How do you play Guitar Hero drums?

Answer 1

If it appears like a held note such as on the guitar chords, you keep hitting the relative cymbal to the held note, You must successfully hit the note numerous times in quick succession because there is a time limit as to how long between each hit and you can drop the note if you hit it once say every 2 seconds.

Answer 2

You play them like a normal drum kit. The different drums have colours just like the guitar and you hit the drum when it comes up.
