It can be even simpler with intervals: 1 is a half-tone, 2 is a whole tone Major scale: 2 2 1 2 2 2 1 Minor scale: 2 1 2 2 1 2 2 etc They sum up to 12 (octave

It can be even simpler with intervals: 1 is a half-tone, 2 is a whole tone Major scale: 2 2 1 2 2 2 1 Minor scale: 2 1 2 2 1 2 2 etc They sum up to 12 (octave) Now that you got the theory, practice playing them evenly from every note and make sure they sound right. Fingerings are a separate story though.
