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, has catalog numbers of H.484.1 or (-5[1])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,” 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” was the second son of J.S. Bach? ■END■ (10[2]0[2])
