THE MATERIALS OF MUSIC:
SOUND AND TIME
![Page 2: THE MATERIALS OF MUSIC: SOUND AND TIME. WHAT IS SOUND? The sensation perceived by the organ of hearing (ear) when vibrations (sound waves) reach the ear.](https://reader035.fdocuments.us/reader035/viewer/2022062306/5a4d1b417f8b9ab0599a12ab/html5/thumbnails/2.jpg)
WHAT IS SOUND?
• The sensation perceived by the organ of hearing (ear) when vibrations (sound waves) reach the ear

VIBRATION
• Periodic motion of a substance • Instruments: strings, sounding boards, etc. AND the air inside and
around the instrument vibrate

COMPRESSION AND RAREFACTION
-Happens when you activate the sound source

FREQUENCY
• Refers to the number of compression-rarefaction cycles that occur per second• Human range: 20 to 20,000 cycles per second

FOUR PROPERTIES OF SOUND
• Pitch – how high or low a sound is• Intensity – how loud or soft a sound is• Duration – how long or short a sound is• Timbre – quality or color of a sound

PITCH
• The greater the number of sound waves, the higher the pitch• TONE – a musical sound of definite pitch

INTENSITY (DYMANICS)
![Page 9: THE MATERIALS OF MUSIC: SOUND AND TIME. WHAT IS SOUND? The sensation perceived by the organ of hearing (ear) when vibrations (sound waves) reach the ear.](https://reader035.fdocuments.us/reader035/viewer/2022062306/5a4d1b417f8b9ab0599a12ab/html5/thumbnails/9.jpg)
DURATION (METER AND RHYTHM)
• METER = Regularly recurring pulses of equal duration (STEADY BEAT) FORMS MEASURES
• DUPLE = Two-beat
• TRIPLE = Three-beat
• RHYTHM = Patterns of uneven durations Can be almost any length

TIMBRE
• Permits us to distinguish between a clarinet and an oboe, for instance
