Chord transposer
Paste chords or a lyric sheet with chords, then shift the key. Lyrics stay put; only the chords move.

When to transpose
The most common reason is voice range: if the chorus is too high, drop the song two or three semitones. The second is playability: songs in E♭ or B♭ are awkward on guitar, so guitarists transpose to G or C shapes and add a capo to get back to the original pitch. First chord shapes used by the capo helper: G = 320003C = x32010D = xx0232.

Questions
How do I transpose chords?
Move every chord root by the same number of semitones. Up two semitones turns G–C–D into A–D–E. The chord quality (m, 7, sus4…) never changes, only the letter.
What format does the transposer accept?
Standard chord-over-lyric sheets (a line of chords above each lyric line) and inline ChordPro-style brackets like “[G]Amazing [C]grace”. Lyric lines are left untouched.
How does a capo change the chords?
A capo raises every string, so the shapes you play sound higher. To play a song in B♭ with G-shape chords, put the capo on fret 3 (G + 3 semitones = B♭) and play the shapes transposed down 3.
Should I use sharps or flats?
Use whatever the target key normally uses: flat keys (F, B♭, E♭, A♭, D♭) are written with flats; sharp keys (G, D, A, E, B) with sharps. Auto mode keeps each chord’s original spelling style.
