you defined a class and the things right in the class-definition are executed when (point in the code) the class is defined
so you should better do something like:

class Backgroundmusic:#load background music and play
    def __init__(self)    
        self.music = base.loadMusic('sounds/The_Amulet.mp3')
        self.music.setVolume(1)   #Volume is a percentage from 0 to 1
        self.music.setLoopCount(0) #0 means loop forever, 1 (default) means
        self.music.play()
22 
class Backgroundmusic:#load background music and play
    def __init__(self):   
        self.music = base.loadMusic('sounds/The_Amulet.mp3')
        self.music.setVolume(1)   #Volume is a percentage from 0 to 1
        self.music.setLoopCount(0) #0 means loop forever, 1 (default) means
        self.music.play() 

m=Backgroundmusic

Ok I switched to this and now no music will play- I looked up other examples and it appears correct, looked in my book and it appeared correct- so why doesn’t this make music when the:

class backgroundmusic(object):

without the

def_init_(self):

does play it.

I tested the code with my gui’s and it works right but why not the music?

I have a 64bit system, I wonder if that is causing the sound clitch?

Replace this line:

m=Backgroundmusic

with this:

m=Backgroundmusic()

The former is simply assigning m to the Backgroundmusic class object; it is not creating a new instance of Backgroundmusic, and never calling your init() method.

The latter is creating a new instance of Backgroundmusic, which calls your init() method.
