Possessive "its" should have an apostrophe and 100 - 200 CE should be called the "first century"

A melody in which the ratios of the number of vibrations in each pitch are the same as the ratios of the number of letters in each word of this sentence.

I love the fermata. Kind of a "some of us are better at this than others" indicator.

There's not a reason supplied in the text. Maybe he had a strong feeling about the tempo of adagio and felt he could sustain one bow for 12 beats and then a bit more? Or perhaps it comes from an example in the repertoire? It's a good puzzle though!

The oldest single-note piece I've found so far (1834). From "L'art du violon" by Pierre Baillot.

Today's violin meditation: a 1008-second tone that bends up one whole step and then back down, in such a way that it forms the top of a 100-pitch 1-hour circle on a pitch/time grid.

A tone (147 1421/3600 Hz, when A=442 Hz), tunable by ear on the viola, which, when sustained, has a unique phase during each second of an hour

I'm working on a catalogue of written-out parts for change ringing on handbells, designed for people who want to enjoy
the musical richness of change ringing without the obstacle
of having to memorize each pattern. I'll keep adding more here:

I love diagrams that portray musical intervals as semicircular arcs. I'm starting a little catalogue of them here: midnightsledding.net/arcs/arcs.html
Let me know if you have any tips on other examples?

A surprising number of pages from the handwritten manuscript of "Tristan and Isolde" use every staff on the page. Gonna write a paper about how the orchestration was determined in large part by Wagner's choice of music paper.

When I took my current job, I had to sign a paper saying that I would defend the Constitution of the United States, and I feel like maybe there should have been some online training assigned to me on this topic.

To celebrate the new year, I'll do two performances one hour apart. One at 11pm on December 31 and one at midnight on January 1.
Both will consist of a tone sustained for 1/8760 of the remaining duration of the year.

I'm resuming the podcast that I started in 2016: once and a while my computer randomly records one second of audio from a microphone in my living room and then posts it as this podcast.

I've been exploring what I'm calling "Complete-Harmony Canons", which are canons that result in all possible harmonies (once and only once, ignoring pitch doublings) depending on the number of voices and the number of pitches that are used. (examples in the link)

I feel its lack of usefulness would be a feature not a bug
