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 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 from our huge catalog. Your exotic chord type is not in the catalog? You can still build it by creating a custom chord.

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.

Export your songs as audio, MIDI or text.

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 a MIDI Network Session.

You can trigger chords through the MIDI input.

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

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

You can choose between the english notation (C, D, E) and the fixed-do notation (do, re, mi).

It includes all the features you like from the iOS version, plus a bunch of improvements: Multiple documents at the same time, drag and drop between apps, right-click menus... and more! The iOS version is sold separately.

Really Useful and Nicely Laid Out

I picked up Suggester about a year and a half ago. It was great then and has only gotten better since. The developers keep updating this on a pretty regular basis which is something I value.

The drag and drop feature is nice for both chords and rests. There are lots of reasons that I’m happy with it, but the #1 thing I like most is running Suggester with Logic projects as I’m working on them. I can audition chord progressions in any of the virtual instrument tracks I’ve setup in Logic right from the Suggester app.I can also drag and drop chords directly from Suggester into Logic projects. Being a guitar player learning piano, these features have been helpful in keeping me composing while I learn.

One thing I’d love to see in a future update is a larger and more comprehensive library of chord progressions that I could drag and drop to alter notes and timing. I understand chord progressions and have some theory under the belt, but sometimes having a number of chord progressions in a specified key would be super helpful for inspiration when writer's block strikes.

Suggester is an excellent addition to my music production arsenal.

I've been using Suggester for about two months. It has been extremely helpful on an arrangement updating project. I've been telling my music making friends about it. This supplements my musical abilities and makes up for my inability to compose and arrange music on the piano the way I would like to. This app is sooo easy to use and is reasonably priced. I was surprised to have received several updates since purchasing it. Long story - short I love it.

a little klunky but still the best available

The interface here is a bit klunky. I keep trying to do things like duplicate chords or sections and they aren't supported gestures. And there are dozens of others like this that are just very unlike most mac applications. And there's no meter or bar counter so I'm constantly counting manually to see how long my section is so far.

But this is still the fastest and easiest app I've tried for banging out chord changes. Easy to audition new chords. All the chords I look for exist. And the chord organization makes sense. (None of which are true with many others). The sounds are minimal but completely appropriate for this.

My wishlist is long, but I use this app often and I recommend it frequently.
