Graphical Notation is an app for music creation and graphical notation using Artificial Intelligence. The coreof Graphical Notation is the CalmusAI brain where the modern composing methods are programmed into the brain using Lisp programming language. NASA has historically used Lisp for artificial intelligence and autonomous systems, most notably in the 1990s Remote Agent project, the first AI system to control a spacecraft. CalmusNotation does not collect or use any musical material from the internet but creates new music based on the input from the user. In addition - CalmusNotation can also receive composed music from CalmusComposer and CalmusPlay - and present the music as graphical notation for live performance - in real-time. CalmusComposer composes music with Artificial Intelligence and can send the musical result to GraphicalNotations to be presented for life performance. CalmusComposer is connected to GraphicalNotation through WiFi local network - by selecting CalmusNotation in Settings.
