You’ve seen it. Maybe it was a grainy video of a preschool graduation or a high-definition clip of a professional performer at a jazz festival. Louis Armstrong’s gravelly voice begins to crackle through the speakers, singing about green trees and red roses, and then someone starts to move. But they aren't just dancing. They are using their hands to paint the "colors of the rainbow" in the air.
What a wonderful world sign language interpretations have become a massive cultural touchpoint. Honestly, it’s one of those rare things on the internet that almost everyone agrees is actually good.
But there is a lot more going on here than just "pretty hand shapes." When people look for these performances, they’re usually searching for a specific kind of emotional connection that spoken language sometimes fails to hit. It’s about the bridge between the hearing and Deaf worlds, sure, but it’s also about how American Sign Language (ASL) functions as a visual-spatial language that can actually make a song feel bigger than it does on a record.
It’s Not Just Translating Words
A common mistake people make is thinking that sign language is just a word-for-word swap. Like, you see "green" and you do the sign for "green." That's not really how it works in a high-quality performance.
ASL has its own grammar. It has its own syntax. When an expert performer takes on a classic like "What a Wonderful World," they aren't just coding English into hand signals. They are using classifiers to show the size of the trees. They use their facial expressions—which are actually grammatical markers in ASL—to convey the "bright blessed day" and the "dark sacred night."
If you watch a performer like Amber Galloway Gallego, who is famous for her concert interpretations, you’ll notice she doesn’t just stand there. She’s vibing. She’s showing the timbre of the instruments. In the context of this specific song, the "wonderful world" isn't just a statement; it's a visual landscape built in the three-dimensional space around the signer's body.
Why This Specific Song?
Why do we see so many what a wonderful world sign language videos compared to, say, upbeat pop songs?

It’s the tempo.
The slow, deliberate pace of the track allows for incredible "sign-singing" or ASL poetry. In ASL, you can vary the speed of a sign to show intensity. A slow, sweeping motion for "clouds of white" feels like the clouds are actually drifting. You can't really do that as effectively with a 140-BPM techno track.
The Cultural Impact of the 1967 Classic
Louis Armstrong recorded this in 1967 during a time of intense racial and political tension in the United States. It was meant to be a healing song. When you add sign language to it, you’re adding another layer of inclusivity. You’re saying that this "wonderful world" belongs to the Deaf community, too.
It’s also a staple in schools. Many hearing children learn their first signs to this song. While that’s great for awareness, many Deaf advocates, like those involved with the National Association of the Deaf (NAD), point out that there’s a difference between "school signs" and true ASL. Hearing kids often use Manually Coded English (MCE), which follows English word order. True ASL is more cinematic. It’s more fluid.
The Technical Artistry Behind the Signs
Let's talk about the "colors of the rainbow" line.
In a standard translation, you might just sign "colors" and "rainbow." But in a poetic ASL version, a signer might use their fingers to trace the arc of the rainbow across the sky, then transition that shape into the signs for the people passing by. It’s a literal visual metaphor.

- Spatial Mapping: The signer "places" the trees on one side and the roses on the other.
- Non-Manual Markers (NMMs): The raised eyebrows and the squint of the eyes tell the story as much as the hands do.
- Conceptual Accuracy: Instead of signing "I see," which implies a literal physical act, a signer might use a sign that indicates "noticing" or "appreciating" the beauty of the world.
It’s basically 3D storytelling.
Misconceptions You Should Probably Know
A lot of people think sign language is universal. It’s not. If you’re watching a what a wonderful world sign language video from a performer in the UK, they’ll be using British Sign Language (BSL), which is completely different from ASL. They even use a two-handed alphabet!
Another thing? Not every Deaf person loves these viral videos.
There is a long-standing debate in the community about "Sign Language Music Videos." Some feel that hearing creators often use ASL as a prop for "clout" or to look "inspirational" without actually supporting Deaf creators or understanding the culture. This is why it’s so important to seek out Deaf performers—like Justina Miles or Shaheem Sanchez—who bring an authentic cultural lens to the art form.
How to Actually Learn the Signs Correctly
If you’re moved by these videos and want to learn the song yourself, please don’t just copy a random TikToker. You’ll probably get the parameters wrong. A sign is made up of five parts: handshape, palm orientation, location, movement, and facial expression. If you get one wrong, you might be signing something completely different. Or just gibberish.
- Check out Hands Land: They focus on ASL rhymes and rhythms.
- Look for Deaf-led tutorials: Search for "What a Wonderful World ASL Deaf" to find native signers.
- Learn the "Why": Understand why a specific sign is used for "blessed" versus "holy."

First, go watch the performance by the Deaf Professional Arts Network (D-PAN). They have been pioneering high-quality music videos for years that are made by and for the Deaf community.
