bs.sleep(1/2)                            //Sleep for 1/2 second
bs.beep('C#4', 1/4)                      //Play note C#4 for 1/4 second
bs.sleep(1)                              //Sleep for 1 second
bs.beep(500, 1/2)                        //Play 500 Hz for 1/2 seconds
bs.sleep(0.5)                            //Sleep for 0.5 seconds
bs.beep('Eb5', 2)                        //Play note Eb5 for 2 seconds

bs.seq([                                 //Play a sequency of beeps and sleeps
	[440, 1],                            //A beep is an array with note or frequency and duration
	1/2,                                 //A sleep is a number
