Incredible slo-mo video of raptors flying through bubble clouds… for science

How does an owl’s tail help it fly? To understand the role of the tail is raptor aerodynamics, researchers at the UK’s Royal Veterinary College recorded the motion of tiny helium bubbles as they were swirled about by birds of prey flying through them. According to the science journal Nature, the videos enabled the scientists to discover “a new way in which birds use their tail to provide lift and so reduce drag while gliding… Their findings could provide a new way to improve the efficiency of small gliding aircraft.”

I found this thread on Twitter pretty funny, where writer Nicole Najafi imagines what dates might be like with all of the Democratic candidates.

I went on a date with every presidential candidate so you don’t have to. (thread 1/9) pic.twitter.com/v9Ou5eGcwn

An interview with legendary bass player Carol Kaye

On Legs McNeil’s Please Kill Me, Michael Shelly interviews the legendary bass player, Carol Kaye. Unless you’re a hardcore music nerd, you may not know who Carol Kaye is. You need to fix that.

Carol Kaye is the bassist on thousands of 20th century recordings, from The Beach Boys’ Pet Sounds to Nancy Sinatra’s These Boots are Made for Walkin’, to Glen Campbell’s Wichita Lineman. Oh, and she also played on the Mothers of Invention’s Freak Out! and the Batman theme song. The list goes on and on and on.

Get this woman into the Rock & Roll Hall of Fame, stat!

PKM: When producers, like Brian Wilson with “Good Vibrations,” would do a single song in parts over many sessions was that frustrating or fun for you?

Carol Kaye: You know Brian was a nice young kid. We worked for a lot of those young guys back then and Brian had something special about him, and he grew with every date. You saw his talent getting better and better and better. He’d only do one song for a three-hour date and that does get boring after a while, but he would come in and he’d give you this handwritten, kind of funny sheet music with stems on the wrong side of the notes and sharps and flats everywhere. He would sit down at the piano and play the song, to kind of give us a feel for it, and then he’d go in the booth and take charge from there. I never knew he played bass until a lot later because he never told me he played bass, I thought he was a piano player. But he wrote the bass parts out because he had certain parts that he wanted to jibe together and he heard these sounds. I think it was because of his fascination with The Four Freshmen. Brian heard music in a different way. He was a nice young man who had a sense of humor and everything he touched was a hit. And the Beach Boys were never there. They’d come in and say hello for five minutes and then walk back out, but Brian was in charge of it all, so he was a sharp young guy.

PKM: So the job as you’re describing it was to make the song happen whether it was inventing your part or cold reading notes or somewhere in between, and bass is interesting because some non-musicians don’t even know the bass does, they can’t even identify it, but it can really affect a song.

Carol Kaye: The bass is the foundation, and with the drummer you create the beat. Whatever you play puts a framework around the rest of the music, and Brian Wilson was bass conscious. Sometimes he’d have a string bass playing along with me, mixed so that you never heard it too much, but you felt it there. Another date with the string bass was “Boots” by Nancy Sinatra. That was kind of a throwaway tune, the last tune of the three-hour date. Lee Hazlewood in the booth said to Chuck Berghofer, the string bass player, to play a line like (Carol hums a slow descending bass line), so that’s what Chuck did. Lee stopped him and said “No, no. Make them closer together.” So that’s what you hear when you hear that bass go (Carole hums the famous bass intro to “These Boots Were Made For Walking”), and then I’m joining in at the bottom. We went to the next date and didn’t think a thing about it, and that darn thing was a big hit.

Read the rest.

Here is a short YouTube introduction to Ms. Kaye.

Classical guitarist built a microtonal guitar from LEGO and it sounds beautiful

Most Western music is based on a twelve-tone octave with the smallest interval being a half step (or half tone, or “semitone”) up or down. Microtonal music contains intervals smaller than a semitone. (Imagine playing notes between the keys on a traditional piano.) You can hear microtonal music compositions in the work of modernist and experimental composers, from Charles Ives and Claude Debussy to Wendy Carlos and Aphex Twin.

Tolgahan Coğulu is a Turkish musician known for designing an adjustable microtonal guitar and performing unique arrangements of Anatolian folk music and Ottoman maqam music. Most recently though, he took a cue from his young son and built a fantastic microtonal guitar from LEGO!

Video of incredible planetary system created from paint, oil, and soap

French video artist Thomas Blanchard created “Mini Planets” by mixing paint, oil, inks, and soap to stunning effect. It reminds me of the psychedelic alternate universes manifested in the 1960s liquid light shows. Blanchard writes:

The visual compositions have been created out of paint, oil, inks and soap. All videos were filmed in 8K with the RED Helium camera with 100 mm L macro lens Canon and MPE 60 mm macro lens Canon. The editing of the video is in 4K.
