This is guitar tab for a song called 3 Gene. Tab is a map for the hands. The six lines are the six guitar strings. A number on a line tells you which fret to press on that string.
The buttons at the top turn each part on or off: two guitars, bass, and the Lead Solo (recovered) we pulled back from the recording. Press Play to hear it with a marker following along.
We made this so you can read the music in a web page, with no special app to install.
