Yeah its better if you can find someone who teaches privately coz usually its far cheaper and they teach alot more indept. Ppl from yamaha and all though are qualified and experienced are constrained to the syllabus given by the school itself..therefore you'll be learning at the pace set for you and not on your on. Basically if you're a prodigy or smtg and learn pretty damn quick, their just gonna slow you down.
I have a friend staying in taman desa whose been giving private lessons for drums for over 2 years dy. He used to teach at mahogony last time as well. I think he charges RM 100/ month and one hour for a class also. So yeah 25/hour. Anyway here's his no. 012-3853717 if you guys interested.
