p is given much less room in ඛ්‍යාල් than in dhrupad.As the songs are short, and performances long (half an hour or more), the lyrics lose some of their importance. Improvisation is added to the songs in a number of ways: for example improvising new melodies to the words, using the syllables of the songs to improvise material (bol-baant, bol-taans), singing the names of the scale degrees — sa, re, ga, ma, pa, dha and ni (sargam) — or simply interspersing phrases sung on vowels, usually the vowel A, ආකාර් තාන්. තාන්s are one of the major distinguishing features of the ඛ්‍යාල් [2]. Now and then, the singer returns to the song, especially its first line, as a point of reference. Besides the vilambit (slow) and drut (fast) tempos, a performance may include ati-vilambit (ultra-slow), madhya (medium speed) and ati-drut (super-fast) tempos. Song forms such as taranas, thumris or tappas are sometimes used to round off a ඛ්‍යාල් performance.ඉතිහාසය[සංස්කරණය]Khayal was popularized by Niyamat
