If you use a very short delay and modulate the VCO with a low frequency
triangle or sine wave, the resulting effect is what we call chorus.  What
happens is the delayed material is shifed up and down slightly in pitch and
when mixed with the unshifted signal the result is much thicker
harmonically.
