ListPlay[{a_1, a_2, ...}] creates an object that plays as a sound whose amplitude is given by the sequence of levels a_i.
NHoldFirst is an attribute which specifies that the first argument to a function should not be affected by N.
Not
(Built-in Mathematica Symbol) ! expr is the logical NOT function. It gives False if expr is True, and True if it is False.
