I have lots of video resources on my website which show rhythms visually. All types of rhythm from 4/4 and 6/8 to complex polyrhythms and drum rudiments:
These videos all have sound as well, but indicate the time so precisely, like a conductor's baton, that you don't need the sound to follow the rhythm.
They should be ideal for deaf musicians who want to learn about rhythms or improve their timing and rhythm - Deaf Musician's Metronome
- as well as going silent, the bouncing visuals are also hidden. So you need to see if you can keep going through the silence / hidden section and still be in time when the bouncing visuals return again.
