I think "western" notation is perfect for notating most rhythms, and certainly fine for this one.And 4/4 in straight 8 notes is perfect for this particular rhythm as played by Bo Diddley, as long as you recognise that the firstnote of a pair is played a little longer than the second at slower tempos.And 12/8 is fine if you want to be more precise. Same with writing out hornpipes: you could use 12/8, you could use 4/4 and dot the first noteof the pair,or you could just do what I do which is to use 4/4 with all notes written as quavers, and remember the rhythm you're aiming at. Musical notation is perfect as far as it goes, but it can only capture a small part of the music....style and sound, swing and heart, they arent so susceptible to dots on paper!
