👉 Semioscillation is a phenomenon observed in musical scales that occurs when two notes are played simultaneously, creating a wave-like oscillation. This phenomenon is most commonly seen in the pentatonic scale, where the first and fifth notes of each major third play back to each other. In this case, semioscillation can be defined as the repeated note-to-note interaction between two different notes in a musical scale, which can create an interesting and unique sound effect.
