also known as Fanfare-Rondeau
You may not have heard of French Baroque composer Jean-Joseph Mouret, but if you ever watched PBS's Masterpiece Theatre, you have heard one of the few compositions to have survived to the present day. It was originally entitled "Fanfare for trumpets, timpani, violins, and oboes" but is now more typically performed by organ, or perhaps piano. It is also a popular choice for wedding music, hence its presence on this site.
