Measures 1–9 of Fuga a 3 voci, BWV 847 by J.S. Bach (The Well-Tempered Clavier)

I nailed the Lilypond code from the LilyPond homepage. I ran the code through convert-ly which converted the file into a newer LilyPond version. I ran LilyPond on it, making a PostScript-file (.ps). I ran the ps through ps2ps, to render the notes in real paths and lines, instead of sheet-fonts. I converted the ps to svg using pstoedit. I fixed the image in Inkscape (removing all measures except 1-9), saving it as basic SVG.

The musical notation in this image was rendered by LilyPond, a free-software engraving program. Here is a listing of the LilyPond source used to create this file.

%{
 We really want this piece on 2 pages.

 tweaks:  we use 19 iso. 20 pt staff space, and squeeze up the spacing a bit.

 the few forced linebreaks were an earlier attempt to get the spacing
 to match up.
