Scale Formulas
A scale formula shows you how the notes of a scale relate to the Major scale. For example, the Major Pentatonic scale has five notes, which are the same as the 1st, 2nd, 3rd, 5th and 6th notes of the major scale. On the table below you can see that the Lydian scale is the same as the Major scale, but the 4th note is sharp (1 semitone higher), and the Mixolydian scale is the same as the Major scale, but the 7th note is flat, (1 semitone lower).
