Jules Etienne Pasdeloup (1819–1887) conducted an orchestra in Paris for nearly three decades in the latter half of the nineteenth century and was a champion of controversial modern composers. He rehearsed his orchestra at the Cirque d’Hiver, an ornate Second Empire indoor amphitheater. Sargent, an ardent amateur musician, frequently attended Pasdeloup’s concerts and depicted them several times. This picture is his most abstract treatment of the subject and represents one of his boldest experimentations with Impressionism. The picture’s monochrome palette, painterly execution, and energetic composition suggest both the dance of musical notes across a page and the vital sound of the music itself.
