Play[f, {t, t_min, t_max}] creates an object that plays as a sound whose amplitude is given by f as a function of time t in seconds between t_min and t_max.

Pure functions. When you use functional operations such as Nest and Map, you always have to specify a function to apply. In all the examples above, we have used the "name" of ...
