Music Theory Basics

Understanding music theory helps you communicate with other musicians and understand why music works.

Notes and Intervals

  • Half Step (Semitone): One fret on the guitar
  • Whole Step (Tone): Two frets on the guitar
  • Octave: Same note, 12 frets higher

Chord Construction

Chords are built from scales. A major chord uses the 1st, 3rd, and 5th notes of the major scale.

Example: C major = C (1st) + E (3rd) + G (5th)
