Here's a jam inspired by The Cure's Caterpillar... just lay down a G & A and away you go. Have fun!

Here's a simple looped arpeggio A & D chords very reminiscent of REM I think you'll agree with some free-form noodling around.

A simple 12 bar groove loop reminiscent of the Beatles Taxman I think?

Here's a thing... I don't know what but I played Em, C, and Am and it sounds like this!
