Music: An Art and a Language
“ CHAPTER IV THE MUSICAL SENTENCE BEFORE passing on to an explanation of the fundamental types of musical structure, we must give some idea of the constituent parts of the Period in music. Every art has its units of expression: the straight line, the curve, the arch, the poetic stanza and the prose sentence. Just as poetry and prose are a series of stanzas or sentences, so a musical composition is a succession of definitely organized portions of thought and emotion, in terms of rhythm and sound. ”
