Question

what changes were noticed when the indian system of vocal music interfaced with the arab,iraniam and central asian traditions?

Answer 1

Indian system of vocal and instrumental musical interfaced with Arab, Iranian and Central Asian traditions of music. New ragas came to be composed. The Bhakti and Sufi traditions also gave an impetus to new devotional styles of music.

Answer 2

Answer:

The Indian structure of vocal music is old & precedes any Arab, Iranian & central Asian civilisations. It was court music (with the related dance forms worshipped even in tradition) based on the seven notes [Sa Re Ga Ma Pa Dha Ni evenly matching to Do Re Me La So Fa Tee] in which it is embedded even now. I trust Turkish music has 12 notes in place of 7 of ours in an octave, 

Islamic traditional practices without amending it, adjusted Indian music important to a kind of Fusion.
