How quick is entering music with LilyPond?
There is no single answer to this, as the time spent depends on the complexity of the music, and your fluency in LilyPond. Music with complicated constructs (cross-staff beaming, collisions) takes longer to enter than simple monophonic music. Experienced users have reported average times of 3.5 pages per hour for typing straightforward music monophonic with an editor only. This time includes corrections and minor layout tweaks.
