What is Amplitude?

  • The scientific measure of loudness What is a cent?

1/100th^ of a step. What is compression?

  • Region of air where molecules are pressed together What is CPS?
  • Stands for cycles per second. This is a measurement of frequency (measures the number of times something vibrates) Equal Temperament - tuning system where an octave is divided into 12 equal ½ step intervals.  We use this because it makes playing in multiple keys and playing modulations significantly easier. What is the fundamental?
  • First note of the overtone series. This provides the perceived pitch. What is a harmonic?
  • Any note in the overtone series What is an overtone?
  • Any partial other than the fundamental What is a phon?
  • This is the measure of perceived loudness What is rarefaction?
  • The opposite of compression. Particles move away from each other What is a sine wave?
  • Pure sound. Contains no overtones. Has only one partial, which is the fundamental. What is spectrum?
  • Shows strength of particles. This is the scientific term for timbre What is timbre?
  • Tone color of voice/instrument. This distinguishes sounds from other sounds
