Major Scale Formula

Major scales are formed by combining whole step and half step intervals. They are based on the formula W-W-H-W-W-W-H. “W” stands for whole step, and “H” stands for half step. To count up a whole step (whole tone), count up by two physical piano keys, either white or black. To count up a half step (semitone), count up from the last note up by one physical piano key, either white or black.

Using this formula, let’s form the Ab major scale. Our starting note is Ab. From Ab, move up a whole step to Bb. From Bb, go up one whole step to C. Next, we move up a half step from C to Db. Next, we go up one whole step from Db to Eb. From Eb, we move up a whole step to F. Next, we move up one whole step from F to G. Finally, we move up a half step from G to Ab.
