First, we must get a few small (but important) details out of the way. One concept which we will refer to often is the idea of finger numbers. Using finger numbers, I can easily communicate to you which fingers should be used to play the written notes. The numbers of each finger are as follows: The thumb of each hand will be 1. Number your fingers outward, until you reach number 5, which will be your pinkies (See Picture Below). This method of numbering is universal, and used in all types of music.
