The first set of experiments was conducted to specify the qualified priority measurement as heuristic values; TLevel, BLevel, SLevel, ALAP
, and NOO were considered, and finally the results showed that ALAP
is more appropriate.
In a longer and more elaborate alap, such as one can hear today in the dhrupad style of North Indian classical music, the octave might be unfolded in several stages, introducing successively higher pitches before the upper octave is reached.
22) We can assume that alapti would in practice have been improvised, no doubt at greater length than in the very short examples that Sarngadeva gives: today the alap of a dhrupad performance, in which the unfolding process would be repeated several times at successively faster tempos and in different styles, might take half an hour or even more.
