Violin strings are thin and tight. When people play it, the strings vibrate and make sound. The strings vibrate so quickly that people could not actually see its vibration. So how do strings actually move? Well, check this out. https://www.youtube.com/watch?v=6JeyiM0YNo4&index=4&list=PLE35BD0AB93E47FB6
Why Blowing in Bottles Makes Sound and Helmholtz Resonance
Here is an informatitive video i found online explaining Helmholtz Resonators. It really helps further understand the information shown in class today. It also touches on a few concepts that we already learned about before such as simple harmonic oscillators. Seeing this differently than in class makes it all a little easier to grasp with the diagrams shown and pictures. I hope it helps others as well.
Good video; thanks, Robert!
I was just searching youtube for interesting videos that had to deal with stuff we were learning about in class. I found a lot of interesting stuff but when i saw the title of this video i knew i had to watch it. It was called “freezing water with sound”. Before I watched this video i thought that this wasn’t physically possible. After watching the video i found out that when water is put through a tube over a particular frequency it makes the water appear to look frozen or at another frequency it makes the water look like it is traveling backwards. This video has nothing really to do with anything that we are learning in class besides it talks about frequency but I found it to be extremely interesting and something that people could enjoy.
I came across this video and I thought it was really cool. A video was posted that on here was made by the guy about sine waves. It uses water to show sin waves, but this is another experiment that actually shows the reverse of the sin wave. https://www.youtube.com/watch?v=uENITui5_jU
Music has such a large impact on our daily lives and we don’t even know it. I find it interesting that children who were taught how to play a musical instrument and had regular interaction with these instruments are more likely to have a higher verbal IQ and visual abilities. Also, have you ever felt chills go down your back when listening to music? Apparently, the stronger the chills you feel, the higher you are in one of the five personality traits. Music is also known to reduce blood pressure and heart rate. Another health benefit of music is the effect it has on stroke victims. 60% of people who have a stroke become visually impaired, however, studies have found that when patients listen to their favorite music, some of their vision is restored. It’s cool to think about music in a way other than just sound that comes through a speaker. Any experiences or thoughts about this? I’d love to hear them!

Kelsey, great find! Its amazing to see the benefits of playing a musical instrument can have on a person. A trumpet player myself, I can relate. Throughout my high school career my music instructor always said the brightest students our in band. Looking back, he was right! My high school top 10 percent was made up of the senior high concert band. It was interesting to read that music can reduce blood pressure and heart rate. I found that the hypothalamus is a part of the brain that helps regulate our breathing, heartbeat and other automatic body responses. It’s also linked to emotional activity. So how does music help? When you listen to music that makes you think of happy memories, it affects the hypothalamus in a way that helps slow your heart and respiration rates, as well as lower your blood pressure. Recently, I had found that music can help with memory loss too! For many people suffering from memory loss the spoken language has become meaningless. Music can help patients remember tunes or songs and get in touch with their history. This is because the part of the brain which processes music is located next to memory. Overall look at all the benefits either playing or listening to music can do for you.
Hey Kelsey this is an awesome blog. I was always curious about how we are literally able to feel music. Your link reminds me of another link I read about how fetuses respond to music while in their mother’s womb. The process is called Prenatal Music Stimulation. Parents often use music to communicate with their unborn child. Ultimately, it is suppose to encourage mental, physical, and sensory development. This is basically what your summary describes except for with adults. It is truly amazing how music touches us mind body and soul even before we are born. Here is the link that goes into further detail about the benefits of Prenatal Music Stimulation:

