Transposing in Semitones
I am revisiting an old friend who is still proving a tough nut to crack: transposing in semitones. All seemed clear after mike320 posted as per image below but now I've got a bit confused again. From my guitar fretboard I can show that there are 12 semitone steps needed to move a note up by 1 octave. However, the table shown seems to show that there are 14 half steps. What am I missing?
