Bb Mixolydian Scale on Piano
The Bb Mixolydian scale sounds bright but unresolved. It runs Bb – C – D – Eb – F – G – Ab and is written with three flats.
It shares its key signature with G minor, its relative minor.
Interval Circle
All twelve semitones, root at the top. Filled dots are the notes of the scale, the outer numbers are their degrees, and W / H mark the whole and half steps between them.
About This Scale
A major scale with a flattened 7th. Losing the leading tone removes the pull back to the tonic, so the scale can sit on a dominant chord indefinitely — the sound of blues-rock riffs and Celtic tunes.
Fingering
Right Hand (ascending)
4-1-2-3-1-2-3-4
Left Hand (ascending)
2-1-4-3-2-1-3-2
Why this fingering
3 black keys (Bb, Eb, Ab) sit in this scale, and the thumb has to avoid them. In the right hand the thumb crosses under onto C and F; let the elbow drift slightly outward as it passes rather than twisting the wrist.
The blue dots on the piano below show which keys to press — they turn green when you play the right note.
