Understanding Bb Mixolydian
Names and spellings
A mode is named by the note it starts on, not by the major scale it comes from: D Dorian uses the notes of C major, but its tonic is D and its chords are built from D. The same mode name on another tonic is a different scale with the same pattern.
How it is built
On Bb the mode is Bb · C · D · Eb · F · G · Ab, following the step pattern W W H W W H W. Against the major scale on the same tonic, only the seventh degree differs: mixolydian flattens it.
Flattening the seventh removes the leading tone, so the scale loses its pull toward the tonic and gains a dominant-seventh chord on the first degree instead.
How it is used
It is the sound of blues-rock, of Celtic and folk melody, and of any riff built on a dominant seventh that never resolves. It is also the default scale over a V7 chord in a functional progression.
The ♭VII chord it produces — a major triad a whole step below the tonic — is the other giveaway, and it is everywhere in rock.
