A few practice items coming up. Here’s the traditional rudimental item Three Camps converted into 3/4 time, two different ways— accenting the quarter notes, or accenting the swing dotted half notes. That latter is harder than I expected.
Something about doing it in 3 encourages you do it faster— I like Three Camps for working on fast singles. And the piece is 50% longer, so it will help your endurance.
Learn each phrase by itself, then put the phrases together according to the form description to make the complete piece. Play as accented triplets as written, and as rolls, doubling all the unaccented notes.
