Ryhthm Course
I've created a rhythm course on YouTube. 46 videos. Hours of training and its all for free. Its called 'Mastering rhythm with Konnakol'.
Konnakol is the art of South Indian Vocal percussion and it has been practiced for many many years.
With this course you can learn to be aware of rhythm and improve it at whatever level you are, whatever style of music you play (or listen).
Hope you'll enjoy, let me know what you think.
