Sans doute que d'autres te donneront davantage de précisions à ce sujet, mais personnellement je crois que tu as toute liberté puisque le "ton", la progression d'accord est donné. À l'oreille donc (en ayant comme base la suite d'accords et la gamme).
Il ne faut pas confondre "analyse" et "création". L'approche théorique, c'est pour prendre des raccourcis, communiquer, te donner des repères, mais la langue ce n'est pas sa grammaire.
Si tu as la chance de "tomber" sur la vidéo de Victor Wooten "Groove Worshop", il y parle très bien de l'importance très relative (sinon mineur) du choix des notes dans un solo. Ça a l'air étonnant comme ça, mais en 2 minutes on comprend qu'il a tout à fait raison...

Genre: Fusion (Master Class)
Description
Master Bassist Victor Wooten lays out his philosophy of teaching and learning music in Groove Workshop, a brilliant master class captured on DVD by Hudon Music. While traditional music education focuses on technique and 'playing the right notes', Victor delves deeper and emphasizes many subtle and rarely taught aspects of music making, giving the viewer an incredible insight into his musical concepts.
Working with a master class of six Bassists, each with Bass in hand, Victor - along with expert Bassist and instructor Anthony Wellington - explores the following intriguing concepts:
* Notes: is it possible for wrong notes to sound great?
* Grooving: what elements need to be present for a good groove to happen?
* Articulation: how can you use articulation to better express yourself?
* Technique: should you be conscious of your technique?
* Emotion/Feel: are you able to make the deepest connection with your listeners - the emotional connection?
* Dynamics: how are dynamics critical to drawing in your listeners or pushing them away?
* Rhythm/Tempo: what are some specific exercises to improve your time?
* Tone: how can tone make people dance?
* Phrasing: how can you use your imagination to improve your phrasing?
* Space/Rest: why is silence so important in playing music?
* Listening: learn why for Victor, listening is actually the most important aspect of playing music.
