If you’ve spent more than five minutes in a preschool classroom recently, you’ve probably seen a silver-haired man with a boundless supply of energy dancing on a screen. That’s Jack Hartmann. Specifically, his Jack Hartmann letter A content has become the unofficial anthem for four-year-olds across the country.
Honestly, it’s kinda fascinating. Why does a guy who’s been doing this for decades still dominate the YouTube algorithm in 2026? Most "educational" songs feel like they were written by a robot trying to mimic a human, but Hartmann’s stuff has this weirdly infectious, retro-cool vibe that just works.
The Science Behind the "A"
Jack doesn't just wing it. He’s actually got a BA in Child Psychology and an MA in Clinical Psychology. That’s the secret sauce. When he sings about the letter A, he isn't just reciting the alphabet; he's using something called multi-sensory learning.
Basically, he wants kids to see it, say it, and sign it.
His video "See It, Say It, Sign It | The Letter A" uses American Sign Language (ASL). Kids don't just sit there staring like zombies. They’re moving their hands to form the letter. They're making the /a/ sound for "apple." It’s a total workout for their little brains.

More Than Just One Video
When people search for Jack Hartmann letter A, they’re often looking for a specific style of video. He’s got a few different versions depending on what you’re trying to teach.
- The Uppercase Version: Focuses on the "big A." It uses Dr. Jan Richardson’s handwriting directions. Think: "Slant down, slant down, across."
- The Lowercase Version: Focuses on the "little a." It’s all about going "around and down."
- The Phonics Workout: This one is intense. It’s basically a gym class for vowels.
I’ve talked to teachers who swear by his "Letter A Song" because it covers both the short and long vowel sounds. Most videos just stick to "A is for Apple," but Hartmann dives into the nuances. He gets that kids need to know that A can sound like "acorn" too.
Why Teachers (And Parents) Haven't Burned Out
Let’s be real. Children's music can be annoying. Like, "stuck-in-your-head-at-3-AM" annoying.
Hartmann's tracks usually have a bit of a hip-hop, reggae, or Latin beat. It feels a little more like actual music. Plus, his wife was a kindergarten teacher, so he gets the classroom "vibe." He knows exactly when a song needs to speed up to keep their attention and when it needs to slow down so they can actually learn how to write the letter.

The 2026 Digital Impact
Even with all the new AI-generated kids' content flooding YouTube these days, the Jack Hartmann letter A videos still pull millions of views. Why? Because you can’t fake the genuine connection he has with the camera.
He’s a real person.
In a world of "CoComelon" clones, there's something comforting about a guy in a bright t-shirt who looks like he’s actually having fun. His videos are often used as "brain breaks." These are the short intervals where kids get to move around so they don't lose their minds during a long lesson on phonics.
Actionable Tips for Using Jack’s Videos
If you're a parent or a new teacher, don't just hit play and walk away. Here is how to actually make the letter A stick:

- Do the ASL signs with them. If they see you doing the thumb-to-the-side "A" sign, they’re 100% more likely to copy it.
- Use "Sky Writing." While Jack is demonstrating the strokes in the air, have your child do the same thing. It builds muscle memory before they even pick up a pencil.
- Find the "A" in the real world. After the song ends, go on a "Letter A Hunt." Look for apples, ants, or even the letter A on a cereal box.
The goal isn't just to memorize a song. It's to build a foundation for reading. Jack Hartmann just happens to make that foundation a lot more fun to build.
Next time you hear that "Let's Learn About the Letter A" intro, don't roll your eyes. Just lean into the "slant down, slant down, across" and enjoy the fact that your kid is actually learning.
Actionable Next Steps: Start by watching the "See It, Say It, Sign It" version of the Letter A video. It's the most comprehensive for beginners. Follow it up by having the child draw a large letter A in a tray of sand or salt to reinforce the tactile learning Jack emphasizes.
