All sound starts with something that vibrates. The reed in a clarinet vibrates, the vocal cords in a singer's throat vibrate, the air flowing over the mouthpiece of a flute oscillates, and the speaker cone on your stereo or in an ear-bud vibrates. In this chapter we investigate a particular kind of vibration called simple harmonic motion. Most of the vibrations in musical instruments and the human voice can be described approximately by simple harmonic motion.

Key Terms:

Periodic, period (cycle), linear restoring force (Hooke's law), non-linear restoring force, amplitude, displacement, phase, frequency, natural frequency, spring constant, simple harmonic motion, damped harmonic motion, damped driven harmonic motion.
