Transpose B Major to B♭ Major

Every chord moves 11 semitones up (the same as 1 down). B♭ Major sits below B Major here, so a capo cannot make this move — you need the chart rewritten.

How to transpose from B Major to B♭ Major

By hand, in five steps — or in one click at the bottom of this page.

  1. 1Work out the distance: B Major to B♭ Major is 11 semitones up, or 1 semitone down — the same destination either way.
  2. 2Move every chord root by that distance. B Major's home chord becomes B♭, and every other chord shifts by exactly the same amount.
  3. 3Keep each chord's quality untouched. A minor chord stays minor, a 7th stays a 7th — only the root letter moves.
  4. 4Respell the accidentals to match the destination key. B♭ Major carries 2 flats, so write the notes the way that key spells them.
  5. 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 11 semitones and keep the chord's quality as written.

Frequently asked questions

How many semitones from B Major to B♭ Major?
11 semitones up, which is the same as 1 semitone down — you land on the same chords either way, just in a different octave.
What do the chords become?
B becomes B♭, C♯m becomes Cm, D♯m becomes Dm, E becomes E♭, F♯ becomes F, G♯m 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 B 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 B Major?
No — B♭ Major is the harder of the two (3.67 against 3.5), so expect more barre chords. A capo is worth considering.

Do it to the whole chart

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 B Major to B♭ Major in place — same layout, same spacing, print-ready.
