Not the rich viol, trump, cymbal, nor horn.
Guitar, nor cittern, nor the pining flute.
Are half so sweet as tender human words. [ Barry Cornwall ]

But the soul is not the body and the breath is not the flute;
Both together make the music, either marred and all is mute. [ Robert Browning ]

To blow is not to play the flute; you must move the fingers as well. [ Johann Wolfgang von Goethe ]

A flute lay side by side with Frederick the Great's baton of command. [ Jean Paul ]

To blow on the flute is not to play on it; you must move the fingers as well. [ Johann Wolfgang von Goethe ]
