Audiation is a musical term created by Dr. Edwin Gordon. Audiation basically refers to singing a tune or rhythm in your head without making any sound with your voice or body.

       "Audiation is the foundation of musicianship. It takes place when we hear and comprehend music for which the sound is no longer or may never have been present. One may audiate when listening to music, performing from notation, playing “by ear,” improvising, composing, or notating music " - Edwin E. Gordon

      For many years, even before I started teaching Music Together®, I encouraged my private students to listen carefully, then sing a melody before they tried to play it.  Little did I know that I was encouraging audiation.  In order to sing in key, we have to be able to audiate.  Often, when learning a new instrumental piece, I sing it to myself or audiate the piece before trying to play it.  If it is implanted in my brain through my voice, I can then transfer it to my fingers.  Children can learn to audiate by singing a familiar song then singing it again leaving out a line or two but audiating so that when you start singing again, you pick up right in the perfect spot - without even missing a beat.  This works great with songs that have hand motions.  Try it at home.  It's fun and helpful to your child's and to your music development.
