In this guitar masterclass, Lyle Brewer teaches minor triads across all string sets on the guitar. He begins by reviewing major triads and explains that to get minor triads, you simply flatten the third of each chord. Lyle then demonstrates minor triads on each string set, providing examples and connecting the shapes to open chords that students may already know.

Lyle emphasizes finding connections between chord shapes in different areas of the fretboard. He also discusses different approaches to practicing triads, whether focusing on individual string sets or combining positions. Michael asks how to play certain voicings without muddying the sound, and Lyle provides suggestions for right-hand technique.

Later, Lyle demonstrates connecting the triads by playing the Carlos Santana song "Oye Como Va." He voices the chords to emphasize voice leading between A minor and D major. Lyle explains how understanding voice leading can inspire musical ideas when improvising. The masterclass ends with Lyle taking additional questions and encouraging students to apply their new triad knowledge in musical contexts.
