A flam rudiment that you're likely to run into when you're learning the drums is something called the flam accent. Now the flam accent is basically built off of a triplet figure. Now triplets are counted as one triplet, two triplet, three triplet, four triplet, three notes for each grouping.
The flam itself goes on the first note of the triplet accent, and you have two tapes following it, which creates this alternating rudiment. So what you're going to do is you're going to start with what's called a right flam, which is the right stick up and the left stick close to the drum. After you strike the right flam, you're going to follow with a left tap and a right tap, and that's your first grouping.
What you'll notice is it alternates now being a left flam, for now your left stick is up and your right stick is close to the drum. You'll now flam that note, followed by a right tap and a left tap, and then the right stick comes up, so you're basically doing a flam tap tap flam tap tap, which is alternating. Slowly, it's going to look like this.
Some of the rudiments are a little tricky to remember, but this one is a good one with the name, because all you have to say to yourself is flam accent flam accent, and it should dictate exactly what you're supposed to play, a flam on the first note, two tapes following and alternating.
