I Totally Forgot To Mention ThisGood grief, I didn't even mention this in the drum post, and it was one of the top things I wanted to talk about.
When the instructor asked me to play different patterns, he had me look at a note chart. Since drums don't have pitch, each line on the staff is reserved for a type of drum. That means that a horizontal drum note chart looks very similar to a vertical Rock Band note chart, just turned ninety degrees. The one difference is that the hi-hat (usually yellow) and snare (red) positions are reversed from what you'd see in Rock Band.
It's not really that simple, because full note charts can include all different kinds of instructions for playing a section, but at the beginner level, it will look familiar.
