(CD Sheet Music). CD Sheet Music(TM) is the revolutionary series of masterworks on CD- or DVD-ROM that transforms a PC or MAC computer into a virtual music library. Now you can quickly locate, view and print the great works of the classical repertoire. Compared to traditional printed sheet music or music downloads, it is incredibly inexpensive. Original sources are out-of-copyright standard editions from publishers such as Breitkopf and Hartel, C.F. Peters, G. Schirmer, Carl Fischer, G. Ricordi, Durand and many others. The discs also include biographical and analytical information from Grove's Dictionary of Music and Musicians , 1911 Edition. This is by far the largest collection of vocal methods and studies ever assembled, totaling over 3000 pages! Configured in alternate keys for all voice types, this CD includes works by Abt, Bona, Bordogni, Concone, Dannhauser, Labrache, Lamperti, Lutgen, Marchesi, Panofka, Shakespeare, Vaccai, Viardot, and more! A great reference with many unfamiliar works to explore.
