When you play a solo do you improvise and if you improvise how do you prevent wrong notes (yeah push the right key )?
Are the (solo)notes always in the note scale of the chord?

If you play a wrong note, quickly change to another note, so it sounds like a passing tone.
The solo notes would not be in the scale of the chord, they would be in the scale of the songs key. In pop music you would play notes in that scale, not necessarily in jazz and blues. Miles Davis - almost never.

hi Jan,
Rule #1 -- As long as you do not stop there are no bad notes, just passing tones. Allow your ear to guide your playing.
Rule #2 -- have patients, it will get better. After a while you think a note in your mind and then play it.
Rule #3 -- It is possible to make rules for put solo notes. General rules are possible. Remember the composer thought about the note and then tried to compliment the note with a chord - sometimes he made changes in the chord structure to match his melody note. I have heard to many soloist play with scales arps and rules only to sound boring and repetitive.
Play what you feel wow, what a way to go.

If you play a bad note smile and play the exact same bad note the next time. That way the listeners will think you did it on purpose and it wasn't a mistake.

If you play a bad note, just tell everyone you background is in Jazz. They'll go; "Aahhh"!
