Professors were hired for their knowledge of a subject, not because they were of the proper faith and had a strong arm for disciplining students. 被聘請的教授不再是因為他們有恰當的理念和會管教學生的有效方法，而是由於他們具備某一學科知識上的造詣。
Viewed from the professional and non-substitutive angle, the most essential competencies are knowledge and skills in both education and music. 從不可替代的專業立足點來看，教育理論及實踐能力和音樂學科知識及能力二者學術水平的同步提高是確立音樂教師專業化水平最為重要的方面。
