G'day,
There are words to thousands of songs, as you'll have discovered, more than half have tunes in MIDI format. Go to the bottom of the lyric and click on "Click here to play". You can download the MIDI instead of playing it if you like - right click on "Click here to play" and choose from the menu.

You can then use a notation program to print the music notation. Many Mudcatters use Noteworthy Composer which is inexpensive & can be downloaded from their web site click here.

Cheers,
Alan
