These volumes are designed to help you more fully prepare for orchestral auditions and performances. The process involves de-constructing the materials to the most basic playing principles and then gradually reapplying the complexities on a better foundation. The exercises are extraordinarily useful even if you are not preparing an audition.These books represent McGregor's thirty-five years of experience at the major orchestra level (Baltimore Symphony, eleven years; Los Angeles Philharmonic, twenty-four years).A major pedagogical triumph, ...a giant step beyond conventional excerpt books, ...a gold mine, ...he literally encircles and traps each of the Audition excerpts, leaving it no way out but the right one. And sometimes he plays with it like the cat with the mouse. Volume III Bach: Mass in B minor (Credo); Bartók: Concerto for Orchestra; Debussy: Images; Mahler: Symphony No. 5; Rimsky-Korsakov: Scheherazade
