1. Properties of Sound

2. Four Properties of Sound
Frequency (pitch)
Amplitude (volume)
Timbre (quality/color)
Duration (length)

3. 1 Hertz = 1 vibration/second
Frequency
A sound wave is created by vibrations.
The vibrating object which creates the disturbance could be the vocal cords of a person, the vibrating string and sound board of a guitar or violin, or the vibrating diaphragm of a radio speaker.
1 Hertz = 1 vibration/second

4. A normal human can hear between 20 Hz and 20,000 Hz
Examples of different Frequencies…
Test your hearing….Where do you cut off?

5. Frequency Examples 16.35 Hz: Lowest note for tuba, large pipe organs
32.70 Hz: Lowest C on a standard 88-key piano
65.41 Hz: Lowest note on a cello
Hz: Lowest note for viola
261.63: “Middle” C

6. 523.25: Lowest piccolo note
: Highest note in female human voice
2093: Highest note for a flute
4186: Highest note on a piano
16744: Tone a non-HDTV emits while running

7. Pitch Definition: The highness or lowness of a sound
The higher the frequency, the higher the pitch
The lower the frequency, the lower the pitch

9. Amplitude
The volume level of sound
Measures the height of the sound waves
Measured in decibles (dB)

12. Timbre
(“Tamber”)
The type of sound created

13. Duration
The length of time that a sound is sustained
Rhythm and Meter
Tempo: the speed of the music
BPM: Beats per minute- measures the speed of music

14. Notating Music What is a Staff? Musical Alphabet:
5 Horizontal lines that music is written on
Musical Alphabet:
A,B,C,D,E,F,G
We use a clef to determine where the notes fall on the staff.
