MMM – Memos on Math/Music: This site lists memos on music and math by the site owner.

The music will be listed as mp3 files. Those files have a portrait of the composer as an eye-catcher:

e.g., J. S. Bach’s music on periodic instrumentation has the following portrait,

whereas modern interpretation of J.S. Bach’s music has the following portrait.

Many thanks from the site owner to MuseScore https://musescore.com/ without which he can never create mp3 files.

The math will be listed as PDF files. Some of them are typed using conventional word processors, and others are in LaTeX. Those files have “Girl with a Pearl Earring” by Johannes Vermeer as an eye-catcher: see below.

The site owner would like to express his appreciation to his cousin and the spouse (of the cousin) for suggesting that he should set up a site to list his “achievement” so far.
