Who was the famous classical composer who gave us the tune for “Twinkle, Twinkle Little Star?” If you’re stumped for the answer, you might ask the fourth-grader in your home.The melody for this endearing lullaby is attributed to the Austrian child prodigy Wolfgang Amadeus Mozart (1756-1791), but he apparently adapted the simple sequence of notes from an old French folk song. Mozart and his near-contemporary Franz Josef Haydn, along with Bohemian composer Smetana, were on the playbill Nov. 14 when the Bryan Symphony Orchestra performed at Tennessee Tech University for some 500 Warren County fourth-grade students in an impressive building named for McMinnville native Charles Faulkner Bryan, a composer headed for international fame when died unexpectedly in 1955.
