Capo Reverse Finder
For any target chord, list every capo fret and easier shape that produces it.
Overview
The capo reverse finder solves a question every guitarist eventually asks: "I need to play this chord, but the open-position shape is awkward. Where do I put the capo, and what easier shape can I use instead?" Type in the target chord (say, B major) and the tool lists every fret where a capo lets you finger an open-position shape that sounds as B.
It's especially useful for singer-songwriters working out keys that fit their voice, worship leaders adapting lead sheets on the fly, and beginners who want to play recorded songs without grinding through barre chords. The same logic helps you transpose a whole progression to a friendlier shape set without changing the song's actual pitch.
How it works
A capo raises every open string by a fixed number of semitones, so a chord shape played behind a capo sounds higher than the same shape played open. If you want to sound a B major chord, you can use a C-shape with the capo on fret 11, a D-shape on fret 9, a G-shape on fret 4, an A-shape on fret 2, or an E-shape on fret 7. The tool walks every common open-position root (C, A, G, E, D, and their minor variants) and computes which fret produces the target chord.
Practically, you pick the lowest-fret option that still keeps your other chord shapes playable. Most songwriters cluster their capo around frets 2 to 5 because that's where the neck is comfortable and the tone stays open and ringing.
Examples
Target: F major → E-shape capo 1, D-shape capo 3, C-shape capo 5
Target: B major → A-shape capo 2, G-shape capo 4, E-shape capo 7
Target: Eb major → D-shape capo 1, C-shape capo 3, A-shape capo 6
Target: C# minor → Am-shape capo 4, Em-shape capo 9
FAQ
Does using a capo change the song's key?
No. The pitches you hear are determined by where the capo sits plus the shape you play. The tool keeps the sounding key constant and just offers easier fingerings.
Will the shape sound exactly the same as the original chord?
The pitches will match, but the voicing (which note is on top) and the tone will differ slightly because open strings ring above the capo. Many players love that ringing quality.
What if I want to keep the song in the original key but play different shapes?
That's exactly what this tool gives you. Pick any fret-and-shape combination from the list; they all sound as the target chord.
Can the capo go above the 12th fret?
Mechanically yes on most guitars, but tone and intonation suffer. Stick to frets 1-7 for the best balance.
