, determines the pitch of the note and also to some extent the duration of the sound.

  • Two Main Types- Plucked & Bowed

  • Subdivided into the fretted and non-fretted variety.

  • oldest evidence - harps in the shape of the hunter’s bow.

  • Veena was the generic term for stringed instruments’ referred to in texts

  • Another class is of the dulcimer type, where a number of strings are stretched on a box of wood, e.g sata-tantri veena-the hundred stringed veena.

  • Santoor, a similar to sata tantric veena instrument

  • A later development are the fingerboard variety,

  • great advantage - the richness of tone production and continuity of sound.

  • increase or decrease in the length of the vibrator wire is responsible for the changes in pitches of notes-swaras.

  • Bowed instruments - the upright(Sarangi) and the inverted(Violin).

Different parts of a stringed instrument

  • Resonator(Toomba) - either made of wood or from a specially grown gourd.

  • Tabli - the plate of wood over this Toomba

  • Danda - resonator is attached to the fingerboard-the Danda, at the top end of which are inserted the pegs-the Khoontis, for tuning the instrument.

  • Bridge- On the Tabli there is a bridge made of ivory or bone.

  • Tarab - main strings pass over the bridge.

  • When these strings vibrate, they add resonance to the sound.

(2) SUSHIRA VADYA- WIND INSTRUMENTS

  • sound is produced by blowing air into an hollow column.

  • pitch of the note is determined by controlling the air passage and the melody is played by using the fingers to open and close the in the instrument.

  • The simplest of these instruments is the flute. Generally flutes are made of bamboo or wood and the Indian musician prefers these due to the tonal and musical attributes of these materials.

  • Excavations of the Indus civilizations have shown bird whistles of clay, and seals which show wind and percussion instruments.

  • There is reference in the Vedas to an instrument-the Venu which was used as an accompaniment to chanting and recitation. There is also mention of a kind of a flute called the Nadi.

Wind instruments are roughly divided into two categories on the basis of how sound is produced. They are:

Flutes

  • double flutes are mostly played by musicians of the tribal and rural areas

  • They resemble beak flutes which have a narrow aperture at one end.

  • One finds references to these types of instruments in the sculptures of the first century in the Sanchi Stupa which shows a musician playing on a double flute.


Reed instruments

  • Reed instruments like the Shehnai, Nadaswaram, etc., have one or two reeds inserted in the hollow beak or tube of the instrument,

  • these vibrate when air is blown into them.

  • reeds are bound together with a gap between them before inserting into the body of the instrument.

  • The body of the tube is conical in shape narrow at the blowing end and opening out gradually with a metallic bell at the farther end to enhance the volume of the sound.

  • A set of spare reeds, an ivory or silver needle for adjusting and cleaning the reeds are also hung from the mouth piece of the instrument.

(3) AVANADDHA VADYA - PERCUSSION INSTRUMENTS


  • sound is produced by striking the animal skin which has been stretched across an earthern or metal pot or a wooden barrel or frame.

  • The earliest references to such instruments have been found in the Vedas where there is mention of Bhumi Dundhubhi; this was a hollow pit dug in the ground and covered with the hide of a buffalo or ox which was stretched across the pit.

  • The tail of the animal was used for striking the animal hide and thus sound was produced.

The main categories are-Oordhwaka, Ankya, Alingya and the waisted or the Damaru family of drums.

Tabla

  • Tabla pair is a set of two vertical Oordhwaka drums.

  • right side is called the Tabla and the left, the Bayan or Dagga.

  • Tabla has a wooden body with a covering of animal skin, this is held together with leather straps.

  • Between the straps and the wooden body, oblong wooden blocks are placed for tuning the drums.

  • syahi(ink) paste applied in the centre of the animal skin, the tabla can be tuned accurately by striking the rims with a hammer.

  • body of the bayan is made of clay or metal and is covered with animal skin which also has syahi paste applied on it. Some musicians do not tune this drum to an accurate pitch.

  • tabla pair is used as accompaniment to vocal and instrumental Hindustani music and with many dance forms of northern India.

  • complicated talas of the Hindustani music are played with great virtuosity on the tabla.

  • Prominent musicians playing the tabla today are-Ustad Alla Rakha Khan and his son Zakir Hussain, Shafat Ahmed and Samata Prasad
