# life: Potus race, Kamala knows her jazz

<< 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. >>

<< The love of music is not necessarily an electoral strategy. But it would be interesting to find out which approach resonates most with voters ahead of the coming US election: scattergun and with no particular demographic focus, or targeted and consistent. >>

# 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. >>

# 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. >>

<< In a study appearing (..) in the The Astrophysical Journal, (AA) report (..) eight new echoing black hole binaries in our galaxy. Previously, only two such systems in the Milky Way were known to emit X-ray echoes. >>️

# brain: brain images of silence

<< When imagining music, the musicians' brain activity had the opposite electrical polarity to when they listened to it -- indicating different brain activations -- but the same type of activity as for imagery occurred in silent moments of the songs when people would have expected a note but there wasn't one. >>

<< There is no sensory input during silence and imagined music, so the neural activity we discovered is coming purely from the brain's predictions e.g., the brain's internal model of music. Even though the silent time-intervals do not have an input sound, we found consistent patterns of neural activity in those intervals, indicating that the brain reacts to both notes and silences of music. Ultimately, this underlines that music is more than a sensory experience for the brain as it engages the brain in a continuous attempt of predicting upcoming musical events. Our study has isolated the neural activity produced by that prediction process. And our results suggest that such prediction processes are at the foundation of both music listening and imagery. >> Giovanni Di Liberto.

# gst: immediate 'shot', the three second time window in art, music, poems and language processing

<< Is there a universal time constant for poetic lines when people read them aloud or recite them by heart? Turner and Pöppel (1988) collected over 20 types of poetry, varying from East to West and from modern societies to indigenous cultures, and found a constant of ~3 s for the duration of poetic lines. >>️

<< This observation indicates a production– perception synchrony of ~3 s, which means that we not only tend to recite poems  (and speech in a more general sense; discussed later) with a 3-s pattern but also appreciate poems aesthetically within the same temporal frame. This temporal preference for a 3-s pattern and not a 1-s or a 10-s pattern, which linguistically would be possible, indicates presumably a profound evolutionary basis. The temporal modulation effect of the 3-s window on aesthetic appreciation may also motivate to look for other concepts and phenomena of the cognitive and neural basis of aesthetic perception in general and in detail, as has been partly already done for decision processes, the visual arts, and music (Avram et al., 2013; Bao et al., 2016; Bao et al., 2017; Park et al., 2014; Park et al., 2015; Pöppel, 1989a). >>

# 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. >>

<< the patterns obtained from artificially designed out-of-equilibrium chemical oscillating networks (such as the Belousov–Zhabotinsky reaction for example) are unpredictable and difficult to control spatiotemporally, albeit reproducible over subsequent cycles. Here, (AA) show that it is possible to generate reproducible spatiotemporal patterns in out-of-equilibrium chemical reactions and self-assembling systems in water in the presence of sound waves, which act as a guiding physical stimulus. >>

# behav: adaptive synchronizations; the tendency to anticipate during auditory rhythms

<< Dancing and playing music require people to coordinate actions with auditory rhythms. In laboratory perception-action coordination tasks, people are asked to synchronize taps with a metronome. When synchronizing with a metronome, people tend to anticipate stimulus onsets, tapping slightly before the stimulus. The anticipation tendency increases with longer stimulus periods of up to 3500ms, but is less pronounced in trained individuals like musicians compared to non-musicians.  >>
