State triads and chord construction precisely and explain why it matters in 2-3 sentences.

# Triads and Chord Construction **A triad** is a three-note chord built by stacking two intervals of a third above a root note, creating root-3rd-5th structures. **The four triad types:** - **Major**: root + major 3rd + perfect 5th (e.g., C-E-G) - **Minor**: root + minor 3rd + perfect 5th (e.g., C-E♭-G) - **Diminished**: root + minor 3rd + diminished 5th (e.g., C-E♭-G♭) - **Augmented**: root + major 3rd + augmented 5th (e.g., C-E-G♯) ## Why It Matters Understanding triads is fundamental because they form the harmonic foundation of Western music—nearly all complex chords are extensions or alterations of these basic structures. This knowledge allows musicians to instantly recognize chord quality by ear, construct harmonies in any key, and understand how tension and resolution work in progressions.
