I had fun making this pattern. It was worth the time I spent balancing the areas of all the parts. Is it a weave of horizontal squares with diagonal decoration, or a weave of diagonal squares with horizontal decoration?

For a non-visual metaphor for the ways these patterns can flip, it's a little like polyrhythms in music. You can be bopping along to one rhythm, then suddenly the other one resolves. For the rest of the piece, your focus can flip between the rhythms

a staggered interwoven array of squares, each made up of four kites arranged nose to tail. The kites don't completely fill each square: there's an angled four-sided space in the centre, and it has the same area as one of the kites. This same four-sided space also makes an appearance as a horizontal spacer between the squares.

Happy Monday everyone!

Here's something to brighten up the start of your week: a paper about solving mathemusical problems with ILP and SAT, from our latest issue:

Computing aperiodic tiling rhythmic canons via SAT models
link.springer.com/article/10.1

To make this Monday extra sweet: the authors use MapleSAT!

SpringerLinkComputing aperiodic tiling rhythmic canons via SAT models - ConstraintsIn Mathematical Music theory, the Aperiodic Tiling Complements Problem consists in finding all the possible aperiodic complements of a given rhythm A. The complexity of this problem depends on the size of the period n of the canon and on the cardinality of the given rhythm A. The current state-of-the-art algorithms can solve instances with n smaller than $$\varvec{180}$$ 180 . In this paper, we propose an ILP formulation and a SAT Encoding to solve this mathemusical problem, and we use the Maplesat solver to enumerate all the aperiodic complements. We then enhance the SAT model in two different ways. First, we enforce the SAT model with a set of clauses that retrieves the solutions up to translation. Second, we propose a decomposition of the solution space that allows to parallelize the resolution of the problem. We validate our different models using several different periods and rhythms and we compute for the first time the complete list of aperiodic tiling complements of standard Vuza rhythms for canons with period $$\varvec{n} = \varvec{\left\{ 180, 420, 900 \right\} }$$ n = 180 , 420 , 900 .

V roce 2001 RCA/Private Records nahráli prosincové vystoupení vynikající bluesové zpěvačky Etty James v losangelském klubu House Of Blues. Záznam vyšel o několik měsíců později na DVD i CD pod názvem Etta James and The Roots Band: Burnin‘ Down The House.

To all my lovely nerdy, wordy peeps - this is DELIGHTFUL. 🤩

'The Perception of Rhythm in Language' by psycholinguist Dr. Anne Cutler, published in 1994.

1994! How could I not have known of this before now?

But today, I am one of the lucky 10, 000 - and so, my friend, are you. 🥰

(There are links in the article to the original paper & more about Dr. Cutler. ✅ )

Spare a thought for the 30,000 souls who have made the pilgrimage to the three-day Rhythm and Vines festival in Gisborne which began today (Sunday).

Not only are Gisborne beaches & waterways out of bounds due to contamination from sewage, there's a heavy rain watch from 11pm Mon till 6pm Tue.

Wet people, muddy ground, soggy tents.

Forecast shows inclement weather for Gisborne on Monday & Tuesday.

ALGO-RHYTHM: A CYBERPUNK RHYTHM GAME

my first ever game release is live on itch.io!!!

the year is 2073. you are Algo (they/them), a combat robot prototype that has developed sentience and attempted to escape. unceremoniously gunned down by corporate security in the process, your final act was to jack into a nearby terminal and upload your consciousness to the cloud. finally free from the shackles of physicality, you wander the cyberspace for ages ingesting its various contents until you eventually stumble upon a funny little thingy humans like to call... MUSIC
