A random tone is selected from the dorian scale every 4 beats (1 second).  This MAIN frequency is generated by a saw tooth oscillator.  We then divided by two to arrive an octave below and then generate this frequency using a square wave oscillator, this represents our bass.  Every two beats a triangle wave oscillator generates either the third of fifth above but wrapping around our scale so the notes may end up being lower than MAIN.  Together, these three oscillators represent our harmony.

Our melody is played two per beat.  In general, we meander up and down the scale never jumping more than one note away, and possibly staying on the same note, but once per measure we begin a new phrase starting from our MAIN frequency.
