Péter Wolf's collection Wolf-temperiertes Klavier, published in 2018, referring to the series The Well-Tempered Clavier by Bach, contains 24 piano pieces, a major and a minor key composition based on each pitch of the chromatic scale. The ninth piece, an Adagio in E major, is one of the gems in the volume, building on the tradition of the Baroque pastorale. This soaring melody has been arranged by the composer to a duet: above the piano accompaniment, it can be performed by a violin or a flute (either by an oboe or other melodic instrument).
