This PDF document sets out 5 regular rhythmic matrix structures and all the rhythm cells. There are clear instructions on how to improvise rhythms (i.e. rhythm only – no harmony or melody yet) using these rhythm cells and matrix structures as you chant the relevant mantras. Familiarising yourself with theses rhythmic elements is a very significant area of study.
Once you are familiar enough with the new matrix structures and all the rhythm cells you are ready to improvise and read using them. This PDF provides instruction for improvisation practice and 7 sight-reading studies.
