This soundtrack is a relaxation process that is based on breathing.  It is helpful when you first try this breathing process to use a small diameter straw that commonly comes with a latte.  The diameter of the straw is slightly more than 1/8 of an inch.  Breathe in through the straw and breathe out through the straw; do not breathe through your nose.  This will help you to achieve the desired effect of relaxation.  Listen to the soundtrack, and follow along with it.
