Objectives Hand in your Final Project outline Make a one-string bowed instrument similar to an erhu Practice Scales Work on your composition

Making a One-String Erhu Okay, I know erhu means 2 string fiddle, just use one string for now, it will be easier Construct the body from a tin can or small plastic container Punch a small hole in the closed end of the container, a little toward the edge

Making a One-String Erhu Thread the string through the hole Make a bridge, put it on the container, and thread the string over it Make a neck out of stiffened cardboard and attach it to the container Attach the string tightly to the end of the neck

Making a One-String Erhu Make a bow with several pieces of string over a stiffened piece of cardboard and two cardboard bridges The string should be very tight All the pieces should make a flat surface

Making a One-String Erhu Try to play the instrument with the bow and make any adjustments needed to get a sound Try to play the major and minor scales on your instrument –If you are not familiar with how the scales should sound, you can sequence them in CoolEdit and listen to them

Pythagorean Minor Scale in CoolEdit Open any pitched sample you have in Cool Edit (first make a backup copy of your sample!) Follow the procedure you used last week to make the Pythagorean Minor Scale in CoolEdit –To calculate the ratios for the Pythagorean scale, generate a series of perfect 5ths by multiplying by 3/2 SAVE the minor_scale.wav file

Playing the Scales Listen to the scale you made in CoolEdit and try to play it on your instrument

Composition Continue working on your composition –Keep writing program notes about your ideas as you work on your composition so you will remember them –the program notes template is on the Web
