Miklos Spanyi is recording this composer’s complete works for his instruments. It’s not Elliott Carter, but this composer wrote a late E-flat major double concerto for piano and harpsichord. A concerto by this composer beginning on tutti “A C E low E F” has versions for flute, piano, or cello. This composer’s most popular flute concerto, in D minor, (15[1])has catalog numbers of H.484.1 or Wq 22. Mozart’s remark that this composer “is the (*) father. We are the children” likely refers to his Versuch on piano technique and not his Empfindsamer Stil. As the court’s keyboard player, this composer possibly wrote a theme beginning “C E-flat G A-flat low B-natural,” (-5[1])upon which The Musical Offering was written after Frederick the Great asked his father to improvise on it. For 10 points, what composer of “Solfeggietto” (10[1])was the second (10[1])son of J.S. Bach? ■END■ (10[2])
