Practice pg. 6 on bells, and exercise 18 on ph. 6-B on snare. For the bell pieces, remember that you can remember the lines on the staff by thinking of the phrase, "Every Good Boy Deserves Fudge," and you can remember the spaces in between the lines because it spells the word "FACE." It is difficult to recognize notes at first, but keep at it, it just takes practice!
For the snare piece, remember to pay attention to the stickings!
