Note 35 — Chapter VI · THE PHILOSOPHERS, AND GREEK SOCIAL MUSIC.

The sense of sound differs in different ears. In Chappell’s Histy. of Music, page 251, an account is given of a wire of sixty-four feet in length, arranged by Sir F. A. Gore Ouseley, to sound the C, four octaves below C in the bass clef. The note was inaudible, but when taken at half length some of the listeners heard it, while at quarter length it was audible to all.
