Suggester is a tool to assist in the creation of songs and chord progressions. This app will help you find chords that work together. It is efficient and fun; use it to build musical phrases that will carry emotion through tension and release.

Simply touch a chord to hear how it sound like. Press the play button to hear the chord progression sequentially and adjust the playback speed.

You can work either forward or backward:
FORWARD - Pick a scale, then build your song from the chords that the app suggests. That's the quickest way to assemble chords that are compatible.
BACKWARD - From the catalog, pick a set of chords that you like. The app will tell you what scales it matches with. After you have selected the scale you want to use, the app can tell you what chords will fit in with the ones you entered before. That is extremely useful in jam sessions!

To spice things up, you can borrow chords from parallel scales.

You can also explore classic chord progressions.

Use Drag and Drop to reorder chords. Hold your finger on an item for a second to start the drag operation. On iPad, you can also drag chords directly from the suggestions to anywhere in your progression.

Swipe a chord from right to left to delete it.

When you're satisfied, save your experimentations for later reference. Export them by email using either a MIDI file or plain text. You can also open the MIDI file in another app.

Every sound generated with the app is also sent to the MIDI output, configurable in the Options. You can route these notes to another app on your device, an external MIDI port, or remotely to another computer by setting up a MIDI Network Session.

You can trigger chords through the MIDI input.

Sync up your tempo with other apps with the help of Ableton Link.

I love this app, normally it would take me some time to write complimentary chords but since finding this it’s a cakewalk, it really helps you find the best sounding chords for your project and saves so much time in the process. Really let’s me focus on creating rather than theory. Recommend highly A++

Edit: please add ability play chords while you listen to the ones you’ve already chosen! Not sure what’s involved in that but it would be great to hear what you already have and AND pick at the same time!
Still a fantastic app!

I find this app useful for writing stuff like backing tracks, and other stuff. I wish you could have other instruments/instrument effects, Like the piano and electric piano, so it’s be something like guitar,distortion guitar, chorus guitar, etc. I also wish that instead of hitting just chords, you could add individual notes to your song. So
If I wanna transition between chords for instance , emadd9 and Cmaj7, in between those chords I could add a few individual notes, probably e-d-g-a-c. Also there’s a few scales not on here like melodic minor and it’s modes, and a few harmonic minor modes too. Last thing is that you probably wanna use more complex poly chords. Let’s say I have an am/d poly chord, (which is really an with a d note as the bass) I could use a chord instead of just the note d, so it could be am/dm7, or something like that. So basically what I’m getting at is that we should get the chance to combine 2 (or more) completely different chords

Really good app, minor issues

I really like the spirit of this app and its simplicity. Having the ability to sketch out chord progressions while standing on the subway is invaluable. A few things I would like to be improved. Having the ability to set how many times a section should repeat would make song building easier. Some scales are just incorrect, for example the C minor blues scale is spelled as C D# E# F# G A# rather than the more universally common C Eb F Gb G Bb. The difference is substantial: the second note in the scale is a minor third, not a sharp second; the last note a flat seven not a sharp sixth, etc. I believe most people think about the notes that way, unless I’ve been living under a rock. Similarly, certain chords are spelled with weird enharmonics, for example when in C major, the A7 (as secondary dominant) is spelled A Db E G, but we all know that the second note is a major third, i.e., a C, not a flat four (!). That’s just plain wrong.

The newly released version addresses these issues. Thanks for your feedback!
