/***************************************************************
 * Frequencies for an entire piano keyboard. We pulled this info
 * from this website:
 * http://www.phy.mtu.edu/~suits/notefreqs.html
 * 
 * Note names are organized by octave and sharp (s) or flat (b).
 *
 * Note: #define is a pre-compiler directive, so on the first pass
 * through your code, the compiler will replace anything that
 * has a #define statement associated with it with the appropriate
 * string or value. 
 *
 * Notice that #define does not use an '=' or a ';' mark.
 *
 * It's convenient because it doesn't use up any processor resources 
 * and the math is done by the compiling computer rather than on
 * the Arduino.
