Weekly Music Theory Challenge 6/7/21

Show off your theory chops with my weekly challenge! You’ll find a new question here every Monday. Please comment to post your reply.

This week’s challenge:

These are the octaves that open Beethoven’s last piano sonata, Opus 111 in C minor. What interval do they form, and what interval is enharmonic with this one?

Listen to the Audio:

Check back Friday, June 11th for the answer!

ANSWER for 6/7/21

This is a diminished seventh. It’s enharmonic with a major sixth, but the spelling of E flat down to F sharp makes it a seventh. Letter name spelling always determines what an interval is called. When naming an interval, always start with letter names before considering the flats and sharps. Any kind of E (E natural, flat, or sharp) down to any kind of F is a seventh. Then look at the number of half-steps in the interval. A major seventh is eleven half-steps, a minor seventh is ten, and a diminished seventh is nine. It sounds the same as a major sixth, but spelling is everything! It determines not only the interval’s name, but also how it functions in music.
