Raise the back of your tongue to touch the soft palate. Add vocal cord vibration, then release.

Americans pronounce gracefully as GRAYS-fuh-lee (/ˈgreɪsfəli/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The jellyfish drifted gracefully through the water".
Record yourself saying "gracefully" and play it back. The mic stays on your device — nothing's uploaded.

Raise the back of your tongue to touch the soft palate. Add vocal cord vibration, then release.

Curl or bunch your tongue without letting the tip touch the roof of your mouth. Brace the sides of your tongue against your upper back teeth, and round your lips slightly.
Start with your jaw slightly open and the front of your tongue forward and slightly up. Glide upward, your jaw closes a little more and your tongue arches higher toward the roof of the mouth.
Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

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 GRAYS — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
