Undoubtedly the best language for the expression of this ‘unfathomable' quality was music. The infinity of musical spheres of expression, independent of rationality, is often perceived as ‘unfathomable' by listeners too. The formal principles of order seem to lie hidden deeper in this art than in others. In the twentieth century the great creative minds, when faced with Romantic artistic urges running riot which they believe must be overcome, or feel they have succeeded in overcoming, have stressed the importance of existing rules; they have followed traditional forms, or else, in their search for new ways to connect, have found and set up new formula-tions and principles. The young Schumann's creative path led in the opposite direction, from classical forms, however deeply revered, to the freedom of subjective self-expression.
