New Western Instrument Adaptations
Many western instruments started to be used in India during the British Raj, either in military bands or in palace bands. They were also used in film songs. Impressionable young minds took interest in many of these instruments and mastered them and adapted them to the needs of Indian Classical Music. But the success of an instrument in the classical tradition comes only when second and third generation artists gain mastery of the instruments and become successful concert artists.
Most of these instruments are constructed to produce 12 tempered notes in an octave as used in western music. Thus it becomes difficult to use them to produce other tones, quarter tones and other microtones, that are used in Indian Classical Music. Also, the instrument may not have the dynamic range to faithfully play Indian Raagas. Thus either the instrument has to be modified or the playing technique has to be changed to suit the needs of Indian Classical Music.
Guitar
Bringing guitar on the Hindustani concert stage goes to Pt Brijbhushan Kabra. Like many other pioneers, he was also self taught. He learnt classical music, mostly by listening to the great masters on the gramophone and practicing on the Hawaiian guitar, which he liked. He modified the guitar by adding a bridge and chikari string to it. Together with Pt. Shiv Kumar Sharma he played in many Jugalbandhi concerts. Call of the valley, an immensely popular light classical album recorded by them, along with Chaurasia, introduced guitar as a classical instrument to a large number of people.
To Pt Vishwamohan Bhatt goes the credit for introducing guitar as a Hindustani classical instrument to the western audiences. He experimental recordings with many western and eastern artists have been well received. He also won a grammy for one such effort. Pt Bhatt has modified guitar to suit Indian classical needs and calls it Mohan Vina.
The Guitar was introduced into Carnatic music by Sukumar Prasad in the seventies. Sukumar Prasad and his successors adopted the standard electric Guitar for Carnatic music unlike Hindustani musicians who have always used some form of a modified Guitar. One of the current well known exponents is R Prasanna. Though guitar is constructed basically to produce western 12 tempered notes of an octave, the playing technique has been modified to play Gamakas, thus making it possible to play all the Ragas, including complex ones like Todi (Prasanna on Guitar).
