Ukulele Chord Diagrams

A ukulele has only four strings and a neck most players use within the first five or six frets, which changes what a chord finder can do: instead of guessing at one good shape, it can realistically check almost every combination and show you all of them.

Standard "My Dog Has Fleas" tuning gives the four strings — G, C, E, A — fixed pitch classes. For the chord you type, the tool parses the root and quality (major, minor, sevenths, sixths, ninths, suspensions, slash-bass chords and more) into a set of required notes, then works through every open, fretted, or muted choice on all four strings within the search window. A shape counts only if it sounds every required note and nothing outside the chord; if nothing fits near the nut, the window slides up the neck, fret by fret, up to the ninth fret.

Because four strings can't always hold every note of a bigger chord, the search follows the same shortcut a player would: keep the root, third and the defining upper extension, and drop the fifth first if a note has to go. Every match is scored on playability — muted strings count against it, open strings for it, and a wide stretch against it — then deduplicated and sorted, so you can page through the full list from most to least comfortable.

The diagrams follow standard chord-box notation, drawn left to right as G, C, E, A to match the way printed ukulele chord charts are read: vertical lines for strings, horizontal lines for frets, filled dots for fretted notes, O for open strings, X for muted ones, and a bar wherever one finger covers several strings at the same fret.
