Rudiment Section #38
40 P.A.S. Standard Rudiments
The Ratamacue (#38 of the 40 P.A.S. certified essential or standard rudiments) is a compound rudiment. It's comprised of a double grace note in front of a Single Stroke Four ending on an accent. So it's in fact a Drag and a Single Stroke 4 combination. This is a hand-to-hand pattern which means it alternates between starting on the Right Hand and the Left Hand.
The Ratamacue is one of the rudiments with a phonetic name. This means that it's called a Ratamacue because that's how it sounds.
Notice the Double Paradiddle sticking in here.
This exercise omits the second note of the Ratamacue in beats 1 and 2. This gets you even more intro a triplet/shuffle mindset.
