As I said before my Dad’s first instructions to me for improvising were “embelish” the melody like Louie Armstrong. That great advise has carried me all the way. I improvise with no knowledge of harmony or chords and I am not even aware of what key I am playing in. I hear the lines I want to create off the changes inwardly before I actually play them and the melody of a song is a key factor. As I weave my lines over the changes I will land on certain melody notes. Those melody notes are the guide posts that connect the dots of the solo in a “horizontal” manner. Even if I take it “out” a bit away from the melody I am still aware of the melody inwardly. Because the solo is very connected to the melody, “Lyricism” is acheived in the solo which is so important to me, something that could get lost when just playing patterns or licks. If you listen to the greats of the golden age of vintage jazz from Louie Armstrong through Charlie Parker you will definitely hear lyricism in their solo lines.
