Transpose C Major to B♭ Major
Every chord moves 10 semitones up (the same as 2 down). B♭ Major sits below C Major here, so a capo cannot make this move — you need the chart rewritten.

How to transpose from C Major to B♭ Major
By hand, in five steps — or in one click at the bottom of this page.
- 1Work out the distance: C Major to B♭ Major is 10 semitones up, or 2 semitones down — the same destination either way.
- 2Move every chord root by that distance. C Major's home chord becomes B♭, and every other chord shifts by exactly the same amount.
- 3Keep each chord's quality untouched. A minor chord stays minor, a 7th stays a 7th — only the root letter moves.
- 4Respell the accidentals to match the destination key. B♭ Major carries 2 flats, so write the notes the way that key spells them.
- 5Check any bass note written after a slash, and any chord borrowed from outside the key — those move by the same distance as everything else.
Every note, transposed
Charts wander outside the key all the time — a passing major chord, a borrowed minor, a slash bass. Use this chromatic map for anything the table above does not cover: shift 10 semitones and keep the chord's quality as written.

Frequently asked questions
- How many semitones from C Major to B♭ Major?
- 10 semitones up, which is the same as 2 semitones down — you land on the same chords either way, just in a different octave.
- What do the chords become?
- C becomes B♭, Dm becomes Cm, Em becomes Dm, F becomes E♭, G becomes F, Am becomes Gm.
- Can I use a capo instead of transposing to B♭ Major?
- Not directly. A capo can only raise pitch, and B♭ Major sits below C Major in this direction, so you would need to rewrite the chart — or capo up to reach it from an octave below, which is rarely practical.
- Is B♭ Major easier to play than C Major?
- No — B♭ Major is the harder of the two (3.67 against 2), so expect more barre chords. A capo is worth considering.

Rewriting chords by hand is slow and easy to get wrong halfway down page two. Upload the PDF or a photo of your chart and every chord moves from C Major to B♭ Major in place — same layout, same spacing, print-ready.
