{songs} is a package capable of producing songbooks.
The songs package is capable of producing songbooks with chords over the lyrics, songbooks with just lyrics, and sets of overhead slides for corporate singing. Chords can consist of chord names or guitar tablature diagrams but not full sheet music.
Lyric books, chord books, and slide sets are all generated automatically from a single master document. That way you can print lyric books for singers, chord books for musicians, and slides for the congregational singing, without having to maintain three separate documents. The documents produced by the software are typically in PDF format, but can be in any of the many electronic formats supported by LaTeX.
The CTAN version is outdated, check the package homepage for new updates.
