It's sort of amazing that one of the most popular living classical composers - Arvo Pärt, who runs neck and neck with John Williams in how often his music gets played live - uses a mathematical system to create his music. Here's a great video on how it works.

Briefly, he likes to compose with two voices, which he calls the M-voice and the T-voice. The M-voice plays melodies in a diatonic scale, which are often mathematically patterned. The T-voice is restricted to playing notes in a particular triad, following a precise rule. For example, it might play the lowest note in the triad that's above the M-voice.

This produces a unique effect. The restrictions, and Pärt's use of religious texts, give the music a vaguely medieval sound. But it's not really like that old music at all. Since the M-voice stays in a diatonic scale, and T-voice stays in one triad, the music sounds very 'pure'. But the rules sometimes put the T-voice just a tone or semitone away from the M-voice, hence dissonant. The result sounds both ancient and futuristic.

Here I haven't even gotten to the symmetries in Pärt's music! For that, watch the video. You'll be able to see the patterns while hearing them.

When we talk about welfare we usually focus on the vulnerable & the poor... however as Prem Sikka argues here (implicitly following earlier work by Kevin Farnsworth), one of the real major recipients of government welfare is the corporate sector.

[Farnsworth neatly called this 'Corporate Welfare']

The normalisation of this help to corporations, while welfare cuts hit the recipients of what we usually see as 'welfare' is the story of C20th/21st capitalism.

That would be incredible. I wish regulators would make Commons Enforcement a regular part of their playbook.
