A pentatonic scale is a musical scale with five notes per octave. It is derived from the major scale by removing the fourth and seventh notes. The term "pentatonic" comes from the Greek words pente, meaning "five," and tonos, meaning "tone." Pentatonic scales are widely used in music from various cultures around the world, including traditional folk music, jazz, blues, and rock. Due to their simple and versatile structure, pentatonic scales are often used to create catchy melodies and improvisations.
