Instruments are fun!
Homemade ones more so, and ones that look and sound as if a violin and a bass were thrown off the empire state building, landed in a tuba and run over by a taxi and a humpback whale* are the most fun.

So, lets make one!

This is more of an instructional instructable then specific instructions on how to build my instrument.

*I adopted a whale, though if he runs over tuba's is uncertain

Step 1: Materials

What you need (for a stringed instrument, which is what we will be making):
  • Strings (Golly!) Rubber bands work fine.
  • Resonant chambers. They amplify the sound. Technology known as "Altoids Tins" work well.
  • Materials. Whatever you're going to build the structure from. I used (gasp) Knex, because they were in a bucket between my feet at the time of writing.

Step 2: Dont plan!

Sit around and don't plan your instrument.

Step 3: How many strings?

Randomly decide (no planning!) how many strings you will have. For this, I'm choosing 4- to match my cello.

Step 4: Build frame

This bit is pretty easy. Simply create a frame to stretch your rubber-band strings taut enough to be played. Don't worry about pitch, we'll fix that when we string the bands.

Step 5: Add extra's

I HATE changing positions when playing cello, so I've made all my instruments so far with movable bridges. You slide them up and down the frame to change position, instead of sliding your hand. So I added that.

Step 6: String your strings!

OK, here's The slightly fun part. Pick out however many rubber bands as you have strings, and put them together. Take one, and attach it to the lowest part of your instrument- which part holds the low string, then twirl it around until its twisted up into a single strand. Attach to the other end of the instrument. Repeat with the other strings, but before attaching wrap it around the end a few times to make it higher. E.G. the first string isn't wrapped at all, the second wrap two or three, the third four or six, etc. Just look at the pictures if you're confused.
So great and such a happy piece...need to whip up something fast for my son's class that he oooops forgot to mention was due on Monday...

I like how they are better than the usual 'lets tie a bunch of rubber bands to some sticks'. Anywho, time for some semi-relevant 70's music.

hahahaha this is awesome! the one with the red rods coming out is the best
