"Feels So Good" is the title of an instrumental composition by the American flugelhorn player Chuck Mangione. It was written and produced by Mangione, and is the title track from his 1977 album.

The flugelhorn, also spelled fluegelhorn, flugel horn, or flügelhorn, is a brass instrument that resembles the trumpet and cornet but has a wider, more conical bore. Like trumpets and cornets, most flugelhorns are pitched in B♭, though some are in C. It is a type of valved bugle, developed in Germany in the early 19th century from a traditional English valveless bugle. The first version of a valved bugle was sold by Heinrich Stölzel in Berlin in 1828. The valved bugle provided Adolphe Sax with the inspiration for his B♭ soprano (contralto) saxhorns, on which the modern-day flugelhorn is modelled.
