||This is the Viola book for the series. For any of the other books type the instrument name. (Violin, Cello, Flute, Clarinet, Saxophone or Horn) Two books with each order. A set of short duos at an upper-intermediate level in a modern idiom. Many of the duos use mixed meter, modes and dissonance. These pieces were designed to be used in the studio for teacher & student, or two students on the same instrument. To increase the usability of the pieces they can also be used by pairs of different instruments as is indicated on the title page of each duo.
