of Dresden Concerti (Seibel 204, 208, 211, 213–215, 217, 226, 231–235, 240), followed by a recording of Heinichen's Lamentationes and Passionsmusik (1996). His sole opera for Dresden, Flavio Crispo (1720), was never performed and was not recorded until 2018. Two "passion oratorios", L'aride tempie ignude (1724?) and Come? S'imbruna il cieli Occhi piangete (1728) (classified in the catalogue as the cantatas Seibel 29 and 30), were recorded in 2021 by the Kölner Akademie. Circle of fifths Heinichen is credited with independently inventing the circle of fifths (German: Musicalischer Circul) in his Neu erfundene und gründliche Anweisung (1711), though he was not the earliest inventor. The circle of fifths had previously been invented by Nikolay Diletsky in the late 1670s (of which Heinichen was unaware). Heinichen credited Athanasius Kircher as a predecessor, specifically his Musurgia universalis (1650). Works list References Further reading Buelow, George J. 1966.
