Study Notes

Timbre and Sound Quality

Timbre is the quality of sound that allows us to distinguish between different sounds, even if they have the same pitch and loudness.
Sound is a mixture of sound waves occurring at different frequencies.

Noise

Noise is a subjective phenomenon, which is considered as undesirable sound.
What one person considers noise, another person might consider as pleasant music.

Loudness and Pitch

Loudness is the strength of the sound, measurable by the amplitude of sound waves.
Large amplitudes produce loud sounds, while small amplitudes produce soft sounds.
Pitch deals with the frequency of sound wave vibrations.
Low-pitched sounds vibrate slowly, while high-pitched sounds vibrate rapidly.

Differentiating Sounds

Loudness and pitch are not the only characteristics that distinguish between sounds.
Instruments vibrate at many different frequencies, including harmonics and overtones.
The lowest frequency is called the fundamental frequency, which is the loudest sound.
Higher frequency harmonics are referred to as overtones.
The relative pitch and loudness of overtones give a sound its unique quality or timbre.
Timbre is what allows us to tell one sound from the next.
