Hi,
I probably copy this from somewhere when I was doing my research on improvisation some years ago. Check it out.
1. Listen to what you want to learn (genre).
2. Learn the melody.
3. Play the 3rd, 5th, 7th of every chord - don't start on the root note.
4. Transcribe a solo or melodic fragments, Learn or transcribe all or part of a solo. Pick one that is attractive to ear and playable.
5. Soloing is a language, just like talking. Let the music breathe.
Hope this is helpful.
