The cd does not state. There are 2 tracks: the relaxation track and the sleep track. Another one of her cds that is out of stock on amazon is 28 minutes for one track - this one is called clearing emotional clutter. I could not find this one for sale elsewhere and sorry, I am not going to listen to it to find out since the only cd player I have is in my car and the disc states do not listen to this cd while driving.
