I doubt this thread will live very long.

Just thought I'd share my discovery when analyzing Radiohead - Polyethylene part 2. I thought it was quite interesting how much the song makes use of modal interchange.

Using my trusty chord progression chart you can see that it jumps all over the place:

Verse starts of in A minor:
Am, Em, F, C (C also exists in A Phrygian, so the jump to that mode works very well)

A Phrygian:
(C), A#, Am (Am also exists in A Dorian)

A Dorian:
(Am), Dsus, D, Dsus, D

After having repeated that progression one more time it goes to Lydian for a just one chord. Then it jumps over to Mixolydian. No idea why it works, but it sounds great.

A Lydian:
B

A Mixolydian:
G, D/F#, Em

A Minor:
(Em), F, C

And then it jumps to some major scale for an A and Asus. No idea why that jump works either. There is no C in any of the major modes.

Oh yeah, and the intro/bridge progression goes F, C, G, Asus, A, Asus, A. But I'll let you figure out the modes for yourselves.

Anyway. Pretty cool stuff, but I'm a novice so I'm easily impressed.
Go ahead and share your own discoveries whatever they may be.
