Suggestions for the next chord in your progression are based on a machine learning algorithm trained on over 10,000 songs. You can use your phone's microphone to recognize the chord that you are playing, and new suggestions will appear. As you build your progression you can change tempo, instrument, and the number of repeats. You can hear any chord and see its diagram on guitar or piano. When you are all done, you can share a progression or save it for later.

Great app for breaking creative blocks

I really like the way you can quickly try out ideas. I work on a search engine and have often thought predicting next chords is similar to the approach we have of completing search terms using machine learning.
A couple of things that would be great to add would be midi file export and song “sections” eg verse chorus bridge etc to keep related song sequence ideas together but separated.
Great job!

Fantastic app!

This app is absolutely brilliant! A perfect tool for any song writer who wants to step away from pure theory writing and have some inspiration to break out of a creative rut!
