To be honest, the drumming scene here in Singapore isn't very
supported. Anyhow, you may take lessons at Yamaha. I never
personally took lessons from there but from what I heard, their
lessons aren't very effective.
You may buy books and video's to slowly pick up skills. The key in
drumming, I guess, is independence. That is for your 4 limps to be
doing different things at once.
Hahas, trust me, it's normal that your limps fiddle around when you
have drumming injected in your life.
Impossible is impossible!
