Document Summary
The range of sound that humans can hear extends from around 20 to 20,000 cycles per second. Noises with unfocused vibrations do not have pitch. Amplitude- the level of strength of sound vibrations. Dynamics- the level of sound: forte- loud, piano- soft. Tone color/timbre- the qualitative difference between how two instruments sound: to create timbre, the strings on a piano or stringed instrument can vibrate in halves or even eighths. *the amount and exact mixture of overtones are what gives an instrument its timbre* Instrument timbres: strings sound produced from vibration created between string and sound box. Different sized instruments= different tones: woodwinds vibrations of air in different columns. Different shapes and different ways air is moved= different pitches: brass player"s lips vibrate against the cup of the mouthpiece. Different mouthpieces/tubing size= different register of tone: percussion produces sound by being struck or shaken. Unpitched percussion instruments are without a fixed pitched (ie tambourine)
