Arduino Plays C Harmonic Minor

Got some new components today including some force sensitive resistors, and a speaker.  So I reworked my code that controlled some LEDs with a 1k potentiometer to select different notes in a scale, instead of different LEDs.  Next, I'll be working on some improvements to this function.  As soon as I get some terminal locks I'll hook up my soft pot resistor in place of the potentiometer knob.  I also want the pitches to change smoothly in real time, as opposed to abruptly switching to the next note in the scale.  Not gonna post the code because it wastes so much space, but if anyone wants to see it I can send it out to you.
