Our five senses of perception - hearing, touch, sight, taste, and smell - are only indirectly involved in the process of gaining knowledge. They convey to the intellect, to our organ of cognition, the playful expression of that which has been mentally created, and thus complement the monologue of our self-awareness to the full cycle of a thought which is created out of the self-awareness, and which again merges back into the self-awareness.

The thought is offered to the delighted senses by the mind, and is only the concrete image of an inner, abstract form, of an idea in the world of our self-awareness. And from the level of his self-awareness, the musician comprehends the synthesis of content and form and expresses this unity in his music - the unity of the musical creator with the music created and with the process of creating music.

As explained earlier it is the musical poet in particular who condenses content and form in such a way that these two components do not fall apart so that the music will reach both the feeling and the understanding of the listener in an integrated manner.
At the same time, we have explained, his musical instrument is to the musician at best a means for the outer presentation of what he originally must hear within.
And moreover we have stated that speech basically is also the domain of music - which means that essentially there is no difference between speech and music.
