RICHARD: Well, I was appalled. Prague has played host to some of the greatest composers in history. Mozart named a symphony after it, for heaven’s sake. So what did I do?
EMILY: I have tried so hard to forget this.
RICHARD: I stood beside them and their boombox and I hummed Mozart’s Prague Symphony as loud as I could. [starts humming]
Symphony No. 38 in D major (K. 504), was composed by Wolfgang Amadeus Mozart, previously discussed, in late 1786. It premiered in Prague in 1787, during Mozart’s first visit to the city. Because of this, it is popularly known as the Prague Symphony. Mozart didn’t actually give it this name, and it’s not certain that Mozart wrote it in honour of Prague, although there is some evidence that he might have done.
