About Guitar Chord Assistant

What it is

Two tools for guitarists, free and with nothing to sign up for.

• Chord Finder — tap the notes you're holding on the fretboard and it tells you what chord that is, including slash chords when the bass note isn't the root.
• Chord Dictionary — pick a root and a quality and see every practical way to play it, from open position to the twelfth fret, with the fingering for each.

Why it exists

Most chord charts give you one shape per chord and leave you there. That's fine until you need the same chord somewhere else on the neck, or the printed fingering turns out to be one no hand can actually make. This site starts from the opposite end: show every voicing that is genuinely playable, then mark the handful worth learning first.

How the voicings are chosen

Every shape in the dictionary is checked against the chord's real note formula, so a Cm7 contains C, Eb, G, and Bb and nothing else. Shapes are then filtered by whether a hand can actually hold them — one finger per fret, a barre only across adjacent strings, the thumb only over the sixth string. Anything that fails is dropped rather than printed with a fingering nobody can use.

Out of what survives, a few forms per chord are marked as representatives: one or two per region of the neck, chosen for full sound and a grip you can reach. Those choices are made by hand, chord by chord, not by a formula.

How the diagrams work

Numbers on the dots are fingers — 1 is the index, 4 is the little finger, and T means the thumb comes over the top of the neck. A bar under several dots means one finger presses all of them at once. O above a string means play it open, X means don't play it, and (O) means it works either way. There's a fuller explanation in How to Read the Fretboard Diagrams.
