In music, "enharmonic" refers to two notes that sound the same but are written differently. For example, the note C♯ (C sharp) and D♭ (D flat) are enharmonically equivalent. This means that when played on an instrument, they produce the same pitch, even though their names and notations differ. Enharmonic notes are important in music theory and composition, as they can affect how a piece is interpreted or performed. Musicians often use enharmonic equivalents to simplify notation or to fit a specific key signature, making it easier to read and play music.
