By FAR the best chord progressions and MOOD modes!

Where has this gem been hiding? There most be literally thousands of chord app in Apples iTunes Store!
I have downloaded probably 15-20 of those apps, and deleted all but a few up to this point, but I can trash the others because this app is “dope” so to speak! It’s really packed full of cool features.
However there is 1 downside and that is the fact that this Dev doesn’t offer it as an iPad app! (Only iPhone) Maybe if enough people hound the developer they will ad an iPad app. But even with that said the MOOD features makes up for no iPad version!
If you go into the mood mode (once you punch in what key you like) it will give you many different variations of the progression! Just killer! Love this app!

RE: Excellent music prototyping app

I found this app an excellent tool for stimulating creation of songs without having access to or knowing how to play a piano. One can focus on the song itself without being distracted by playing/learning an instrument. It's also useful for relaying your song parts to other players (with or without) instruments. Now if only it would write the words for

This app makes keys, chords and modes simple. If you want a brilliant tool to make music theory work for you in real time, this is your app! Chords, scales, every type of mode in a very simple tool..
