G# Lydian II
I – II – IV – I progression in G# major
G# Lydian II — I – II – IV – I
The G# Lydian II progression (G# – A# – C# – G#) 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 (G#Maj7 – A#Maj7 – C#Maj7 – G#Maj7), the Lydian color becomes even more luminous.
