Improvisation plays an essential role in Persian Music and it is more based on interpretation of the Dastgah feeling and principles which maestros have made. A good improvisation needs good skills on instrumental techniques or singing and complete knowledge of Dastagahs and Avazes, melody and rhythm structure of their Gushe’s and their arrangement order.
There are three methods to have a masterly performance of Persian Music :
1. Even though it seems that it is not necessary to improvise in order to play the Radif, the musician does it in some cases because it is not possible to separate improvisation from Persian music.
2. In playing Phantasy music, they use unusual modulations. Performance begins in an accidental point and goes throughout the Gushes very freely.
3. Morakkab-Khani is a very difficult style when the musician starts in a certain Dastgah and then goes through some other Dastgahs and at the end goes back to the first one.
