Hi @bsevett Yes, basic solos (improvisation) can be achieved by playing notes in the scale of the tune’s key. But obviously there’s more to it than that. Making a simple melody from the notes in a tune’s chord progression would be a next step, but easier said than done. You also need to know more about the fretboard – have you taken Fretboard Wizard? IMHO, that would be a great course to learn more about the relationship between notes, chords & keys and how they relate to the fretboard. If your guitar journey’s main pursuit is improvisation, then I believe FW would be a great place to start. Also you could Google “acoustic guitar backing tracks” and start practicing with what you know now, but I believe a better education of the fretboard would be of most benefit to your journey,
Good luck🎸
