I learned about frequency, and wavelength. My success was having the good sounding frequency. my failular was making all the chimes in line. and the challenge was getting all the copper pipes aligned. I would have used different string if i could so that way to make it look better. i would have painted it if i had more time too. and i would have made sure i had a good partner to do it.
