Pentatonic refers to a musical scale comprising five notes per octave, derived from a selection of notes within the full diatonic scale. Pentatonic scales are characterized by their simplicity and versatility, often used in various musical traditions around the world, including folk, blues, rock, jazz, and traditional Asian music. These scales are prized for their harmonic neutrality, melodic flexibility, and ease of improvisation, making them popular choices for melodies, solos, and accompaniments in a wide range of musical styles.
