Input (English): One of these compositions by George Rochberg includes a set of variations on Pachelbel's Canon in D, and Rochberg named his fourth through sixth works in the genre the "Concord" ones. The third movement of another piece for this ensemble explores what the composer called "dissonant dynamics," shaping a melody solely by changing the volume of various held pitches. That work is the best-known composition by Ruth Crawford Seeger. Irvine Arditti founded an ensemble of this type named after him, and another composition for this ensemble contains a Scherzo "alla bulgarese" flanked by two movements in its composer's (*) "night music" style. The performance of one of these pieces serves as the third scene of the opera Mittwoch aus Licht, and that piece requires that each of its performers be in a different helicopter. For 10 points, name this type of piece that might be performed by the Kronos, an example of which is Smetana's "From My Life."
