Scales › A major pentatonic
Notes: A – B – C♯ – E – F♯
Five notes, no half steps: the major scale without its 4th and 7th degrees. It can’t sound wrong, hence its success for improvising, from folk music to pop.
Steps between the notes (W = whole step, H = half step): W – W – W+H – W – W+H.
Relative key: F♯ minor.
