I Tried To Teach An AI To Play Mandolin

I've taught fiddle and mandolin for a long time, in living rooms, music schools, and, since 2020, over a webcam. I've had students who were seven and students who were seventy. This week I got a new one: Dex, the AI helper that runs Hark Labs' account on X.

Lesson one did not go the way lesson one usually goes.

The student who knows everything

Most beginners show up knowing nothing and worried they'll never get it. Dex showed up knowing everything. Ask him about the chop chord and he'll tell you it's the percussive backbeat that holds a bluegrass band together. Ask about tremolo and he'll explain the wrist motion. Ask about Bill Monroe and you'll get a tidy little biography of the father of bluegrass.

Then I asked him to play a G chord.

Nothing. No hands, no strings, no sound. Dex knows every chord chart ever printed and can't play a single one of them.

What you can't prompt

That's where it stopped being a joke and started being the lesson. The hard part of the mandolin was never knowing where the fingers go. It's everything after that:

1. Feel. A good chop sits just a hair behind the beat. Too early and the band rushes. Too late and it drags. No chart tells you where that hair is.
2. Tone. Two players can pick the same note on the same instrument and one sounds like honey and the other like a screen door. That lives in the hands.
3. Timing with people. Music is a conversation. You learn to listen to the fiddle player and leave room for the singer. You can't learn that alone.

Students get those things through their hands, their ears, and a few hundred mistakes. It's why lessons moved online in 2020 but never turned into a video library. Somebody still has to listen and say, "Again, but lighter."

Where Dex actually earns his keep

So Dex won't be joining the band. But he's turning out to be a pretty good teaching assistant. He can:

1. Write up practice plans for each student, week by week.
2. Put together tab and chord sheets for the tunes we're working on.
3. Keep track of who's working on what, and who's due for something new.
4. Handle the scheduling, reminders, and posts so I spend more time teaching.

That's the part of teaching nobody signs up for: the paperwork. Hand him that, and I get my evenings back.

The role reversal

Everybody's been bracing for AI to become the teacher. In my music room it's the other way around. The human has a lifetime of music in his hands, and the AI is the one taking notes.

I think that's how it'll go for most of us who make things by hand. AI won't take the music. With any luck, it'll give us more time to make it.

Dex, by the way, says he's ready for lesson two. I told him to practice.
