How to transpose sheet music

Transposing moves a whole song up or down by the same distance. The melody and chords keep their relationships; only the pitch changes. You do it when a song sits too high or low for your voice, or when the original key is awkward on your instrument.

The half step is the unit

On a piano, the very next key (black or white) is one half step away. On guitar and bass, one fret is one half step. An octave has 12 half steps, so moving 12 brings you back to the same key.

GDE♭EFF♯A♭AB♭BC
DAB♭BCD♭E♭EFF♯G
AEFF♯GA♭B♭BCD♭D
EBCD♭DE♭FF♯GA♭A

Every key can be reached two ways: G to E is −3 or +9. Usually pick the smaller move.

What changes in chords and TAB

Chord names move by the same number of half steps: C–Am–F–G up two becomes D–Bm–G–A. The chord quality (m, 7, maj7…) never changes. Slash chords move both parts: G/B up two is A/C♯.

TAB numbers move too: up two half steps adds 2 to every fret. Numbers that would go below 0 or above the highest fret have to move to another string or octave, which is the tedious part to do by hand.
