This is pretty straightforward, almost something you can do without writing it out— I've simply transcribed the basic flam exercises from p. 16 of Stick Control into 5/8. I get bored practicing things in a straight march rhythm, and this gives them a little more interest.
I don't follow the instruction in the book about doing each exercise 20 times— if I was going to count repetitions I would do them for 4, 8, 12, 16, or 32 measures. But I just play them for 30 seconds to one minute.
Practice your flams. For some reason drumming-on-the-internet likes to ignore them, but they're important. Please do them. See my page of hand motions for Stone flam studies, or email me for a Skype lesson if you need help.
