Guitar soloing is really just improvising single note lines over a chord progression. You lean on scales, arpeggios, and rhythmic phrasing to build a melody in the moment instead of playing something written out ahead of time. Strong soloing comes down to ear training, a working vocabulary of licks and patterns, and enough technical control that your fingers can actually keep up with what you're hearing. It's also about listening: to the bass, to the changes, to your own phrasing, so what you play connects to the music instead of just sitting on top of it. Building this skill mixes structured practice (scales, arpeggios, technique drills) with looser, more exploratory playing, where you mess around with phrasing and vocabulary until it starts happening on its own.
Where Soloing Vocabulary Actually Comes From
A lot of players treat soloing and comping like two separate skill sets. They practice one and let the other slide. Some MMC instructors point out that the ideas you're already using in your lines can double as raw material for your chords, so the work you put into soloing pays off twice.
I started to think about using the things that I do in my soloing for my chords.

This same instructor talks about an early focus that shaped a lot of his soloing habits: chasing the phrasing of horn players instead of settling for licks that just fall under your fingers on guitar.
I would practice scales, arpeggios, and I put a lot of focus into wanting to sound like a saxophone player and guitar players that were able to string together long phrases and that was my primary focus.

Language, Vocabulary, and the Limits of Teaching a Solo
No solo really works as a formula you can teach note for note. It comes out of internalized language that gets applied a little differently every time you play it. One instructor working through a standard makes this point directly while breaking down an improvisation built on bebop phrasing.
And the last element that I want to talk about, I guess, which I demonstrated here in this improvisation, and of course I can't teach it in any great length, is to develop a basic skill or basic vocabulary in the language of bebop.
— Jake Reichbart, Out of Nowhere Masterclass
That vocabulary only becomes usable once you've heard it, repeated it, and sat with it long enough that it surfaces without you thinking about it mid-solo. That's probably why lessons built around full course breakdowns, like the Out of Nowhere Masterclass, spend so much time on phrase by phrase analysis instead of isolated licks.
The Technical Side of Soloing
Vocabulary and good ears matter, but soloing hits a hard technical ceiling if your left hand can't execute what your ears are hearing. Stretching, shifting, and finger independence drills aren't glamorous. You just woodshed them quietly, but they clear out the physical roadblocks that otherwise limit what you can even attempt in a solo. On working through demanding stretch exercises, one instructor is pretty direct about the approach.
the stretches, what I would do with these is I would play them slow. I would definitely work with a metronome.
— Joe Pinnavaia, Guitar Techniques Builders
Slow, metronomic repetition isn't exciting, but run it slow enough, often enough, and it's what makes fast or wide interval ideas playable in real time instead of falling apart the second you push the tempo. Courses like Guitar Techniques Builders exist specifically to close the gap between what you hear in your head and what your hands can actually produce right now.
Putting It Together
Guitar soloing improves fastest when technique, vocabulary, and listening get trained together instead of in isolation. Scales and arpeggios give you raw material, technical drills give you the hands to execute it, and transcribing or absorbing real language gives you something worth playing in the first place. For a broader set of structured lessons on this, it helps to work through material organized around improvisation and soloing, since the skill rarely develops from any single exercise on its own.
Treat solos as language, not formula. Build vocabulary on purpose, keep the technical drills unglamorous but consistent, and let your ear guide the phrasing decisions in real time.
