A trill is a rapid alternation between two adjacent musical notes, typically a half or whole step apart. It's like a musical 'vibration' or 'flutter.' Think of it as a fancy flourish that adds excitement and ornamentation. Trills are often used to emphasize a note or create a sense of drama. They can be short and subtle or long and elaborate. It's like adding a quick, sparkling shimmer to a musical phrase β¨.
