A and B parts in BIAB.

Different chord progression for chorus.

Increased volume in chorus.

Add instruments in chorus. Maybe even use the same RealTracks again on additional tracks.

Sing at the lower end of your range in verse, at a lower level then sing at the higher end of your range and belt it out in the chorus.

I read somewhere that the best approach is to build your chorus first with lots of instruments, volume, fx, etc. Then remove stuff for the verses.

Another suggested technique is to have steps/levels of building your song. The steps/levels just refer to overall energy/volume/complexity/etc.

So, your first verse might be level 1 and your first chorus level 6. Then verse 2 is level 3 and chorus is level 8. Then bridge might drop all the way back down to level 2 while the final chorus goes to 10.
