One of the most basic structures in music are chords. Chords create harmonies with various tones and are typically composed ones, thirds, and fifths. There are four basic chords that this lesson will discuss. Major chords, minor chords, diminished and power chords are what we shall discuss. The first three have a third while the fourth: power chords are just first and fifths with no third interval. Major chords use the intervals 1, 3, and 5. Minor Chords use the 1, b3 and 5 intervals. Diminished Chords utilize 1, b3, and 5 intervals. When playing the modes with chords, one would use major chords for Ionian, Lydian and Mixolydian; while using minor chords for Dorian, Phrygian, and Aeolian, while playing a diminished chord for Locrian. By not having a third interval, power chords are used for a lot of rock songs and can be an interesting choice when composing something to listen to.
