👉 Riffs are a type of musical structure that is often used in rock, blues, and other forms of music. They consist of two or more notes played together with different pitches (e.g., C major, D major) to create a melody. Riffs can be simple or complex, and they can be written down as chords or melodies. In this context, "riff" refers to the way in which the guitar strings are struck to produce a particular sound or feel when played together.
