I love songwriting helper Apps. ProChords helps you find the next chord. I was using it last night and it definitely helped me make a progression I wouldn’t have thought of on my own. It’s a bit more than your standard App at $8.99 and keep in mind your still doing to have to work hard to create a song.
“ProChords is a hand held road map of chords from 9000 songs. So if you are working on a song Fx. “Am7, Em7, Am7, Em7″ and don’t know how to get out of the loop. Tab it into ProChords and you will instantly know 31 different ways to continue. It makes it fun to explore odd chord progressions and get inspiration for more original songwriting” – prochords.dk
