There are a lot of people who could advice you a lot better than me on this issue.
But, for example.
Take 5 notes from the pentatonic scale. Play them in a context of a solo and remember their rhythm value and how it cooperates with the backing track. Then repeat the same value of rhythm with other notes in the same solo. Then try to divide that rhythm in half. Etc etc…
it’s a completely wide topic to discuss and I can’t be too helpful for you
