With the xylophone seeming like an implausibility, I figured I could also use my ukulele and guitar to help show what I'm talkinh about

I finally have had a successful batch of sugar glass, unfortunately, I lack the resources to make more than a few block, still I can use them to blocks of different sizes to show how the size of a substance affects the sound it makes.

I decided to make a sample of sugarglass in order to find the speed of sound in it, which will in turn allow me to find the correct lengths of sugarglass I will need to cast. I made a simple wooden mold on 1"x1"x3". Once casted I found that the subastance was too wet to make a sound. Over time the moisture fell out of the substance and could make a slight sound. I believe because of this that cooling the sugar glass in a refrigerator will make it harder and able to make a better sound.

Although I had lengths given to me for use on the previous website, I didn't have the proper lengths for the substance I was using. This website gave me the mathematical formula to decypher the proper dimensions and factors of the xylophone.

I accessed this website before I formally started the project for an example of xylophone construction. I currently use it for a frequency list. This was back when my focus was on making the xylophone.

The short answer to the question about why the center of a xylophone bar is scooped out is that this increases the volume and resonance of the bar while decreasing the pitch. If, for example, the center section of a bar is one-half the overall thickness, then its pitch will be an octave lower than it would have been without the scoop.
