The first is that the student fails to grasp certain important distinctions. Second and perhaps most important is that the student becomes cut off from the large amount of material which has been published in India. A small amount of time invested in teaching good notation pays its dividends many times over. The use of audiovisual equipment is another area which is very important to a modern approach to teaching. I have been using computers to some degree or another for the last four years with very encouraging results.
Computers appear to have the greatest application in two areas.
The first is automatic lahara generation and the second is the processing and retrieval of compositions from a database. Lahara generation is a process which is very well suited to the computer. A lahara is a small repetitive melody that is used to accompany a tabla. This is most used in tabla solos, but is very important when a student is working on any fixed composition. If there is any deviation from the correct rhythm, then the lahara with its mechanically perfect beat shows the imperfection with an almost embarrassing clarity.
