David Bowie's Hair Might Fetch More Than $4000 at Auction This Weekend

When he died from liver cancer last January, David Bowie’s net worth was estimated at $100 million—and that wasn’t even including his hair. Now, a lock of the late English singer and songwriter’s blonde mane is expected to sell at auction this Saturday for more than $4000, the Associated Press reports.

Beverly Hills auction house Heritage Auctions is in charge of selling the valuable snippet. Bidding starts at $2000, but sellers say they’re anticipating a much larger sum. A portion of those proceeds will go to a good cause: The Soi Dog Foundation, a dog and cat rescue organization in Thailand.

The clip of Bowie’s tresses is approximately 2 inches long, and tied together with blue thread. It was cut from his coiffure when a woman who made wigs for wax figurines at Madame Tussauds in London was tasked with replicating Bowie’s signature 1983 'do for a figure being created for the museum. She took a hair sample from the singer to match its exact color, and kept it as a souvenir. Today, it’s affixed to the upper left corner of a black-and-white framed photograph of her and Bowie. (The relic comes with a signed letter from the wig-maker explaining the hair snippet’s back story.)

Surprised that anyone would actually shell out more than $4000 for a lock of a singer’s hair? You shouldn’t be. All celebrities have to do is touch (or even breathe on) an object for it to fetch big bucks at the auction block.

Case in point: Scarlett Johansson’s used tissue, which she blew her nose with while appearing on The Tonight Show with Jay Leno in 2008, raised more than $5000 for charity. And in 2004, a piece of Britney Spears’s used gum, which she spat out backstage at a Toronto concert, reached a hefty $14,000 in eBay bidding. We’re not sure what someone would do with any of these items, let alone Bowie’s hair—put it under a glass case, or weave it into Victorian-inspired mourning jewelry, perhaps?

New AI-Driven Music System Analyzes Tracks for Perfect Playlists

Whether you're planning a bachelorette party or recovering from a breakup, a well-curated playlist makes all the difference. If you don't have time to pick the perfect songs manually, services that use the AI-driven system Sonic Style may be able to figure out exactly what you have in mind based on your request.

According to Fast Company, Sonic Style is the new music-categorizing service from the media and entertainment data provider Gracenote. There are plenty of music algorithms out there already, but Sonic Style works a little differently. Rather than listing the entire discography of a certain artist under a single genre, the AI analyzes individual tracks. It considers factors like the artist's typical genre and the era the song was recorded in, as well as qualities it can only learn through listening, like tempo and mood. Based on nearly 450 descriptors, it creates a super-accurate "style profile" of the track that makes it easier for listeners to find it when searching for the perfect song to fit an occasion.

Playlists that use data from Sonic Style feel like they were made by a person with a deep knowledge of music rather than a machine. That's thanks to the system's advanced neural network. It also recognizes artists that don't fit neatly into one genre, or that have evolved into a completely different music style over their careers. Any service—including music-streaming platforms and voice-activated assistants—that uses Gracenote's data will be able to take advantage of the new technology.

With AI at your disposal, all you have to do as the listener is decide on a style of music. Here are some ideas to get you started if you want a playlist for productivity.

Stradivarius Violins Get Their Distinctive Sound By Mimicking the Human Voice

Italian violinist Francesco Geminiani once wrote that a violin's tone should "rival the most perfect human voice." Nearly three centuries later, scientists have confirmed that some of the world's oldest violins do in fact mimic aspects of the human singing voice, a finding which scientists believe proves "the characteristic brilliance of Stradivari violins."

Using speech analysis software, scientists in Taiwan compared the sound produced by 15 antique instruments with recordings of 16 male and female vocalists singing English vowel sounds, The Guardian reports. They discovered that violins made by Andrea Amati and Antonio Stradivari, the pioneers of the instrument, produce similar "formant features" as the singers. The resonance frequencies were similar between Amati violins and bass and baritone singers, while the higher-frequency tones produced by Stradivari instruments were comparable to tenors and contraltos.

Andrea Amati, born in 1505, was the first known violin maker. His design was improved over 100 years later by Antonio Stradivari, whose instruments now sell for several million dollars. "Some Stradivari violins clearly possess female singing qualities, which may contribute to their perceived sweetness and brilliance," Hwan-Ching Tai, an author of the study, told The Guardian.

Their findings were published in the journal Proceedings of the National Academy of Sciences of the United States of America. A 2013 study by Dr. Joseph Nagyvary, a professor emeritus at Texas A&M University, also pointed to a link between the sounds produced by 250-year-old violins and those of a female soprano singer.

According to Vox, a blind test revealed that professional violinists couldn't reliably tell the difference between old violins like "Strads" and modern ones, with most even expressing a preference for the newer instruments. However, the value of these antique instruments can be chalked up to their rarity and history, and many violinists still swear by their exceptional quality.
