by: Understanding Music

QUESTIONS:

1. What is sound? What are the three main properties of sound?

2. What is music? How does it relate to sound?

3. Did you already know anything mentioned in this video? If so, what?

4. What is something new you learned or found interesting in this video?

5. Do you think there is a difference between hearing and listening?

6. How will a deeper understanding of sound help with listening in music class as we move into our next unit on music history and then into music composition?

Sound is an acoustic wave through a medium of gas, liquid, and solids.

Music and noise are both mixtures of sound waves of different frequencies. A sound wave coming out of a musical instrument, loudspeaker, or someone's mouth pushes the air forward and backward as the sound propagates outward. This has the effect of squeezing and pulling on the air, changing its pressure only slightly.

you have to answer 3, 4, 5, and 6 on your own. Those are personal questions.

Explanation:

perimeter = 2l +2w, divide total perimeter by 2 for total length of 1 side and 1 width

172/2 = 86 (  total for 1 side and 1 width)

86-24 = 62 (since length is 24 ft longer subtract 24 then divide by 2 for width)

62/2 = 31

width = 31 feet

length = 31 +24 = 55 feet

check: 31*2 = 62, 55*2 = 110,  110+62 = 172

hey

he was  an italian composer who wrote 39 operas, as well as some sacred music, songs, chamber music and piano pieces.
