Bore Shapes
The cone and the cylinder are the two idealized shapes used to describe the bores of wind instruments. These shapes affect the harmonics associated with the timbre of the instrument. The conical bore has a timbre composed of odd and even harmonics, while the closed cylindrical bore or closed tube is composed primarily of odd harmonics. The harmonic characteristics of instruments such as the clarinet (closed cylinder) are more variable than a given waveform and bore alone is not the only determining factor. The timbre of a clarinet, for instance, depending in the main on the construction of the mouthpiece which is neither a cone nor a cylinder and the properties of the reed. Furthermore, minute changes in air pressure and pressure applied to the reed modulate (vibrato, slurs) the tone.

Famous quotes containing the words bore and/or shapes:
“Poetry is either something that lives like fire inside you—like music to the musician or Marxism to the Communist—or else it is nothing, an empty formalized bore around which pedants can endlessly drone their notes and explanations.”
—F. Scott Fitzgerald (1896–1940)
“Painting dissolves the forms at its command, or tends to; it melts them into color. Drawing, on the other hand, goes about resolving forms, giving edge and essence to things. To see shapes clearly, one outlines them—whether on paper or in the mind. Therefore, Michelangelo, a profoundly cultivated man, called drawing the basis of all knowledge whatsoever.”
—Alexander Eliot (b. 1919)
