Sound

Vibration of sound- waves

Different waves are different lengths

Sound is made of waves that our ears perceive

Speed of Sound

The speed of sound is different depending on the type of fluid that is being observed. It is based off of how fast a disturbance can travel through a fluid due to the relationship between pressure and density. Refer to equation 1.

Speed of Sound Equation(1)

c = Speed of Sound

dP = Pressure Differential

dρ = Density Differential

 

Since there is a relationship between pressure and density a pressure wave builds up has an object approaches the speed of sound. Because of this pressure wave, it is impossible for an object to travel exactly at the speed of sound. The reason why is because as the object flies at the speed of sound the pressure wave will continue to build until it destroys the object. This is why jets have after burners. The after burners are used to get the jet past this building pressure wave and essentially break the sound barrier causing the plane to out run its pressure wave which is referred to as the sonic boom. To relate an objects speed to the speed of sound, the Mach number would be used, which is a unit less number. Refer to equation 2.

Mach Number Equation(2)

v = Velocity

 

Finally, the ideal gas law can also be used to calculate the speed of sound. It will be assumed that an isentropic process will occur. Refer to equation 3.

Speed of Sound and ideal gas law Equation(3)

R = Ideal Gas Constant

Lets talk about the ear

Outer ear- What you see of your ear. Ear Canal has little hair on the inside. When you damage your hearing you break the these little hairs and they don’t grow back.

Sound is measured in Decibels (Db)

At what decibel do you start to lose you hearing? With extended exposure, 85 decibels of sound will cause loss of hearing. Extended exposure is about 10 minutes

Normal conversation is at about 59-65 decibels

Oboe

The Oboe is about the same size as the flute, but it is black. It has about the same number of keys as well.

It is a double reed instrument, which means that both the top and bottom lip play on the reed.

The larger cousin to the oboe is called the English Horn

The tuba is the largest instrument in the brass family but shares the same color traits.

It also plays in the bass clef.

Mnozil Brass- Tuba Solo

Marimba

Keys made of rosewood and is played in both treble and bass clef. Most come in 3 octaves, while some can come in 4 octaves. Uses mallets to strike the keys which makes the sound.

Marimba

Marching Snare, Bass Drum, and Tenor Drum

Uses two sticks on a drum head. Two drum heads and snares use a snare on the bottom.

Maracas

These percussion instruments are hand instruments and have beads or seeds on the inside.

ArkMEA

I had the opportunity to go to a music conference and was exposed to so many great education strategies and had a great time while I was there.

It didn’t matter what instrument you played or part you sang, being a music educator was the importance of this conference. One great thing about the conference was being able to hear Victor Wooten talk about music. The first session I was at he talked about music and how the bass has influenced music. Although I do play the flute, everything he talked about and was explaining was so cool and was something I could relate to. It was so cool how he would ask a question about a song or a musician and people would know what he was alluding to. And when we didn’t know what it was all he had to do was play a couple of notes and the light bulb went on. He also talked about overtones on a bass and when that was first tried. Although some of these aspects don’t relate to me personally, I paid attention to how he was talking and reacting to people. Everyone was paying attention to him and learning in some way. There were also volunteers who went up and sang and also had a good time.

The next session I attended was Salsa for kids. This was so much fun. We got to met Freddie the frog and learn about the newest book he was in. This book obviously had a Latin twist to it. There were lots of different percussion instruments that were used with different rhythms that went with a salsa step. It was also very interactive and would be great for any music class really. Some parts could be taken out for K-3 to make it easier for them.

I got to play with drums next which was my favorite. We learned raps about respect and responsibility. They were created by Dancing Drums for inner city kids which taught them about these things. They also learned about being healthy and keeping there body healthy. I got to play small wood blocks, a djembe,  and an assortment of percussion instruments.

I am learning more and more that there is definitely more then one way to teach music. I have learned some great interactive ways to do it. Whether it be how to engage my class and how to keep there attention; or how to incorporate dancing, playing a percussion instrument and remembering my rhythm; or helping teach students to respect there body and others through awesome percussion rhythms and raps! I very much enjoyed my time at the convention and can’t wait to go again!
