Suggester 2 is available now for iOS and macOS. Check it out!

Suggester is a tool for writing 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.

Select chords for their harmonic function. The app makes full use of the roman numeral notation.

Simply touch a chord to hear how it sounds. 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!

Pick chords and scales from our huge catalog. To go even further, you can create your own custom scales and custom chords.

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

Explore new territories by using modulation.

Browse the classic chord progressions to find inspiration.

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.

Tap the note button on the left to change the duration of a chord.

Swipe a chord from right to left to delete it.

Export your songs as audio, MIDI or text.

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.

Use drag and drop between apps! ChordPadX and Suggester can communicate through drag and drop. You can also drag pads and chords into another app if it supports MIDI drag and drop.

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

In the free version, some of these features are locked. Reach full productivity by purchasing a Full Unlock. You only need to buy it once for all your iOS devices. To unlock your purchase on another device, select “Restore Purchases” in the Options. The macOS version is sold separately.
