Find a chord
Browsing leaves the progression untouched.Borrowed colors and applied dominants
These reach outside the main collection. The label describes their source or possible target.
Keep the root. Compare the color. This catalog is independent of left-hand button recipes.
Pick notes to add them below. The first is the bass. Move, replace, or remove notes to try a different order.
Your notes, in order
Choose a note above to begin.
Tap a staff note to edit it. Pitches stay within one octave above the first note; changing the order does not set a rhythm.
Root motion, not a ranking
Neighbors are a perfect fifth apart. Click a root to prepare a chord, not to change the key.
Start with a musical idea. Preview the phrase, then insert it at the chosen gap.
Synthesized chord sketches, not instrument voicings. No sound until you press Hear.
Choose material
Notes are bass first. A bare C is one note; CM is a major chord.
Select pitch classes, bass first. Choose a selected note again to remove it.
Load a progression or exercise
Loading replaces the current sequence. Save it first if you want to keep it.
Notation scratchpad
A separate notation draft, not automatic harmonization. Link imports are not supported.
