A visual and musical expression of mathematical symmetry groups. The transformations done to the video are equivalent to the transformations done to the notes. These type of repeating patterns are called frieze patterns. A couple wallpaper groups are also represented.

Accuracy not guaranteed. Get Audacity and play! audacity.sourceforge.net Correction: it is the "Basilar" membrane, which is what I say, but somehow between recording the script and actually drawing the stuff I got confused and thought I just pronounced my Vs poorly. Always sad to have such a simple and glaring error in something I put hundreds of hours of work into, but a "Vasilar" membrane can be the kind that a Vi draws to explain Viola Vibrations, I guess! Making up new words is just so prolightfully awstastic. Props to my Bro for excellent and creative swing pushing, and to my Mamma for filming it. Extra special thanks to my generous donators, without whom I would not have been able to create this video. Because of your support, I have the equipment, time, and take-out Thai food necessary for doing stuff like this.

Correction: when I mark where pi is on the graph, I meant pi/2! Note: If this video were supposed to be teaching you, I'd probably have to make it boring and say that in one sense of limits, spoiler alert, you actually do approach a circle and a line, solving the apparent paradox by saying that the invariant of length does not hold over infinity. Luckily I am an artist, and this is a Rhapsody, and instead of "learning," you get to actually think, if you like.

Something a little different! Lyrics: You've taken the high notes right out of my life. You've taken the high notes right out of my life. You've taken my high notes and left me so damned low. You've taken the reds and the yellows right out of my life. You've taken the reds and the yellows, taken the reds and the yellows, right out of my life. You've taken my reds and my yellows and left me with nothin' but blues. You've taken the warmth right out of my life. You've taken the warmth right out of my life. You've taken my warmth and left me so damned cold. I used to be fast but now I'm slow, I used to be high but now I'm low, You've taken the high notes, you've taken the high notes. You used to keep me oh so warm with your frequently repeating form, But now I'm slow and low and cold and blue when I can't hold you. You've taken the high notes right out of my life. You've taken the high notes right out of my life. You've taken my high notes and left me... You've taken my high notes and left me... You've taken my high notes and left me so damned low.
