When compared to the inverted flam tap, the flam tap is an easier drum rudiment to master and to get up to speed. You can think of it as a double stroke roll with a flam on the first note. The sticking pattern in the inverted flam tap is an offset double stroke roll instead – the doubles start on the “and”. It’s this offset that gives it the moniker “inverted”, because the double stroke is starting on the tap instead of on the flam.
