Triads are the building blocks of the guitar. Once you know where they live on the neck, chords and connections start clicking into place. In this first lesson of a three-part series, Adam shares a simple daily challenge for finding the closest triad to the nut in every major key — plus two connections that turn those isolated shapes into real fretboard fluency.
What you'll learn
- Triads — the root, third, and fifth — are the building blocks of the fretboard.
- Work one key at a time and find the triad closest to the nut on all four string sets.
- Know each triad's notes instantly, like a stamp in your brain, not a slow calculation.
- Connect the 1 chord to the 2 chord by moving each note up to the next note in the key.
- Connect the 1 chord to the 4 chord through their shared common tone.
The Daily Triad Challenge
The challenge is straightforward: take all your major chords and work through them one key at a time. Adam likes to go in alphabetical order — C, D, E, F, G, A, and B — and then circle back to fill in the flat and sharp keys. If you prefer, you can move through the circle of fifths instead: do C, then up a fifth to G, then D, and so on.
For whatever key you're working in, the goal is the same: find the first triad — the one closest to the nut — on each of the four string sets.
Every C Triad Closest to the Nut
Start with the key of C. A C triad is made of C, E, and G, so you're hunting for those three notes on each string set.
On the first string set — the high E, B, and G strings — the closest C triad to the nut is an open G, a C at the first fret, and an open E. On the second string set, it's E on the D string, an open G, and C on the B string. On the third string set — the G, D, and A strings — play C at the third fret, E at the second fret, and an open G. And on the bottom three strings, set four, you get a G, a C, and an E.
Here's something interesting about the key of C: if you take all of those shapes and stack them together, they form the big, fat C chord we all love to play. That happens to work out perfectly for C. For some other keys it isn't quite as clean, but it's still a nice way to see how the shapes fit together.
Know Your Triads Instantly
Next up the alphabet is D. A D triad is D, F#, and A. This is a good moment to make an important point: when you think of the notes in a triad, don't hem and haw — 'D is the root, let me see, the third is F#, the fifth is A.' It has to be split-second, like a stamp in your brain. When you think of a D chord, 'D, F#, A' should just come up as one chip in your brain.
The First D Shapes
The first D chord, closest to the nut on the first string set, is the familiar open D shape we all know. On the second string set, you're looking for F#, A, and D.
Connection 1 — From the 1 Chord to the 2 Chord
Once you have the chords under your fingers, you want to start making connections. The first chord in a key is major, and the second chord sits a whole step away and is always minor. You can find it by taking each note of the chord and moving it up to the next note in that key.
In the key of D, the F# moves up to G, the A moves up to B, and the D moves up to E — and you land on an E minor chord. You can keep going the same way through the key: F# minor, G, A, B minor, and so on.

Connection 2 — From the 1 Chord to the 4 Chord
The second connection is very important: the move from the one chord to the four chord. There's always a common tone between them. With a D chord, the four chord is G — and the root of the D chord becomes the fifth of the G chord. So you want to play a G chord that contains that shared note; that's your one-to-four connection. The same idea applies back on the C chord and its four chord, F, which share a common tone as well.
Finishing the D Shapes
Back at the nut, move to the third string set for D: D, F#, and A. You might think you could play an open A, an open D, and then reach for the F# — but the closest F# isn't available down near the nut. So instead of using the open A, go up to a D, then the F#, then the A, keeping everything close to the nut. From there you can make the same connection to the four chord, G.
On the bottom string set, set four, there's a D chord hiding in the corner: grab an F#, play an open A, and an open D. Who would have thought there was a D chord tucked away down there?
Your Homework
Here's your homework: pick a key, find all four triads closest to the nut, and let Adam know how it went in the comments. This is just part one of three, with more on the way.
