Major (Ionian) · B♭ · Guitar
The B♭ Major scale is B♭ C D E♭ F G A — formula 1 2 3 4 5 6 7, step pattern W–W–H–W–W–W–H. Use it over B♭maj7: it is the scale for the I chord (maj7) and any major-key tonic; the default over Imaj7 in a ii–V–I. Below, every note is marked on the fretboard in standard tuning; press play to hear it on a synthesized guitar while each note lights up, or tap any fret to sound that note.
