"Duo Sonatina" is a three-movement piece for oboe and cello centered in the music of Brazil and Argentina. The first movement (Allegro) is set in traditional sonata form with two contrasting themes. The second movement, "Calmo" (Calm), features a poignant melody in the fashion of a Brazilian popular tune called "cantiga" (little song). The last movement, "Rondo-Tango," is full of virtuoso passages in the style of the Argentinean bandoneon player and composer Astor Piazzolla. Score and parts are included; duration 12 minutes.
