Scales › G major pentatonic
Notes: G – A – B – D – E
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: E minor.
