Introduction to Power Chords
Power chords are a type of chord commonly used in rock music, known for their strong, full sound. They typically consist of just two notes: the root and the fifth. Power chords are often played in a doubled fashion, with the root note an octave higher to add richness. Their simple structure makes them easy to move along the neck of the guitar, allowing for quick changes in key.
