I'm not really sure what level you are at methodis, or if this really helps, but when I used to teach I noticed there is a period when you start using scales properly in improvision, but your improvising doesn't sound like a melody, more like scales going up and down. If that's you, some things I found can help:
- stick to just two, three or four notes and make a strong melody that repeats frequently, like in the verse of a song. Most listeners needs something for their ear to latch on to, otherwise they won't be attached to, or understand what you're playing. Keep coming back to it in your improvisation session and build around it.
- if you want to do a scale-like run, the context of it is important, but also how you begin and/or end it is fairly critical. If it just ends at the top of the scale, it'll tend to sound like a scale, but if the few notes after it are well chosen, it will become integrated into the melody.
