6(Ensemble Collection). A wonderful compilation of duets from Rubank, the two volumes presented here supplement musical development and provide a rich experience for growing musicians. Duet playing is often a student's first form of ensemble experience - technique, tone quality, intonation and balance are introduced as students do one of the things they enjoy most - making music with a friend. And duet playing leads easily and naturally to competent performance in larger ensembles. (Vol. I Easy to Medium, Vol. 2 Advanced)
