have you play a drum before?
Yes, believe it or not I was it in a band in high school and played the drums. I was quite found of using the hi-hat and the bass drum myself.
waoh thats so interesting, how dont know how to play a drum
It's not too difficult, I learned how to in a muscal school, as standard modern kits are taught there.
is there something like electronic drum?
Oh yes, it's like a special kind of synthesizer or keyboard that lets you play all the standard drum sounds as an alternative!
