Because of its success, The Trumpet Of The Swan had a few adaptations.

Philadelphia Orchestra piece
In 1972, a piece by composer Benjamin Lees based on The Trumpet of the Swan was performed by the Philadelphia Orchestra (an orchestra with which Louis is mentioned as giving a guest performance).
An animated film of the book was made in 2001 by Rich Animation Studios, released by Nest Family Entertainment and distributed by Sony Pictures Entertainment under the TriStar Pictures flagship. It was released theatrically in the United States on limited release. It was not well received by critics. Many stated that the animation was choppy, the characters were dull, the voice casting did not match, the songs were unmemorable, the character designs were ugly and the jokes were stupid. But the most common criticism of the film version was that its script was unfaithful to the original story. This disappointed many fans of the book. According to Rotten Tomatoes, it scored 13% rotten on the tomato-meter.
A "novel symphony for actors and orchestra" was adapted from the book in 2011 by Marsha Norman with music composed and conducted by Jason Robert Brown. The production starred John Lithgow, Kathy Bates, Jesse Tyler Ferguson, Mandy Moore, James Naughton, and Martin Short. The production has been published on CD and by direct download.
