"[The untutored man] is able, without an effort, to listen objectively to what he hears and judge it for what it is worth; whilst the professionally trained musician is subconsciously collating his impressions with the technique which, as it was imparted to him in musical infancy, has become sacrosanct. In other words, he has a difficulty in hearing music as it sounds, without at the same time hearing how it ought to sound according to his conception of music."
Newman in M.D. Calvocoressi (1923) “The Principles and Methods of Musical Criticism” Oxford University press, London. p. 83
