Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Americans pronounce solo as SOH-loh (/ˈsoʊloʊ/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He went for a solo hike to clear his mind" or "She played a guitar solo that impressed everyone in the audience" — more examples below.
Record yourself saying "solo" and play it back. The mic stays on your device — nothing's uploaded.

Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.

Start with your mouth slightly open, then close your jaw slightly as your lips round. Shift your tongue back slightly, then stretch the back up.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch SOH — keep everything else short and quick.
