How do I work with the transposer?

Assume, that you have a song in ‘C’ and you need it two semitones higher: n- Move the lower ruler ‘C’ direct under the ‘C’ of the upper ruler n- Move the lower ruler two semitones to the left: Result is ‘D’ n- Look at your song and replace the note of every chord by the note of the lower ruler direct below. n- If there is a Fm in your song, replace it by Gm
