The joy of ensemble playing with six hands at the piano is captured in this series of trios by educational music author Melody Bober. Written for pianists at the intermediate level, the pieces in this collection require reading notes above and below the grand staff, playing eighth-note scales in parallel motion, and playing in compound meter. Other challenges include eighth-note syncopations and occasional blocked octaves. Titles: A Chilly Nor'easter * Chromatic Waltz * El Matador * Riverbend Rag.
