Zooming along

Back in the 1980s, it took immense amounts of computer time to generate fractal images. If you wanted to see pretty pictures of recursively-generated figures, you borrowed books such as The Beauty of Fractals, or watched Nothing But Zooms if you knew someone with the video. Computers and software have come a long way since then, and nowadays you can easily create your own fractal images on your laptop. I experimented with a couple of applications for Macs this weekend, Xaos and UltraFractal.

Xaos is freeware, and it comes in Windows and Linux versions as well. It’s fairly easy to use, though you might want to bookmark the online documentation. It’s what I used to make the video above. It doesn’t actually make movies. Instead, it outputs a series of .png files, which you can import into Final Cut or something similar. (Be aware that at 30 frames per second, there are 1800 images per minute. You’re going to be working with a lot of files.)

Ultra Fractal has some Photoshop-style image manipulation features. It’s more complicated than Xaos but not really difficult to figure out. However, it’s a bit pricey; if you want to do animations, it will cost you $130. I think I’ll make do with Xaos for now.

Vexed

There are all kinds of strange things on YouTube. For instance, this recording of Erik Satie’s notorious “Vexations.” Normally a complete performance runs from 14 to 24 hours. Nicholas Horvath plays the 840 repeats in less than ten hours, which is blazingly fast for a piece marked “très lent.” (No, I’m not counting them, and I don’t expect to listen to the whole thing.) On another occasion, Horvath took 35 hours to play the piece. That performance was probably closer to the proper tempo.

Not every pianist who attempts a solo “Vexations” succeeds. From The New Yorker:

An Australian pianist named Peter Evans abandoned a 1970 solo performance after five hundred and ninety-five repetitions because he claimed he was being overtaken by evil thoughts and noticed strange creatures emerging from the sheet music. “People who play it do so at their own peril,” he said afterward.

Arriving at Harmony Row

I early acquired the habit of listening to music from the bottom up. A tune with an energetic bass line is far more likely to catch my attention than one in which the bass merely marks chord changes. I took to Cream immediately, partly because of Clapton and Baker, but mainly because of bassist, singer and songwriter Jack Bruce. There are many musicians whose bass playing I’ve enjoyed, but Bruce has always been my favorite.

Jack Bruce passed away today. R.I.P.

Here’s Bruce with Ginger Baker and Eric Clapton:

Seeing red

Is She U.N. Owen?” is probably the best-known piece of music from the vast Touhou Project, ((except possibly for “Bad Apple“)) and you can find innumerable versions in every style, from orchestral to nightcore, on YouTube. I stumbled across the one above recently while looking for something else.

Another version of the tune, impressive yet ridiculous.

Incidentally, “U.N. Owen” is not “Death Waltz.” This is “Death Waltz:”

Update: Yet another version of “U.N. Owen,” this one by Floating Cloud.

Roger

My friend Roger, musician and aficionado of fine anime, acquired another fiddle for his collection Friday in the old-time fiddle competition at the Walnut Valley Festival in Winfield, Kansas.

This was his encore:

Rock and reel

When does a fiddle contest require a referee?

(Translation of the text at YouTube via a friend: “Annual competition in Pembroke which has about 25 fiddlers playing reels in turn without stopping and without playing a reel that has been played before. Towards the end, the fiddler must play only the “A” of a reel (which only lasts 10 seconds). This video shows the final minutes of the contest Sep 5, 2010, while there were only three participants. April Verch, Shane Cook and Danny Perreault. The contest lasted about two hours. Judge: René Dacier. Winner 2010: April Verch. In the end, Danny Perreault played one of his compositions (Breakdown at Rosary) and Germain Leduc accompanies on the piano in a funny way …”)
