I've been practicing Arban's Trumpet Studies book and have a question.
In Scale Studies (pg 64) exercise #16 contains 16th, 32nd, and 64th notes. See Wikipedia for images of notes.
My question is, Why does Arban's show 10 32nd notes per beat? And 14 64th notes per beat? When other sources says there should be 8 32nd notes per beat, and 16 64th notes per beat.
Is this wrong? Please explain if this is correct and if so how?
