When you buy a drum kit, it usually has a simple pedal to play the kick like this:
Heavy metal and hard rock bands have a drummer who uses a different pedal to be able to play faster. Today, my new drum teacher brought one of these pedals to the class. It name is "Double pedal", look a picture:
After mounting it, my teacher showed me a book to practise with double pedal from the beginning. I've tried during little time and then he told me that I could do what I want, I could practise any rhythm I want or any song I listen! Great! It has been a wonderful although short experience, but I was happy. Also, the pedal I've tried is a very good and expensive pedal, so better.
In the end of the class, my teacher told me, he's going to bring the pedal to the next class too. I'll wait...!
