I hope you find this helpful.
Practicing jazz vocabulary is a great way to develop your own jazz improvisation skills. Start off by copying phrases or licks. Work them into your own playing, discover why they sound good, rhythm, enclosures, approach notes... then work that into your own playing. The more you do this, the more you will start to understand how to construct your own lines and hear them when improvising!
Warm regards, Darren.
