What’s going on with the strange rhythm of Radiohead’s Pyramid Song?
It feels like it stops and starts, and it’s hard to place the downbeat – Is it really in 4/4?

The key is understanding its unique 2 bar rhythm, outlined by the piano, which consists of 2 dotted quarter notes, followed by a half note which carries across the bar, followed by 2 more dotted quarter notes.
It is also a heavily swung rhythm, which is something that might not be immediately apparent by listening to the unaccompanied piano.
If you break down each bar into 8th notes – it might be a little easier to understand. You can count it 3-3-4-3-3.
So if your mind has been melting while trying to internalise this weird rhythm while trying to learn Pyramid song in Melodics on Drums or Pads – this will help clear things up!
