They probably think because I am so small and young, nothing of greatness and class can come out of me; but they shall soon find out. - Wolfgang Amadeus Mozart

When I am, as it were, completely myself, entirely alone, and of good cheer — -say traveling in a carriage, or walking after a good meal, or during the night when I cannot sleep — -it is on such occasions that my ideas flow best, and most abundantly.

The human voice vibrates naturally - but in such a way - to such a degree that it all sounds beautiful - it is the nature of the voice. We imitate such effects not only on wind instruments, but also with violins - even on clavier - but as soon as you go beyond the natural limits, it no longer sounds beautiful - because it is contrary to nature.
