Hi Charlie, ok so in BIAB terms, the chorus is the song ... is that right? So if your song happens to be 240 bars long, your chorus should be 1 to 240 times 1, i.e. no repeat.

So the notion of chorus is really only relevant to the notion of creating repetitive backing track chord sequences - is that correct?

In a real song, the chorus can be repeated several times throughout the song but maybe that is more of a printed presentation issue when printing the structure of the song ... is that the terminology difference that I am struggling with?

All the best.
P.
