Band in a Box has a number of features to help with song flow (or song layout if you prefer).
DefinitionsEditFor the purpose of this article chorus will be used to mean one play through the repeat signs. Where the more popular use of chorus, that is in terms of lyrics, is required chorus/verse will be used.
One Long ChorusEdit
A song can be entered into the chord sheet as one long chorus with intro, verse/chous, bridge, verse/chorus, outro. While this is the simplest way to enter a song it isn't necessarily the best way. First of all, BiaB only allows 255 bars on the chord sheet so your song must less than this. Second, this method involves a lot more chord entry, although copy and paste can reduce the work. Repeating sections only need to be entered once.
