B Lydian II
I – II – IV – I progression in B major
B Lydian II — I – II – IV – I
The B Lydian II progression (B – C# – E – B) uses a major II chord borrowed from the Lydian mode, creating a bright, unexpected harmonic lift before settling on the subdominant. Made famous by Lennon and McCartney, it sounds simultaneously familiar and surprising. With seventh voicings (BMaj7 – C#Maj7 – EMaj7 – BMaj7), the Lydian color becomes even more luminous.
