Types of Musical Instruments Musical Instruments are classified by the way they create tones of sound. Each type of musical instrument creates tones in different ways. The most common methods for producing tones are:
Stringed Musical InstrumentsIn stringed instruments, the sound source is a tensioned, vibrating string. The length, thickness, tension and density of the string all affect the pitch of a given string. Longer, thicker, and looser strings vibrate slower than shorter, thinner, tighter strings. After tuning a stringed instrument, the player can fret (press down) on the strings at certain points to shorten the vibrating portion of the string, thereby changing the tone that is produced.

Wind Musical InstrumentsIn wind instruments, the sound source is a vibrating column of air inside a tube. The length and diameter of the vibrating air in the tube affects the pitch. The more volume of air vibrating, the lower the pitch. A wind instrument player can adjust the areas of vibrating air by opening and closing holes along the instruments length.

Drum and Percussion InstrumentsIn percussion instruments, the sound source is a vibrating membrane (like a drum head), or a vibrating piece of material (like a xylaphone). The drummer / percussionist causes the material to vibrate by hitting, striking, shaking, or rubbing the instrument.

Musical Instruments and the Science of Sound Musical tones are longitudinal vibrations of air, at specific frequencies / wavelengths. Each musical note corresponds to a specific frequency / wavelength. For instance, the standard tuned 'A' note has a frequency of 440 hertz (440hz), which means that the wavelength passes through the air at 440 cycles in one second. The corresponding wavelength of the note 'A' is about .75 meters.
