String Quartet String Quartet - Level 5 - Digital Download SKU: A0.966175 Composed by Joe Rosochacki. 20th Century,Contemporary,Jazz. Score and parts. 11 pages. Joe Rosochacki #2010093. Published by Joe Rosochacki (A0.966175). Originally a guitar piece, Potpouri lends itself to be a effective crossover as far as different ensembles are concerned. Aaron Copland and Lenoard Berstein rhythms, harmonizations permeate the work. This is comical jig, as the name imples, features mixed time signatures, hemiola (3:2), and reoccuring motives set in different tonic areas, etc. are some techiques used by me. This work is for advanced performers.
