| Phrasing can be helped by good technique from exercises in the right and left hands, but this is just because having a good technique can help you execute any ideas you have at any given time.
I get my phrasing ideas from solos I transcribe, and other musicians that I interact with. phrasing is something that takes time to develop, and something that you really need to dig deep into to understand.
I would start off with simple solos of artists that you love, taking short phrases and playing them along with the recording to get inside the artist's head, to start to know what they were feeling and thinking at that point by what they played.
When you have the phrase down with the recording, start taking it all around your instrument, developing it as your own, changing notes, changing time feels, and making as much out of those few notes as you can. You'll find that after a few months of doing this your vocabulary will have increased immensely, and you'll start to develop your own sound and way of phrasing. It's then your job to continue doing this throughout your career, constantly searching for new ideas and new language.

do you have sepcial exercices to work on, your left/right hands, and then put them together, or do just work it out by transcribing solos, and then playing along?
