Here is a fun exercise that will put your arms in a pretzel. I won’t claim that this exercise is the most essential (or even the most logical) exercise ever, but it covers a lot of paradiddle patterns around the tenors—and it’s just plain fun to play. Some of the patterns are easier, and some of them are harder. There is a continual contrast between standard patterns and not-so-standard patterns that makes the overall flow tricky to navigate. Have fun with “Paradiddle Pretzel”!
