Instrumental Duet Instrumental Duet,Viola,Violin - Digital Download SKU: A0.921969 By Kacey Musgraves. By Kacey Musgraves, Natalie Hemby, and Shane McAnally. Arranged by Krista Broadway Swider. Country. Score and parts. 7 pages. Krista Swider #5954823. Published by Krista Swider (A0.921969). In this sweet ballad to the human race, Kacey Musgraves brought simple soothing harmonies and a sparkling melody to life with her original, arranged for voice and piano.  In this challenging arrangement for violin and viola, I've replaced the piano part with rich chords in the viola (with an occasional dabble in the melodic line), and the playful, lyrical melody of the voice in the violin part. A simple, country/pop ballad sparkles in this string duo.
