Dblatex does not itself present musical notation. Of course, images of musical scores can be incorporated into dblatex output as can any other sort of images. For a more comprehensive solution which better integrates the typesetting of text with musical notation the LilyPond project (http://www.lilypond.org/) provides a facility for including musical notation within DocBook documents. LilyPond provides a program, lilypond-book, that pre-processes DocBook documents containing LilyPond musical notation and which can automatically invoke dblatex to produce PDFs integrating musical notation with text.

Information regards lilypond-book is, at present, found in LilyPond's “Usage” manual, the “Running lilypond-book” chapter, the “Integrating music and text” section.
