How to transpose a song

  2. Press + or − until the song sits well in your voice.
  3. Pick sharps or flats, or leave Auto to follow the new key.

      

      
Questions

        
Why does a B♭ clarinet read a different note?
Its written C sounds as B♭, a whole step lower. So its part is written a whole step higher than concert pitch.

        
What does a capo do to the key?
Each fret raises every string by a semitone. G shapes with a capo on fret 2 sound in A.
