Re: Help getting started - lilypond structure

[Joe Neeman]

This is a follow-up on the question of lilypond structure. Here is how I 
think a lilypond file is organised. It is fairly important that I get 
this right, because I am trying to rewrite the lily parser in denemo. 
Please correct me if I'm wrong.

A Voice consists of a sequence of notes and various other objects (like 
time signatures, etc). The notes are entirely sequential.

A \notes block consists of one or more Voice contexts. The Voices can be 
arranged sequentially or in parallel or a combination of both.

A Staff consists of one or more \notes blocks. The blocks can be 
arranged sequentially or in parallel or a combination of both.

A \score block consists of one or more Staves. The Staves can be 
arranged seqentially or in parallel or a combination of both.

Additionally, staves can be grouped (in parallel only) into Piano 
Staves, Grand Staves, Choir Staves and several other group types. These 
groups can be included in a \score block in the same way single staves are.

TIA,
Joe

PS, if I have "\notes{a4 b << {c d} {e f} >> }", then the {c d} by 
itself is a Voice context, right? And so is {e f}?
