String Quartet String Quartet - Level 3 - Digital Download SKU: A0.690592 Composed by Jim Duff. Arranged by Jim Duff. Classical. Score and parts. 20 pages. Jim Duff #299299. Published by Jim Duff (A0.690592). An original composition for String Quartet. Begins with a Cello Ostinato, which is passed to the piano, while the Cello introduces the first melody above. The violin joins with melodic 16th note variations with the Cello melody. A new bridge section follows by the Piano without the Ostinato’s presence, with Bass accompaniment by the Cello. The Violin then joins the Piano in a kind of duet. A Dal Segno to the Sign follows for a repeat the original section followed by the ending at the Coda. This piece is a workout primarily for the violins, but is well worth the effort.
