MUSIC AND SCIENCE. 
187 
paragraphs are built up. This analogy was the basis for the 
title of various old books, "Grammar of Music” ; and it sug- 
gests that there are various independent scales, so that a 
musician versed in one musical language is not likely to 
judge intelligently of another without special training. Also 
it should be remembered that the knowledge of the scales is 
only a stepping-stone to the knowledge and the life of a 
people. 
In a letter telling of an enjoyable visit from the young 
Felix Mendelssohn, Goethe exclaims, "Who can understand 
any phenomenon if he is not thoroughly imbued with the 
course of its development?” This course for our subject will 
become clearer as with the perfected field phonograph the 
study of non-harmonic music enters on a new stage, and re- 
sults accumulate from the many workers now busy in all 
parts of the world. So one looks forward to the time when 
ethnologist and musician, historian, psychologist and physi- 
cist, all believing in evolution, shall cooperate in finding and 
telling the truth about the world’s music ; such truth will not 
only advance our science, but will widen men’s sympathies 
and set them free from some errors, and so contribute to a 
liberal culture.
