Nocturne in D-flat major, opus 27 no. 2, by Fryderyc Chopin, performed by Robert Helps, accompanied by a graphical score. FAQ
Q: What do the colors indicate? A: In this video, color is used to indicate the types of interval between notes that are sounding (or were recently sounding). The most consonant intervals are given subdued colors (blues and greens), and the most dissonant intervals are shown in brighter colors (orange, red, yellow).
Q: Where did this recording come from? A: The Special Collections at the library of the University of South Florida include the Robert Helps Papers, which includes many recordings. This recording was made at a faculty recital held on October 6, 1982. You can read about the collection here: http://www.lib.usf.edu/aeon/eads/inde... (The item containing this recording is listed in BOX 89.)
Q: Why so many versions of this piece? A: I posted the first version a long time ago, when YouTube's video resolution was very low. When they increased the resolution, I re-did so that it would be clearer. I didn't like the recording I used, though, and I planned to practice the piece and do another version, but then I was given permission to use the recordings in the Helps collection, and decided to use his. Another reason to give it another try was that I improved the visualization a little.
