* Unity: Starting and finishing on the same note can create a sense of unity and symmetry in a piece of music. This can be especially effective in shorter pieces, such as preludes or etudes, where there is not as much time to develop and explore different musical ideas.
* Emphasis: Starting and finishing on the same note can also help to emphasize that note and make it more memorable. This can be useful for creating a strong hook or melody that will stay with the listener after the piece is over.
* Resolution: Finally, starting and finishing on the same note can create a sense of resolution and finality. This can be a satisfying way to end a piece of music and leave the listener feeling satisfied and complete.
Here are some examples of musical pieces that start and finish on the same note:
* "Für Elise" by Ludwig van Beethoven
* "Clair de Lune" by Claude Debussy
* "The Entertainer" by Scott Joplin
* "Over the Rainbow" by Harold Arlen
* "What a Wonderful World" by George David Weiss and Bob Thiele
