What does transposing mean?

Transposing moves every chord up or down by the same musical distance. The progression keeps the same relationship between its chords, but the whole song sounds higher or lower.

Capo 4

Put your capo on fret 4.

Play chord shapes from G Major and they'll sound in B Major.

Why does a capo change the key?

A capo shortens every string at the same fret. Each fret raises your guitar by one semitone, so your familiar chord shapes produce higher notes without changing the shapes under your fingers.
