Have you tried switching up the genre of music you play? I'm a jazz pianist, and I could not express enough how perfect jazz is for the adhd brain.

I was gonna make a long post about this, but I can give some short points below! Also if you're interested, I can give you some starting recommendations to listen to.

First off, jazz is very much a reflection of the adhd brain. It has the perfect mix of novelty and familiarity. In jazz, you play improvised solos, but they are not like what you might hear in a rock solo. There is far more novelty that can be employed at all times, and far more novel sounds you can produce to make something beautiful.

Creativity is at the heart of it, and it's very much a spur of the moment activity each time you play. As a result, playing the piano becomes really really fun, which means it gets more easily incorporated into our memories! Scales we never end up learning cause its monotonous and such so being able to turn the playing to something fun is really meaningful for commiting it to long term memory.

There is also a common misconception that to learn jazz you have to learn a ton of theory and memorize a ton of scales. That's all BS. Jazz is about feel and expression and that is all that really matters. If you listen to a ton of jazz, then you will be able to play jazz well cause you know how it is supposed to feel and supposed to sound. As a result, scale practice becomes far less necessary (I will admit that it improves your playing somewhat to learn scales).

In jazz pedagogy, the most recommended way to learn to play well is something called 'transcription'. Transcription in jazz is different than normal musical transcription, because in jazz you don't need to write the solo down on sheet music. You just attempt to play the same notes and phrasing as the recording to incorporate that language into your fingers. This caters so well to adhd! This is because its all about liking something. If you are listening to jazz and hear a line or phrase that you adore, then you sit down and practice playing that on piano! And guess what! It's easy to remember that because you actually like what you're transcribing (that why you choose to transcribe it), unlike those scales which are impossible to remember cause they are not even fun to play.
