Answer to Question 1
Ud Taqasim in Maqam Rast is an excerpt of a ten-minute-long improvisation (taqasim) by Mr. Al Asadi performed on ud, recorded July 2000 in Nazareth, Israel. In Arab music, a solo taqasim can occur as a prelude to a composition, in a space between composed passages of a performance, with an ensemble providing a rhythmic-melodic ostinato in the background as in Al-Shagal, . . . or as a performance in and of itself
As in the Call to Prayer: Azan initial musical statements are separated by pauses and they get longer, higher in range, and more decorous as the improvisation continues.
Musical ideas are grouped together like words into phrases and phrases into sentences. Phrases and sentences are organized into paragraphs. Phrases, sentences and paragraphs all feature concluding remarks' or cadential statements called qaflat (s. qafla) a technique that is absolutely essential to instrumental improvisation in Arab music.
Significant musical features: non-metric taqasim; initial phrases separated by pauses and elaborated upon as the music proceeds; the intonation of the Arab maqam; and the significance of the qafla (cadential statementsee above)
