Musical ornamentation refers to the decorative notes added to a melody to enhance its expressiveness and complexity. These embellishments can include trills, turns, and grace notes, which provide a richer sound and can showcase a musician's skill. Ornamentation is often used in various genres, including classical, jazz, and folk music. Historically, ornamentation has played a significant role in the works of composers like Johann Sebastian Bach and Wolfgang Amadeus Mozart. In their compositions, performers are encouraged to interpret and add their own ornaments, allowing for personal expression and creativity. This practice continues to influence modern musicians and their interpretations of traditional pieces.
