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. GraphicalNotation is connected to CalmusComposer, through WiFi local network - by selecting the MacOS device in the settings of GraphicalNotation. CalmusNotation needs Internet connection. ## Key features - AI-powered music composition - Graphical notation display - Real-time performance visualization - Lisp-based AI engine - User input-driven music creation - Integration with CalmusComposer and CalmusPlay ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/calmusnotation/id993026661/reviews.md ### 1/5 — No Help file? *2024-10-04* Maybe I didn't look for enough, but when a click "Help" gets the note that there is no help available, that's an absolute no go. How do you expect people to learn your app without the benefit of a tutorial? ### 3/5 — Update Needed for Tablature *2023-07-23* This is a really great app for most musicians. The problem is that it’s pretty useless for guitar, ukulele, bass, and other stringed instrument players who don’t read standard notation. Most of us stringed instrument players read tablature. Is there any chance you’d consider updating the app to have the ability to switch between standard notation and tablature? It would be helpful to use alongside your other apps. Thanks for the consideration! ## Frequently asked questions about CalmusNotation ### What is CalmusNotation?
