Jay begins this episode with Paul Hindemith, who in 1921 combined his interest in ragtime with his love of Bach. There is also a minuet by Ravel, glancing back at Haydn. There is a song by Zemlinsky, setting Langston Hughes. There are wonders and curiosities in this episode—which, by the way, has a sponsor: Michael Lohafer, who, as Jay says, is “a particular authority on Mozart.” Mr. Lohafer says, “My sponsorship is on behalf of all attentive listeners to Music for a While who enjoy the well-considered selections that always delight the ear.”Bach, Fugue in C minor from “The Well-Tempered Clavier,” Book 1Hindemith, “Ragtime (Well-Tempered)”Ravel, “Menuet sur le nom d’Haydn”Schumann, “Faschingsschwank aus Wien”Zemlinsky, “Afrikanischer Tanz” from “Symphonische Gesänge”Liszt, “Canzonetta del Salvator Rosa” from “Années de pèlerinage, deuxième année: Italie”Vasks, Dolcissimo from “The Book”Prokofiev, Sonata No. 7, PrecipitatoMartinů, Fantasia for String Quartet, Oboe, Theremin, and PianoGounod, “Ah! lève-toi, soleil!” from “Roméo et Juliette”Tchaikovsky-Pletnev, Pas de deux from “The Nutcracker”