We did talk in class about instruments being played underwater. When I came across this video I wasn’t sure if it was real and I’m still searching for an answer because the music sounds so clear. When we are underwater we can hear sound but not as clearly as we do in air. For example when you go underwater and try to talk to the person next to you sometimes you can understand them, other times you hear the sound but are unable to make a connection as to what they’re saying. I would love for someone to give some input as to how this video was made.
Actually, the pitch shouldn’t change depending on where you’re listening from. If the instrument is creating 440 vibrations every second, there are 440 vibrations every second traveling through the water and 440 vibrations every second “escaping” into the air. The wavelengths in the air and the water will be different because of the different sound speeds, but our ears interpret frequencies, not wavelengths.
I am surprised that you can actually get a sound out of a violin underwater (never mind the fact that you’d ruin the instrument by submerging it!). As we’ll see in class on Thursday, the air cavity inside contributes a lot to the sound, and filling it with water certainly changes that contribution. Also, the fact that water is a lot heavier than air should mean that it’s much harder for the wood to vibrate and amplify the sound. Finally, the friction between the bow and the string would certainly be affected if everything was wet, probably making it harder to produce a sound.
Interesting idea, though!
Miranda, I thought this video was extremely interesting. I’ve never actually seen anyone play underwater before. I had some doubts as to whether or not this video was real as well. I would assume it was real, since we know that sound can travel through other media besides air (i.e. water). I did a little bit of research. I found that the sound heard in this video is only the sound that has escaped the surface of the water. If the video was taken underwater in the same tank as the musician, we would hear the pitch and frequency differently as we do out of the water. According to a blog I found, hydrophones were not used in this video, meaning we only hear the sound of the violin that passed through the surface of the water. “The pitch as heard in the video was the same as the sound of it underwater which pretty much proves it was sound recorded above the surface where you would hear normal air frequencies, the pitch should change a lot because of the increased speed of sound underwater” (Redhotpawn). The viscosity of the water vs. air would most likely change the frequency (pitch) and amplitude (loudness) of the sound waves we hear as well. I thought the sound of the violin played underwater produced a very eerie sound. He must have a lot of skill to be able to play underwater, holding his breath and not seeing clearly!

Did you know that listening to music at certain times of the day can actually improve your day as a whole? This article I found talks about different types of music and how it can affect your mental state of being. By listening to certain types of songs at certain times of the day, productivity, attitude, and many other factors of your mind can and will be affected. The article even gives several example songs from each category and time to listen to it. Give it a try! http://mic.com/articles/99508/science-shows-what-music-to-listen-to-at-every-moment-of-the-day
I thought this was really interesting because I agree that music affects or helps aid certain moods. Taking the example of letting out negative feelings by listening to sad music is definitely true. After having a really bad day or being upset over a situation sometimes just wallowing with some sad music is just the trick to get it out of your system. But on the flip side listening to certain music when you’re in a negative mood connects those certain emotions you feel whenever you hear that certain song. Personally, if I hear a song that I listen to only when I’m in this specific mood it always brings me right back to that psychological state and I can’t stand it!
As for the upbeat music helping out with a workout, this is extremely true!!!! One of the trainers at my gym use to be a track coach. He said that he wouldn’t allow his team to listening to any music while running because they got so use to relying on music as a motivator to run. I can’t imagine ever exercising without music, I wouldn’t be able to go that extra limit!
It’s crazy how music really does enhance your feelings, I like this article because I think everyone can link at least one of these examples. Except the male teen drivers listening to “Norah Jones” to prevent reckless driving. I don’t think we will catch that anytime soon, haha!
Good post.
Did you know that music is not only a luxury, but actually a necessity? I found an article from TCNJ Journal that discusses the effects of music on our brain and emotions. It states that music is actually exercise for our brain. When we listen to music, we are unconsciously dissecting the songs and trying to follow the beats, recognize the different octaves, and identify the notes of the instruments and voices. Music forces to use multiples levels of thinking simultaneously without us even realizing it! Check out the article below! http://tcnjjournal.pages.tcnj.edu/2013/04/13/the-science-behind-music/
Remember Professor Falco once took out two black plastic strip, and played them by striping with her nail? The first one said “Happy Birthday”, and the second one said “College is a good place” or something alike. That is exactly how old gramophone record works! And it is the base of analog signal which used by magnetic tape and CD music! This video shows us how a gramophone record was made, and you can just think it as the way they made magnetic tape music, which was once very close to people’s liveshttp://www.youtube.com/watch?v=yrq4fwKjaIs
I was doing some research, and I found this cool website that talks about brain frequencies and how music and sound can effect them. For example one of the brain frequencies that has been given the name “Alpha” is when our brain is relaxed and focused. People can train their brain to operate in this frequency by using a process called “brain entertainment.” During “brain entertainment” you can train your brain to change brain frequencies by listening to certain sounds and tones.
