This is the most serious and useful collection yet published of solo arias from oratorios, masses and cantatas. The literature was confined to work by major composers, and by-passes the dated oratorio literature found in previous collections. The most famous music is here, and so is interesting and less famous music by masters. There are new music engravings for each aria, and extensive historical notes and translations. Solo instrumental obbligato parts, which can be cut from the book, are included on appropriate selections.
