Harmonetta Map

Harmonetta Map puts the instrument’s distinctive keyboard at your fingertips. Explore where notes and chords live, compare playable shapes, and practice with a clear visual guide. • Choose a root, chord quality, and optional slash bass note to see matching shapes on the keyboard. • Move a chord by tapping a junction, or browse shapes ranked by touches and hand span. • Tap keys and chord junctions to hear them. • Practice scales up and down with adjustable tempo and note, click, or combined sound. • Build a song as a sequence of chords, choose a shape for each one, and save it to your library. • Set note names and keyboard labels independently for English, French, German, or Latin notation. Designed for Harmonetta players who want to understand the layout, find practical chord shapes, and keep a song’s progression close at hand. The optional tip jar supports continued development; all playing and practice features remain available without a tip.
