It has come to our attention that there is a typo in the stickings on page 19 (Timing Patterns), measure 4, beat 2. The second line of stickings (on the repeat) should read "R L R" on the "ee-and-uh" rhythm. This has been corrected for the next printing.
Note that the sticking is correct on this exercise as part of the full sequence on page 19. We apologize for any inconvenience!
