Poetic Drumming is absolutely the best Tabla Book out there. I think I own at least 90% of the tabla books around. Aloke Duttas earlier book, Lessons and Practice is outstanding as well, (generally this one is for less advanced students, however there is essential valuable material in it as well)Of course lessons from a teacher a neccesary to set the hands among other things. With a good Ustad these two books are perhaps the best supplemantal training available. I use material from those two books almost as much as I use material I 've gotten from my Ustad.
