Ray Guyll (pronounced gwill as in quill pen) told me this my first year as part of the Woodinville Jazz Ensemble:
1. Quarter notes should be played short.2. Eighth notes on the down side of a beat should be 2/3rd of a count.3. Eighth notes on the up of a beat should be 1/3rd of a count.4. Quarter notes, eighth notes and anything shorter which are followed by a rest and/or end a phrase should be played short and accented.5. Attacks should be with a soft and smooth doo instead of too.6. The following markings and rhythms should be played as indicated:> full value accent^ short and accented – dot. short and unaccented – dit
If you listen or play along with music from the greats like Sonny Rollin or Gerry Mulligan you will be able to pick this out rather quickly. During practice play the piece slowly to help you place the articulation and get the notes under your fingers. Then bring it up to speed.
