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.
