My achievement today was utilizing a chord within Reverie, into the jazz hit Autumn Leaves.
I shared in some forums that I play completely by ear, and the only reason I even started learning some "classical piano" was to improve my technique (prior to that, I only played non-classical). In the last year, as I've gotten exposed to Chopin, Liszt, Rachmaninoff, etc., I've been picking their chord progressions and integrating it into more modern stuff as well.
I have an innate ability to connect dots between songs (e.g., Canon in D paired with Vitamin C Graduation; Moonlight Sonata with Fantasie Impromptu, etc)., and most recently paired Liszt un Sospiro with the theme song from the show This is Us.
So it's reverse of what I've seen, where some folks will do a "jazz version of Chopin" I'm using the Classical pieces as inspiration 🙂
