A complete reference guide which comprises all the historical, literary, mythological and religious subjects found in vocal and instrumental works. Approximately 1500 subjects appear in alphabetical order. Every single entry presents a concise introduction in which historical references and important literary adaptions are presented.

This is an all-inclusive lexicon taking not only vocal and instrumental works into account, but also lost, unpublished and fragmental pieces.

Among the features of this expansive two volume set are:
- Over 17,000 subject-related compositions scanning five decades
