  1. The materials of music: Sound and time

  2. What is sound? • The sensation perceived by the organ of hearing (ear) when vibrations (sound waves) reach the ear

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

  4. Compression and rarefaction -Happens when you activate the sound source

  5. Frequency • Refers to the number of compression-rarefaction cycles that occur per second • Human range: 20 to 20,000 cycles per second Video https://www.youtube.com/watch?v=zKwpv8mZHRM

  6. 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

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

  8. Intensity (dymanics)

  9. 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

  10. TIMBRE • Permits us to distinguish between a clarinet and an oboe, for instance • http://www.musictechteacher.com/music_quizzes/aq_identify_the_instrument_sounds/quiz.html
