| The Circle of Fifths. Note the "B-E-A-D" patterns. Naturals in black, Flats in red, Sharps in blue. Most commonly played keys on outside of wheel, less-commonly played keys on inside. Note that the sharp key is the same as the equivalent flat on a keyboard or a harp. In memorizing the key progressions, one must learn only one sequence of seven letters; they repeat three times from F to B: once plain, once with sharps, and once with flats. Note that F is also E#, as C is also B#, so you actually have a third B-E-A-D. |
