Chord Progression Maker

Create any chord progression and play it with one of the 128 instruments available.
With this app you can create your own library of chord progressions, and explore the limitless possibilities of harmony. It's for both musicians and anyone interested to learn about harmony.
A chord progression is a sequence of chords, for example C-G-Am-F and can be of any length. This app supports all the types of chords. You can set the tempo (the speed) and the time signature (for example 4/4 or 6/8).
In the main screen you can see the chord progression you are working on showed in two different representations: as a sequence of buttons (one for each chord) that you can press to change the value and the type of the chord they refer to, and also as a traditional staff notation, so as to see exactly what are the notes that compose the chords. The buttons' width are proportional to the chords' value, so, for example, a 1-bar chord occupies the whole screen width, while shorter chords only a portion of it. This way you can have an immediate and accurate representation of your chord progression. The chords placed on the staff are touch sensitive: touch a chord and you will hear that chord play. Or, press the Play button the hear the whole sequence from scratch.
The progressions are automatically saved. Your can explore any combination of chords easily and with a lot of fun. If you need to import your work to another device, you can do that! Press "Export all", in the old device, then copy and paste the backup file and finally press "Import all" on the new device.
With the wish you can find this app useful, creative and educational.
