The five keys enable accidentals in the lower part of the instruments' range to be played dependably, and also serve for many higher notes. The 19-division equal temperament has applications both in the faithful reproduction of pre-nineteenth century tunings, and in new microtonal music. Notes See Barnes (2002).
