You might be wondering: why on earth would I choose a piece that is literally called "Dissonance" when I was looking for something a bit simpler or cleaner to talk about on the show today? Actually, Mozart's Dissonance quartet, probably his most famous and beloved quartet, was not called "Dissonance" by Mozart, and the rest of the piece is thought of as one of Mozart's most outgoing and cheerful works, though I think there's a bit more to it than that.

This quartet was part of a set of quartets dedicated to his friend and mentor Joseph Haydn, the father of the String Quartet. Upon their publication, Mozart wrote to Haydn: "Behold here, famous man and dearest friend, my six children. They are, to be sure, the fruit of long and arduous work, yet some friends have encouraged me to assume that I shall see this work rewarded to some extent at least, and this flatters me into believing that these children shall one day offer me some comfort."

The final one of this set of six quartets is the one we're going to talk about today, the one that has been dubbed "Dissonance." This single dissonance caused massive controversy in its time, which we'll get to later, but it is a fascinating insight into the rules of harmony at the time. Our sojourns into late Romanticism over the last few weeks, and especially my conversation with Case Scaglione about Wagner and the Tristan Chord, should help us understand the intensely heated debates that arose over that chord I just played you. So today on the show, we'll spend some time on that famous dissonance, then dive right into this glorious quartet, exploring Mozart's unparalleled ability to write the most glorious melodies and the most perfect harmonies.
