Here is a simple tool to help you change the key of a song, so that you can
- sing in a key that suits your voice (higher or lower), or
- play easier chords for guitar (music isn't always written for guitar, so the chords may be really awkward to play).
All you need is a copy of the song with the lyrics and the chords- there are dozens of sites on the internet which have these- and your Chord Transposing Wheel.
Click on the picture below to open the PDF file with the wheel to print and assemble, plus instructions for how to assemble and use your wheel.
