When opening Klimper, it will provide you with a palette of chords found in your current project's scale, organized in a easy to navigate way that lets you experiment with various chord combinations without having to dig through submenus:

To explore chords, you can preview chords by simply clicking/selecting them.

Chord Colours

Green: Major Triads and their extensions

Purple: Minor Triad and their extensions

Gray: All other chord types (power/suspended/augmented/diminished chords)

A filled chord circle means the chord is fully within the project's key, while a hollow circle means at least one of the chord's notes is out of key.

Creating Chord Progressions

To create a chord progression, drag the chord to the sequence bar on top of the palette. Initially, this will automatically create a new section containing the chord. You can add more chords to the same section, or you can drag it to the left/right of an existing section to create a new section. Drag the end of a chord or section to edit it's duration.

 

 

To select multiple chords or sections, you can hold down the shift-key.

To duplicate a chord or a section, hold down the alt/option key and drag the selected items to it's target.  

Finding Chords Matching a Melody

1. Select a melody track to open it's piano roll
2. Select the notes you want to explore matching chords for
3. Go to the chord palette and select "Match against selected notes" from the menu 

 

Borrowing Chords

By default, the chord palette follows your project's home key, as indicated by activated house icon:

Adjacent Keys

To borrow chords from adjacent keys, click the left/right arrows. This way you will step along the circle of fifths, so as a rule of thumb, the more steps you take, the more exotic the chords will be to your project's home key.

Parallel Modes

You can also switch easily to parallel modes by clicking the current mode.
