Chords that work together.

Ableton Link

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.

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

Simply click 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.

Explore new territories by using modulation.

Browse the classic chord progressions to find inspiration.

Use Drag and Drop to reorder chords.

Every sound generated with the app is also sent to the MIDI output, configurable in the Preferences. You can route these notes to another app, an external MIDI port, or remotely to another computer by setting up a MIDI Network Session. It's also possible to export to a MIDI file or plain text.

Drag a chord directly into any app that supports MIDI drag and drop, such as Logic Pro X.

It includes all the features you like from the iOS version, plus a bunch of improvements: multiple documents at the same time, full support for undo/redo, copy paste, improved drag and drop, right-click menus... and more!
