Synthesize gentle electronic waves.  Congruencey verified.  /play commodore64synth.

Chiptunes are still in style.  As a ringtone, you must demand attention, give a sense of urgency.  So I copy and pasted the bit four times and sped each successive segment up 10%.

At this point, I feel comortable with using audacity.  For this coming week, unlike others, the biggest drawback will not be my inability to use a tool this time.  The biggest challenge is how I and JBC will use Audacity with skill and elegance.
