21st Century (2006). American composer Katherine Hoover. Movements entitled: What Goes Around for Alto Flute and Piano; Tango for Bass Flute and Piano. The composer hones in on some of the special but perhaps less commonly heard qualities of the alto andbass flutes. The alto has its lovely singing quality, but it also has the capacity to move quickly and easily, so the composer decided to feature that as well. The bass could show off that wonderful husky quality in a slightly off-center tango. -the composer
