The 19th Sky of Semaphore

Saturday, April 8th, 2017


The 19th Sky of Semaphore is a composition for an imaginary chamber ensemble of two semaphore 19 tuned pianos. Photo by Chris Vaisvil
For comparison I present the same piece in 19 edo. If you listen closely you can hear slight beating in the opening 5th of the piece in the 19 edo version but is not present in the sempahore19 version.
