The inspiration for LilyPond came when two befriended musicians got annoyed with the bland and boring look of computer print-outs.
Every musician prefers reading beautiful music, so couldn't we programmers solve that printing problem? LilyPond just does that: it prints music in the best traditions of classical engraving with minimum fuss. Don't waste time on tuning spacing, moving around symbols, or shaping slurs. Impress friends and colleagues with sharp sheet music!
