My instrument was a xylaphone/percussion instruments, I was made of hard wood and suspended in the air using fishing wire,
I could play the following notes: C4, D, D#, F, F, G, A#, B as you can see, 2 noptes both played F which was a design flaw from how I cut them both being to small, leading to practically same note. It had frequency range from 2040Hz to 4000Hz, The blocks were 19 1/2 cm, 19cm, 18 cm, 17cm, 16 ¾ cm, 16 ½ cm, 15 ½ cm 14 cm 13 ½ cm
I remeber the process of building it, day one was crucial, Beacause i was sick that day,and day 2. but the rest of the days I was working hard, First day (back) I made The peices of Wood I needed, day 2 put them together, day 3 was cutting the note blocks, day 4 was getting the blocks on the fishing line suspended in the air and day 5 it was finished
