The melody strings are commonly tuned to the same note, or in octaves, while the drone strings are tuned to the 1st and 5th of the melody strings. Tuned in this manner, the instrument is uni-tonic, or not used to
modulate to different keys because the fine melismatic music of India is more concerned with expressing subtle, microtonal pitch increments in a music-theoretic system radically different from Western, predominantly harmonic music; so that modulation to different keys is not considered so important. The melody strings may be tuned to different pitches if desired, however, rendering it multi-tonic, but more difficult to play. The bulbul tarang is most commonly played as accompaniment to singing. Similar to the
Autoharp, a chord can be selected when a key is depressed, and the strings are often bowed or strummed with a pick. ==Related instruments==
