Learn to trust the music inside you...

Jazz pianist Harry Pickens has produced a masterpiece of soothing meditations and self affirmations accompanied by a calm, hypnotic musical soundtrack, designed to instill a sense of relaxation, confidence, and natural flow in your music and your life. Before we can bring chord, melody, and lyric into harmony, we must first bring harmony to our own mind, body, and spirit.
This method requires your full attention and open mind in a quiet, uniterrupted environment. Trust the music within you!
