Music Note Sudoku

I often encourage students to practice randomized chord patterns by picking a chord type or two, and then moving them through a tone row.

For instance CMaj7 - Ebmin7 - FMaj7 - F#min7 - Dbmaj7 - Dmin7 - BMaj7 - Emin7 - AbMaj7 - Bbmin7 - GMaj7 - Amin7.
And the opposite Cmin7 - EbMaj7 - Fmin7 - GbMaj7 - C#min7 - DMaj7 - Bmin7 - EMaj7 - Abmin7 - BbMaj7 - Gmin7 - AMaj7.

I had great breakthroughs in my playing working through newer chord types that I didn't realize were coming slower to my fingers than I thought, like min7(b6)'s and Maj7(#5)'s.  This idea is a variation on one from the wonderful book Metaphors for the Musician by Randy Halberstadt which I highly recommend to all jazz students- not only is it filled with great information, but it's super easy to read and engages your passion for playing like working with a good teacher does.

Recently this discussion led to whether there could be 12x12 sudoku-type puzzles, where a note wouldn't be repeated in a row, a column, or a "box".  Well it turns out this is actually a popular variation of the typical 9x9 puzzle.

I also found this variation using the actual notes on a staff, and this simpler version using solfege syllables.

Here is one I made where I basically replaced the numbers with the note names.

In case you don't want to solve it to practice these patterns, here is the solution.
