C and F
One more look at what you missed.
C sits just left of every group of two black keys.
Wherever you see two black keys together, the white key on their left is C.
F sits just left of every group of three.
Wherever you see three black keys together, the white key on their left is F.
Play every C and every F on these two octaves.
Two black keys: C on the left. Three black keys: F on the left.
Which white key is just left of three black keys?
C, D, E wrap the two; F, G, A, B the three.
So every white key belongs to one group, counting up from its C or its F.
Which white key is just right of two black keys?
Count from whichever landmark is closer.
For G, start at F and count one up. For B, start at C and count one down.
Find the nearest C or F first, then count up or down to the letter.
You have two landmarks on the keyboard.
What you learned
- C sits just left of every group of two black keys.
- F sits just left of every group of three.
- Any other white key is a short count from C or F.
