The Sinfonian.
It began in 1901 as
The Sinfonian Yearbook. Starting in 1909, the
Yearbook was supplemented by a three-times-per-year newsletter called
The Mystic Cat.
In 1915,
The Mystic Cat became the only publication, and in 1917 the name was changed to the more "dignified"
The Sinfonian.
We also have a newsletter for chapters and collegiate members called
The Red & Black.
