Thursday 9/9 - Enharmonic - A note that has two different names. For example - the black key on the piano between F and G is called either F sharp, because it is a half step higher than F, or G flat, because it is a half step lower than G.
Friday 9/10 - Subdivide - to feel the pulse within the larger beat. For example- in 4/4 time, the quarter note gets the beat. Subdividing would be to count the 8th notes - 1 and 2 and 3 and 4 and.
