Using just 6 notes, Arco Echo explores G major in first position using only easy quarter- and half-note rhythms. A smooth detaché call-and-response between upper and lower string sections will help young students learn to listen across the ensemble, building confidence in simple three-part harmony with doubled Violin 2/Viola and doubled Cello/Bass. Optional piano is included for additional support, making this a fun first venture into independent counting.
