Guitar Chord Progression Improviser
Enter your chord progression and see which notes work over every chord - and how to connect the changes melodically with target notes and voice leading.

Alternates audible and silent bars so you have to hold the tempo yourself.
Randomly mutes clicks so you notice when your timing drifts.

What this tool does
Improvising over changes is mostly about two things: knowing the chord tones of the chord you are on, and knowing where the next chord pulls you. This tool computes both for any progression you enter - chord tones, arpeggios, matching scales, target notes and the exact half-step and whole-step connections between one chord and the next - and shows them on a real guitar fretboard in standard tuning.
Example: the V–I resolution in C major
Moving from G7 to Cmaj7, the leading tones resolve by half step: F falls to E and B rises to C. G stays as a common tone and D moves a whole step up to E. Hearing and targeting these movements is what makes lines sound connected instead of scale-shaped.

- B → Chalf step up
- F → Ehalf step down
- D → Ewhole step up
Frequently asked questions
- Is the improviser free?
- Yes. Analysis, fretboard, scales, playback and local saving work without an account. An account only adds cross-device features later.
- Which chords does it understand?
- Major, minor, 7, maj7, m7, 6, m6, sus2, sus4, add9, 9, maj9, m9, dim, dim7, m7b5 (half-diminished), augmented and slash chords like C/E - with sharps and flats spelled correctly.
- What are target notes?
- Chord tones of the next chord that you aim your line at, so the chord change is audible in your melody. The strongest targets are a half step away from a tone you are already on.
- What is voice leading?
- The way individual notes move between two chords: common tones stay, leading tones resolve by half step, other voices move as little as possible. The tool computes these connections for every chord change you enter.
- Does it work on my phone?
- Yes - the chord cards and the fretboard scroll horizontally, and all controls are sized for touch.
