Using the sample code for the "Case of the Missing Fundamental", use CLM to create a simple melody of your choice with just higher harmonics (no fundamental). Hint: there is a function available to translate from pitch names or midi numbers to frequency in hertz... try evaluating "(pitch 'a4)" in the lisp listener... Browse through the CLM Manual.

Here are the examples: a CLM instrument that can be used to generate a sinewave of arbitrary frequency and amplitude (sine.lisp) and the file that was used to create the missing fundamental examples (missing-fundamental.lisp). To recreate the example:
