Abstract
The important two kinds of theory on the essence of music in the history of music aesthetics : 1) Music as an art of expression, 2) of non-expression. (The former is subdivisible into two-immanent and transcendent) The result of consideration : All sorts of music actually have both sides, expressive and non-expressive, constructive or absolute. The most important conception to be found in the very essence of music. Music itself to be found in sounding tone-work, which might have fore- and back-grounds in which the dynamic aspects of all human or universal beings and relations can be projected. In conclusion : Music or art of tone can be assuredly defined as an art of absolutness in the meaning of autonomy, although sometimes it might decline to the expressive (heteronomic) side.
