Abe Torchinsky (1920-2009) - former principal tubist of the Philadelphia Orchestra - produced this important series of orchestral study books for tubists. In these books every tuba part is reproduced in its entirety. Drawing on his years of experience, Torchinsky's text is clear and concise concerning each work-noting the difficulties in the music and offering advice to tubists. Many errors in the original parts have been noted with corrections in these books. This edition, printed by Amazon, is exactly the same as the U.S. edition but is not spiral bound. This book contains tuba parts to Mahler Symphonies 7, 8, and 9.
