Absolutely, my wife and I write Gospel songs and BIAB allows us to try out phrases in different styles and chords.
I keep telling her that she is too sweet and we need some darker minor chords to catch everybody's attention.
It doesn't take long before a song starts developing.
Since I am instrument challenged, I can't play a lick on anything, this program saves my butt time after time.
I'm just getting into loops and user tracks and I"M sure driving the real musicians here crazy with my strange questions. But...this forum and software has helped where nothing else could even come close.
Just put a few chords in, doesn't matter if they're right or wrong, choose a style and let your hears see the music.
No judgements, just sounds till you start to hear a song develop in your mind. Add or change a few chords or styles, change the tempo. More than likely you'll find something to work on.
Just 2 cents and change. (That's a phrase that's been running around in my head for several years)
