1. A scripting language, designed to be embedded in other programs, emphasis on web templating. C++20, Flex, Bison, Unicode, Unit Tests, Doxygen, Github, Docker compilation, and a YouTube series over its development and explaining how everything fits together. I'm almost done with my 1st draft of the language (6k lines of code, 3k lines of comments), after which I'll begin recording.
2. I record hymns in congregational style, as the traditional pianists used to play for church services. I'm focusing on public-domain hymns, re-typesetting them using Lilypond, and including the choral music as an overlay with an overhead shot of my hands playing. I don't care if I make money. I believe that this playing technique (improvisation based on 4-part vocal music) must be preserved, and I'm trying to do so.
3. I am planning on recording an instructional course (available for free) to teach how to play in the evangelistic church pianist style. Using my approach, I have had adult students go from "never touched a piano or read music" to "can play a hymn for church with the big, full sound of the evangelistic style" in 3 months. Again, I believe that this style needs to be preserved, and I've seen a lot of the existing materials (and even bought them myself to evaluate, to the tune of thousands of $$$ spent), and I'm greatly disappointed in what is available. I teach technique and theory (I have a BMus in piano performance from a state university), and I really don't care to teach classical piano. I would rather teach church musicians.
