Indian Classical Vocal Music is principally vocal centric with musical form intended to enhance vocal performance. The major forms of vocal recitals are Khyal, Gazal&Thumari. The music took shape during Vedic times with singing of sacred texts.
Indian classical music has seven basic notes with five interspersed half-notes, resulting in a 12-note scale. The performance is set to a melodic pattern called a raga characterized in part by specific ascent (aroha) and descent (avaroha) sequences, which may not be identical. Other characteristics include "king" (vadi) and "queen" (samavadi) notes and characteristic phrases (pakad).
