Software we made

Guitar Tab This is the TTF font we made for writing guitar chords in the music on this site. Upper case, A-J (keyboard middle row) for fingering, Z-M for a barre line, and the numbers.
Guitar Jar A really quick tool for working out guitar fingerings for a range of different types of chord. Might turn it into something bigger one day... Works on anything with Java.
