Question: what are major guitar chords?
Answer: The major chord contains the 1st, 3rd, and 5th notes of a major scale. For example, below is a C major scale. The notes of a C major chord are the 1st (the root note), 3rd, and 5th notes, which are C (the root note), E and G. Notice that the octave (the 8th note) is also part of the chord.
