Mr. Laureano, I was wondering if I could receive some advice for the tonguing on the Royal March movement on this piece. I can't seem to get the quintuplets even or clean for the life of me, I've slowed them down and have tried a variety of different tonguing syllables. Any suggestions on how to play this excerpt, the articulation and/or some steps to achieve the goal would greatly be appreciated, I'm actually having some similar problems on Ravel's Piano Concerto but not as bad, tonguing does not seem to be my strong point in my playing, thanks a bunch!
