Single Paradiddle-diddle

The Single Paradiddle-diddle (#19 of the 40 P.A.S. certified essential or standard rudiments) is a six note sticking consisting of two Single Strokes and two Double Strokes. The first Single Stroke is accented.

The Single Paradiddle-diddle is one of the phonetic rudiments. This means that it's called a Paradiddle-diddle because that's how it sounds. (This is called an onomatopoeia btw.) 'Pa' is the accent, 'diddle' is a double. 'Ra' is probably just chosen because it makes the word sound good.

The Dynamic Sequence is identical to that of the Double Paradiddle. It's the Sticking which makes the difference between the two.

Now we play the Single Paradiddle-diddle in a triplet feel. First in 8th note triplets, then in 16th note triplets.

In the 16th note triplet example notice that one sextuplet equals two sixteenth note triplets. It's not at all customary to use these interchangeably unless necessary. In this case I did to illustrate this point.
