HOMEWORK!!!! ^_^

- homework -

Yep, you heard me right, homework.

Today's assignment is to use what you have learned in the previous posts about finding the length of a flute according to the desired fundamental note, in making something new - to make this thing, you will need one more quick lesson - here goes;

Now, we know that for open-ended flutes, the flute's body's length is roughly equal to ONE-HALF the wavelength of the particular fundamental note you want.

We also know how to define the length of said wavelengths, by dividing the speed of sound in inches (again, at sea level, and at roughly 70 degrees F, this is 13,526.5 inches per second), by the number of Hertz (cycles per second) of the note in question.

One other thing to know here is, that closed-ended flutes (those that are like upright tubes, covered on the bottom, and blown across the tops like blowing across a beer bottle top.... like the Andes "pan" flute) have to have their airflows go into the flute, to the end, and out again - so that means that their body lengths should be roughly ONE-QUARTER of a wavelength long.

So, your assignment now is to make a set of South American Andes pan flutes - a set of 12 pipes, PVC with caps on the bottom (or corked), and chromatically tuned.

This means that you will have one for each note - A, A#, B, C, C#, D, D#, E, F. F#, G, and G#. Using a couple of sticks, or pieces of PVC, or what have you, lash them all together.

For the blowing edges, bevel them for clearer sound - from the outer wall surface, towards the inner.

There will be some things to go over, and perhaps more learned, once you have completed this project.

Okay, have fun with this assignment! Until tomorrow, have a nice night! ^_^
