B♭ Lydian is the 4th mode of the F major scale. Both share the same 7 notes — Lydian starts on the 4th degree (B♭) instead of the root (F).
The only difference is the 4th degree. B♭ Lydian has an augmented 4th (E), while B♭ major has a perfect 4th (E♭). That raised 4th is what gives Lydian its signature dreamy, floating quality compared to the grounded sound of major.
