Popoli di Tessaglia, K.316
Recitative and aria for soprano and orchestra
"Popoli di Tessaglia! – Io non chiedo, eterni Dei" (K. 316/300b) is a recitative and aria for soprano and orchestra that Wolfgang Amadeus Mozart wrote for Aloysia Weber. It is famous for including two occurrences of a G6, i.e. the G in altissimo above high C, or 1568 Hz by modern concert pitch – according to the Guinness Book of Records, the highest musical note ever scored for the human voice. (However, an A6 is scored in Ignaz Umlauf's Das Irrlicht, also sung by Aloysia Weber.)
