Keys and the circle of fifths
About 5 minutes
A key is a home note and the scale built on it. Go up a fifth from C and you reach G, with one sharp. Up another fifth is D, with two. That chain is the circle of fifths.
Going the other way, down a fifth each time, adds flats: F has one, B flat has two. Guitar loves the sharp keys, G, D, A and E, because of the open strings.
C, G, D, A, E: each a fifth above the last.

To pass: four out of five right.
