Guitar triads

See the whole fretboard in small chord shapes. Now with guided lessons — free for major and minor — plus 6th and 7th chords in every key.

The fretboard gets easier when you can see the small chord shapes inside it.

Guitar triads is a practice app for learning triads, 6th chords, and 7th chords across the neck. Not as diagrams to stare at. As shapes you actually drill, hear, and move through in time.

If you already know open chords and barre chords, this is the next layer: smaller voicings, cleaner movement, and more options when you comp, write, improvise, or learn songs by ear.

Practice one chord everywhere

Choose a root, chord quality, and string set. Guitar triads shows you the inversions of that chord across the neck, then cycles through them at your tempo.

Use it to stop learning one grip at a time. See where the same chord lives on different string sets and in different positions.

Practice chords inside a key

Pick a key and work with the chords that belong together.

Run the diatonic chords in order, or drill common progressions like I-IV-V, ii-V-I, I-V-vi-IV, and minor-key movements. Stay in one fret range, or move through the neck as you play.

Go beyond basic triads

Triads are the foundation, but the app does not stop there. Pro includes 6th chords and 7th chords, so you can practice richer voicings and start hearing how those colors fit into real progressions.

Guided lessons

Use short lessons to understand what you are practicing, not just where to put your fingers. Learn how triad shapes connect, how inversions work, and why the same chord can feel completely different depending on where you play it.

Built for intermediate guitarists

This is for players who are tired of the neck feeling like a set of disconnected boxes.

Triads help you see the chord tones. 6th and 7th chords give you more harmonic color. Progression drills make the shapes feel musical instead of random.

Practice a little every day and the neck starts to open up. Chords become nearby choices, not shapes you have to search for.
