Duet No.1: Chorale Pointing Downwards is a work by contemporary composer Nico Muhly for Viola and Cello. The piece received its premiere at the Tenri Cultural Institute in New York in February 2004. Muhly himself writes of the work that it's the first in a series of short string pieces that serve simultaneous purposes as harmonic and technical studies for both composer and performers. Duet No.1 is constructed around a cycle of fourteen chords repeated almost without cessation. This drone-like cycle is subject to a few rhythmic alterations as well as two interruptions keeping thingsdynamic and exciting. The middle of the piece becomes in Muhly's words 'a sort of fervent perpetual-motion perseverance' in an attempt to combine harmonic beauty with what sounds like a musical exercise.

From 44 Duos For 2 Violins-Bela Bartók's 44 Violin Duos or selections therefrom have been the source of arrangements for a variety of instruments such as for piano (one set by the composer the Petite Suite) band as well as duos for every member of the string family even contrabass. These all followed the original concept: a pair of identical instruments. This set for viola and violoncello is intended to fill a gap where two instruments an octave apart can produce the broader tonal range. (P. Bartók)

These ten duets include works by Corelli Telemann Bach Handel Mozart and Schumann.

Elegy for viola and cello was written in April 1970 for Peter Mark and Geoffrey Rutlowski while the composer was guest professor at the University of California at Santa Barbara. Duration 8 minutes.
