What is the formula for building your scales?

The Major scale formula = 1 2 3 4 5 6 7 C major scale = C D E F G A B The Minor Pentatonic scale formula = 1 b3 4 5 b7 C Minor Pentatonic = C Eb F G Bb So you play the first note of the major scale, then the third note lowered by a half step, the fourth note, the fifth note and the seventh note lowered by a half step.

The formula for creating a major scale is "whole, whole, half, whole, whole, whole, half." half: b to c - Note that you're back where you started at c. If you didn't get back there, something would have been wrong, because as you can see from the keyboard diagram, the same notes repeat over and over.
