Examining Beethoven’s use of both consonance and dissonance can help us begin to understand how he added the unquantifiable elements of emotion and creativity to the certainty of mathematics.”Įxplained in words, Beethoven’s use of mathematics in his music may or may not seem easy to understand. By stacking the first, third, and fifth notes - D, F sharp, and A - we get a harmonic pattern known as a triad.” These three frequencies together create “‘consonance,’ which sounds naturally pleasant to our ears. “The first half of measure 50 of ‘Moonlight Sonata’ consists of three notes in D major, separated by intervals called thirds that skip over the next note in the scale. “A standard major or minor scale uses 8 of these keys with 5 whole step intervals and 2 half step ones.” So far, so good. “The standard piano octave consists of 13 keys, each separated by a half step,” St. Clair’s other vides: The Unexpected Math Behind Van Gogh’s “Starry Night.”) Clair which explains, using the example of the “Moonlight Sonata,” what the formidable composer did it using math. But why? Do their musical compositions have some underlying quantitative appeal? And by the way, “how is it that Beethoven, who is celebrated as one of the most significant composers of all time, wrote many of his most beloved songs while going deaf?” The question comes from a TED-Ed segment and its accompanying blog post by Natalya St.
