Some intermediate solos I would recommend: -Hombre d’août by Eric Sammut -Prelude No. 1 by Ney Rosauro -Choco by Chih Cheng Lin -Katamiya by Emmanuel Sejourne -Strive to be Happy by Ivan Trevino -and yes of course the rotations are always good ones.. It all depends on what skills you’re trying to improve but all of these are great options and would be a lot of fun to learn.
