Are there difficult chords in a song? Or is the melody too high or low and it is not easy to sing it? This java applet helps you to transpose music and convert all chords into proper key. The applet direct transposes all common chords (tonic, dominant, subdominant, relative minor, minor 2nd, minor 3rd) and one selectable chord.
Original key is usually either the last or the first chord of the song.
The previous version of guitar chords transposition (java applet) is available too.
