Octaves

Definition

An octave is the interval between one musical pitch and another with half or double its frequency. In music, this concept is essential because it establishes a relationship between notes, creating a sense of harmony and structure. The significance of octaves in melodic composition helps to define scales, chords, and the overall texture of a piece, allowing composers to convey emotion and develop their ideas more effectively.
