&gt;<i>This is neat, of course. Yet, being classically trained myself and a software engineer, both for 30 years, I have yet to find an alternative music notation system that would make me proclaim I would use it.</i><p>Emm, this is not an &quot;alternative music notation system&quot; meant for musicians to read music in.<p>It&#x27;s an entry method for writing MIDI (and therefore alo getting standard notation output).<p>&gt;<i>Someone more qualified on the subject can probably explain why it is our brains have evolved to be &quot;tuned&quot; for notation.</i><p>They haven&#x27;t. You&#x27;re just used to it. Tons of self-tought musicians can&#x27;t handle it, even though they&#x27;re virtuoso 
players on their own.<p>Besides, the brain doesn&#x27;t &quot;evolve&quot; in the Darwinian sense in the span of mere centuries that we have had our modern music notation. It takes tens of thousands of years for something like that -- and only if reading notation provides any evolutionary benefit to not reading it.
