Toccata is a piece about decay, about the impermanent. The emergence over time or, rather, progression of entropy is a key characteristic of our universe. Everything evolves to nothing. We as mortal beings have sometimes trouble reconciling with this idea. Humans have sought immortality for millennia, be it through ancient potions or modern medicine, be it from leaving a legacy that we feel will stand the test of time. It will, only to decay later than us.

Toccata is a piece about change. Change lies at the heart of human cognition and human nature. Our thoughts and our emotions happen over time, and are a function of the change that is both around us and at the very core of our selves. Change comes in nature in cycles. Seasons of growth, seasons of ripe fruits of life, seasons of decay, of death, rebirth.

Toccata is music. We find music to convey some of the deepest streams of human condition, connecting it to some other form of being. Music also happens over time, and music happens because of change. Music encodes our feelings better than any other aid we may have. Toccata incorporates this at its very core, as the main sound is Andreas' family piano where he learned to play, sampled this past July.
