Mozart's mental grip never loosens he never abandons himself to any one sense even at his most ecstatic moments his mind is vigorous, alert, and on the wing. He dives unerringly on to his finest ideas like a bird of prey, and once an idea is seized he soars off again with an undiminished power.

Mozart 's music is very mysterious.
