Wind instrument a half-wavelength. To a rough approximation, a tube of about 40 cm. will exhibit resonances near the following points: In practice, however, obtaining a range of musically useful tones from a wind instrument depends to a great extent on careful instrument design, and playing technique. The frequency of the vibrational modes depends on the speed of sound in air, which varies with air density. A change in temperature, and only to a much smaller degree also a change in humidity, influences the air density and thus the speed of sound, and therefore affects the tuning of wind instruments. The effect
