Suggester

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.
