The A Major Scale

The notes of A major are A, B, C#, D, E, F#, G# — formula 1 2 3 4 5 6 7. Key signature: three sharps (F#, C#, G#). Its relative minor is F# minor, which uses the same notes from a different home. Below: the full neck, the chords in the key, and the pentatonic that lives inside it.
