A complete invariant for doodles on a 2-sphere
We define a complete invariant for doodles on a 2-sphere which takes values in series of chord diagrams of certain type. The coefficients at the diagrams with $n$ chords are finite type invariants of doodles of order at most $2n$.

Been hunting for this beauty of a track for almost a year now, after hearing it (uncredited) in a mix... 10 mins of bliss with blankets of warm perma-chords/pads, minimal bassline, hypnotic broken beats

This week's #TuneTuesday theme is #lullabies. While not strictly a lullaby, the opening chords of this song would calm Kid1 instantly, even when only days old and even in the midst of the worst tantrum, and keep him enthralled for the duration. It still does more than a decade later. It's one of a very …

Analysis and Visualization of Musical Structure using Networks
In this article, a framework for defining and analysing a family of graphs or networks from symbolic music information is discussed. Such graphs concern different types of elements, such as pitches, chords and rhythms, and the relations among them, and are built from quantitative or categorical data contained in digital music scores. They are helpful in visualizing musical features at once, thus leading to a computational tool for understanding the general structural elements of a music fragmen…

One more. Maybe 1975? Age 18. Mid-50s #Gibson L-55. A friend told me his uncle had an old guitar he wanted to sell. Went over there, played a couple of jazzy chords that I had just learned. The uncle shrugged and said, "How about $75?" sold! Had to sell it in 1994 to pay rent when I was an intern at Duke.

Punk in Africa (documentary) - African Music Forum
Punk in Africa, is a 2012 multilingual African historical punk music documentary against a backdrop of intense political struggle.

A few years ago (December '21), a new forum member showed up on Maker Forums, wanting to brainstorm ideas for what he reasonably thought would be the first ever pedal steel guitar that could be tuned under computer control instead of mechanical linkages from the pedals.
Amazingly, 132 comments later, in April '23 another new forum member showed up, who it turned out had already built such a thing, and provided rich detail.
156 posts into the thread, it is still active t…

#OTD in 1979 The #GiveEmEnoughRope tour played the Ontario Theater in Washington DC. Uk based band #TheClash brought along one of their heroes, USA rock n roll progenitor

#ListeningClub I dig the just throw any idea in thing going on lately. Video game like synth chords, followed by an autotuned opening. 🔥

brb, why aren't there parliament charts but in golang instead of JS
(the JS algorithm for calculating the chords and number of seats on each semicircle is here: https://github.com/juliuste/parliament-svg/blob/main/src/index.js - I suppose making one in golang that makes an SVG is possible? or with some /wild/ CSS3 code transforms)
I like this visualization because it easily grows or shrinks with the size of the parliament in question.

The total chord length of maximal outerplanar graphs

The total chord length of maximal outerplanar graphs
We consider embeddings of maximal outerplanar graphs whose vertices all lie on a cycle $\mathcal{C}$ bounding a face. Each edge of the graph that is not in $\mathcal{C}$, a chord, is assigned a length equal to the length of the shortest path in $\mathcal{C}$ between its endpoints. We define the total chord length of a graph as the sum of lengths of all its chords. For each order $n\ge 5$, we find outerplanar graphs whose total chord length is minimal among all graphs of the same order, and grap…

A great practice day, even got a chance to sneak in some Elvis, which is never a bad thing.

Mustango: Toward Controllable Text-to-Music Generation
The quality of the text-to-music models has reached new heights due to recent advancements in diffusion models. The controllability of various musical aspects, however, has barely been explored. In this paper, we propose Mustango: a music-domain-knowledge-inspired text-to-music system based on diffusion. Mustango aims to control the generated music, not only with general text captions, but with more rich captions that can include specific instructions related to chords, beats, tempo, and key. A…

Musical Systems with $\mathbb{Z}_n$ -- Cayley Graphs
We apply geometric group theory to study and interpret known concepts from Western music. We show that chords, the circle of fifths, scales and certain aspects of the first species of counterpoint are encoded in the Cayley graph of the group $\mathbb{Z}_{12}$, generated by $3$ and $4$. Using $\mathbb{Z}_{12}$ as a model, we extend the above music concepts to a particular class of groups $\mathbb{Z}_{n}$, which displays geometric and algebraic features similar to $\mathbb{Z}_{12}$. We identify a…

Characteristics, Implementation and Applications of Special Perfect Entangler Circuits
We discuss the characteristics of special perfect entanglers and construct single parameter two-qubit circuits which are locally equivalent to special perfect entanglers. We present the results obtained from the implementation of one of the circuits using cross-resonance interaction and discuss their applications. First, we show that the ability of two-qubit gates to create entangled states can be described using the chords present in the argand diagram of squared eigenvalues of nonlocal part o…
