Transposer

A chart moved to another key, with the spelling that key actually uses rather than the nearest black note.

Write the chord symbols separated by spaces, one line per system if you like. Bar lines and repeat signs pass through untouched. Notes with an octave (C4, B♭3) are transposed too. The spelling comes out right: a tone above B♭7 is C7, and a tone above A♯7 is B♯7.
