Rosin Violin
The effects of rosin type on violin sound?
Yes, this is about science fair. I am in 8th grade and I want to do a SF project on violins, and this is the only idea I can find. How would I numerically and accurately measure how different types of rosin affect the sound of a violin?
Also, same question, but instead of rosin, with bow weight?
And, If you know of any, are there any better violin SF projects that fit into the category of numerically measurable?
Instead of how nice the sound is, I’m going for how loud ….. or some other variable.
If you have access to an oscilloscope that would be the most objective numerical way to measure the difference.
you could just use a contact pickup and plug that into the scope to measure the sound-waves.
If you don’t have access to an oscilloscope scope you can make a crude device that does basically the same thing.
you need a strobe light, and a digital camera that will take lots of pictures in a second. set the camera to the shortest possible exposure (must be less than .1 seconds to work for this) sync the camera and strobe light up, and you will be taking pictures of the variation in the vibration of the violin strings as a result of the different rosins. you then just need to graph the results.
