It probably comes as no surprise to anyone familiar with this website that I am a big fan of music apps for the iPhone (and iPod Touch) and so i couldn’t wait to check out an app which claims to make writing music on a piano easier.
ProChords is published by Groundcontrol ApS and does exactly that, select a starting chord and ProChords will give you a selection of chords that work, some obvious, some not-so obvious. With a library of over 8000 chord progressions stored in the app and more being added to the database all the time this is a great tool to spark inspiration and help you steer clear of getting in a rut when it comes to your chord choices.
