# gst: laminar and turbulent flows detected in music, a fluid framework approach

<< The relationship between musical material and physical phenomena has become a topic in the musicological literature over the last several decades, particularly concerning elements of the musical system itself, and constructions found in the work of contemporary classical composers such as Gyorgy Ligeti and Iannis Xenakis. Most scholars, who adopt this approach, explore the physical phenomena of fractals in the analysis of musical works, but fluid mechanical frameworks, such as laminar and turbulent flows, offer a new avenue to be explored. In this paper (AA) will propose a novel method of musical analysis for examining musical structures in terms of fluid-like behaviour such that Ligeti etude no. 9 serves as a model, whereby the metaphors of laminar and turbulent flows take precedence. >>

# gst: even a single bubble can produce creative musical outcomes

<< Producing original and arranging existing musical outcomes is an art that takes years of learning and practice to master. Yet, despite the constant advances in the field of AI-powered musical creativity, production of quality musical outcomes remains a prerogative of the humans. Here we demonstrate that a single bubble in water can be used to produce creative musical outcomes, when it nonlinearly oscillates under an acoustic pressure signal that encodes a piece of classical music. >>️

# gst: tuning to the edge of instability (in the cochlea)

<< Sound produces surface waves along the cochlea's basilar membrane. To achieve the ear's astonishing frequency resolution and sensitivity to faint sounds, dissipation in the cochlea must be canceled via active processes in hair cells, effectively bringing the cochlea to the edge of instability. But how can the cochlea be globally tuned to the edge of instability with only local feedback? >>

<< Surprisingly, (AA) find the basilar membrane supports two qualitatively distinct sets of modes: a continuum of localized modes and a small number of collective extended modes. Localized modes sharply peak at their resonant position and are largely uncoupled. As a result, they can be amplified almost independently from each other by local hair cells via feedback reminiscent of self-organized criticality. >>

<< However, this amplification can destabilize the collective extended modes; avoiding such instabilities places limits on possible molecular mechanisms for active feedback in hair cells. >>

AA << work illuminates how and under what conditions individual hair cells can collectively create a critical cochlea. >>️

<< a video showing Harris emerging from a record store in Washington DC has recently gained massive traction on social media. The footage, taken in May 2023, shows her engaging with journalists while displaying and talking about the records she had purchased. This video clip was notably shared and reposted among the European jazz community – not people you’d necessarily think would be hugely interested in the musical tastes of US presidential candidates. >>

<< Harris’s purchases included three classic jazz albums by notable African American artists: Charles Mingus’s 1972 album Let My Children Hear Music, Roy Ayers’ 1976 Everybody Loves the Sunshine, and the 1959 collaboration of Ella Fitzgerald and Louis Armstrong on Porgy and Bess. >>️

<< Liking and knowing jazz, in some circles at least, suggests sophistication, intellectualism, and a leaning towards advocacy for cultural unity through diversity. The improvisational and creative elements found in jazz might also translate to a degree of flexibility in her politics. >>

<< Un volo pindarico di sola chitarra, di poco meno di un minuto, che si libra tra i solchi incandescenti del secondo album, VAN HALEN II. La leggenda narra che, durante le registrazioni del disco, Eddie si fosse ubriacato una sera a casa del produttore Ted Templeman e si fosse messo a suonare una chitarra acustica. Sconvolto da ciò che stava ascoltando, Templeman decise di inserire quella perla nel disco in lavorazione. In quel minuto Eddie esegue una prova di virtuosismo che lascia senza parole: non è solo abilità tecnica, ma pura musicalità, con un groove che trasforma quella che poteva essere una semplice dimostrazione tecnica in una gemma autentica e compiuta. >>

# astro: eight new echoing black hole binaries (in Milky Way)

<< Scattered across our Milky Way galaxy are tens of millions of black holes—immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black holes are dark by definition, except on the rare occasions when they feed. As a black hole pulls in gas and dust from an orbiting star, it can give off spectacular bursts of X-ray light that bounce and echo off the inspiraling gas, briefly illuminating a black hole's extreme surroundings. >>

# behav: chaotic (jazz) music generated by songbirds during non-mating seasons for opioid reward

<< when songbirds sing during non-mating seasons, it's because singing releases an opioid naturally produced in their brain —that's right, a compound with the same biological makeup of the highly addictive painkillers. >> 

<< Animals—including birds, including humans—we produce our own endogenous opioids, and they reward behaviors naturally, like sexual behavior or feeding behavior, (..) Studies show that endogenous opioids also make play rewarding. Songbirds learn their songs, and must practice. When we listened to birds practicing in flocks, it almost sounded as if they were playing around with the notes. Darwin even suggested that birds in flocks may be singing for 'their own amusement.' So, we thought if singing is a playful behavior, it should involve opioids. >> Lauren Riters. 

<< in starlings, endogenous opioid-prompted song is evolutionarily advantageous, because singing in flocks allows them an opportunity to practice their song to prepare for the mating season. It might not be the most beautiful to listen to—Riters likened their chaotic song to freeform jazz—but that's okay. To them, it's just a warm-up for when they start looking for a mate. >>
