Instantly transpose the chords of a song to different keys. It is often necessary to raise or lower the key of a song to suit a particular instrument or the vocal range of a singer. This can be a time consuming process and typically involves working out new chords and rewriting the songsheets. It is even more time consuming if you need to repeat the process to experiment with different keys. Stop wasting time, Instant Transposer makes it incredibly quick to change the key of a song as often as you like. It's really easy to use... Just type or paste-in a song and click a button to transpose. It will also convert chords both to and from solfege notation (Do Re Mi Fa = C D E F), another very useful feature because musicians tend to prefer one system over the other. Lyrics aren't affected, only the chords change.
