The composer Ernest Bloch was born in Switzerland, and after spending time in America, he was thinking of returning to Europe. But a visit in 1922 to the Library of Congress, in Washington DC, convinced Bloch to stay in this country, and to take American citizenship.

Imagine, for a moment, Mozart walking down Broadway, in New York City. It’s not so easy. But Lorenzo da Ponte, who wrote the librettos for Mozart’s operas Don Giovanni, The Marriage of Figaro, and Così fan tutte, died a New Yorker.

Prokofiev visited America a number of times, and his concerts here were extremely successful. His opera The Love for Three Oranges was premiered in Chicago, and he met his first wife, the soprano Lina Llubera, in New York City.

As a young man, Ernest Chausson studied law, and was admitted to the bar. But music was his great love, and instead of practicing law he enrolled at the Paris Conservatory.

No piece of music is ever just “about” any one thing. In Mozart’s opera Don Giovanni, Don Giovanni stands beneath Donna Elvira’s window and sings the aria Deh vieni alla finestra, “Come to the window, O my treasure.” It’s a serenade, a love song, and a very beautiful one. But there’s one big problem: it’s a fake.

The da capo aria, which I talked about yesterday, was a form that by 1750 had begun to lose its once enormous popularity. It was a form that was essentially killed by excess. The reign of the da capo aria coincided with the reign of the castrati as the stars of Italian opera.

For about a hundred years, roughly from 1650 to 1750, the principal type of aria in opera, and also in the oratorios and cantatas of such composers as Bach and Handel, was the da capo aria.

The aria - a musical form that’s a kind of song, but more elaborate and vocally demanding than the pieces we usually call songs. The development of opera in Italy in the 1600's is what brought the aria to glory.

Arias are the pieces for solo voice with instrumental accompaniment that are found in operas, oratorios, and cantatas. They’re songs, in a sense, but they tend to be more musically elaborate and vocally demanding than the kinds of pieces we usually call songs.

Acoustics is the science of sound, but the word also refers to the qualities of a room—the qualities that determine and describe how things sound in that room.
