Create compositions and practice music theory with Composia. Export your creations to MIDI or PDF.
Composia is a project I started in order to apply music theory concepts - and help me learn them.
There are a number components that I've had to build: theory, database, sheet music generation, menu system, and synth.
- Theory
So far I have programmed in Keys, Solfege, Scales, Chords, Phrases, Figures, Compositions and Part Writing. Getting the part-writing to work was very challenging. It doesn't follow the rules 100% in order to allow the user some more freedom to create.
- Database
I had to create a way to store compositions in such a way to retain context and allow AI to use for generation in future versions.
- Sheet Music Generation
The most difficult part so far has been the sheet music generation & exporting with realtime pinch zoom. At first I thought it wouldn't be SO complicated but turns out allowing for 4 voices and all the variations of notes and rests is very tricky. There is still a lot to do but it's at least stable now.
- Menu System
Since I had to keep creating different menus to test various aspects I decided to go with a "neuron" menu system. This was also a giant pain to build but has made things easy once it was put into place.
- Synth
This is currently the weakest part of the project, but it produces a basic sound for the notes. I decided to use overtones to make a note sound louder. The louder the note the more overtones are attached.}

This is version 2.0 of Music Box AI. I have changed the app name to Composia and drastically improved the capabilities. I've had to strip the AI aspects for now but they'll be returned and be much more powerful in later versions.
