476/475, the hedwigma, is a 19-limit superparticular comma of about 3.64 cents. It is the amount by which a stack consisting of two 5/4s and one 19/17 falls short of 7/4. By tempering it out is defined the hedwigmic temperament, which enables the hedwigmic chords.
Etymology
The name hedwigma was named by Xenllium in 2023. It refers to 476 Hedwig, the asteroid. Which in turn was named for the wife of Swedish–Danish astronomer Elis Strömgren.
