Hi Tano Music,

Thank you for your kind words!

Yes, I purchased the vocals for this song. Then I sat down with my keyboard and tried to play the melody and find appropriate chords. In this process I will often have way too many chords, so the next step is to simplify and find the basic chords that will sound good as a backing track for the song.

Then I start using BiaB with the simplified chords and the audio, but that will often be a little boring to listen to, so next step is to make some interesting transitions between the chords, which will make the music more lively.

In this song I sometimes changes a progression like
Bm /G /D /A
to
Bm BmMaj7/Bm7 Bm6/D7 /A

but of course you always have to use you ears and only do it if it sounds good together with the vocals.

I hope that helps you a little.

Take care,
Will
