By simply following the pattern of tones and semitones, it is possible to construct a major scale starting on any of the twelve notes of the chromatic scale.
The scale will be named by the note it starts on. This note is also referred to as the key note.
Here are several more major scales. Play them slowly and evenly and name each note out loud as you play it.
D major scale
E major scale
Bb major scale
Ab major scale
Now that you know how major scales are constructed, try writing out and playing major scales built on the notes A, B, F#, Eb , Db and Gb . Some will contain sharps, while others will contain flats.
Remember that the scale is named from its starting note and all you have to do is follow the pattern of tones and semitones.
