LilyPond

Check out the LilyPond website, its tutorials, and such before you get too excited about this (you may want to learn the basics first). Nevertheless, a few of the basics are explained here. You'll need to install the program and get used to a text editor, the command prompt, and such too. I recommend SciTE as a text editor for LilyPond (User:Veramet can tell you how to configure it to compile and view the pdf, and play the midi from SciTE).

Comments

Everything on a line after a percentage sign (%) is a comment.
There is a lot of commented out code - uncommenting it will do different things to your music, unless the comment is there for documentation purposes.

First of all, type out your lyrics
- i.e. the first verse would be at the end of the section that starts with sopWords = \lyricmode; the second verse lyrics go in the section entitled sopWordsTwo = \lyricmode, and so on.
There are two things to uncomment, for each verse/stanza:
- %\context Lyrics = sopranos \lyricsto sopranos \sopWords
- %\new Lyrics = sopranos { s1 }

Write your lyrics in the section for those parts (you may have to create them if you have many verses).
Move the line that says %\new Lyrics = basses { s1 }, or such, to its proper position in the score: i.e. the bass section would go between 161 and 162 of your file.

Put the soprano part on line 127, the alto after line 133, the tenor after line 155, and the bass after line 160.

Well, this is an SATB template, but there are ways.
- If you want extra clefs and such, you may need a new template - or make a new one based off of this one.
- If you want it all on two clefs, just use notation for chords.
  - For a c major chord (with the duration of a quarter note), type the following in place of the notation for a note: <g' e' c'>4 (this could be put in the soprano section for three different soprano notes)
  - If you want polyphonic music (with moving parts) that has more than four parts, try the following <<{}{}>> (put the top notes, including durations, in the first set of brackets; put the bottom ones in the second; you can create a third set of brackets and so forth); putting two slashes (I forget whether they were forward or backward) between the sets of brackets will make the stem directions face different ways.
