Simple Harmonic Motion • Vibration about an equilibrium position in which a restoring force is proportional to the displacement from equilibrium. • Harmonics is a the idea of simple harmonic motion applied to more complex situations involving sound.
Standing Wave • A wave pattern that results when two waves of the same frequency, wavelength, and amplitude travel in opposite directions and interfere. • What is a stringed instrument? • A fixed boundary with two nodes.
Understanding Waves in Strings • Fundamental Frequency-The lowest frequency of vibration of a standing wave. • Harmonic Series-a series of frequencies that includes the fundamental frequency and integral multiples of the fundamental frequency. • Relates wavelength on a stringed instrument to pitch.
Waves in an Air Column • Examples of sound waves in an air column…. • Organ, Flute, Clarinet • Two types Harmonic Series with an open pipe and a closed pipe. • Examples of a closed pipe. • Examples of an open pipe.
Harmonics • Accounts for sound quality or timbre. • Fundamental frequency determines pitch.
