0:00:13 > 0:00:16MUSIC: Trumpet Concerto in E Flat by Joseph Haydn
0:00:19 > 0:00:22Those composers are just like superstar strikers
0:00:22 > 0:00:24shooting for goal.
0:00:24 > 0:00:26They just know how to write a piece of music
0:00:26 > 0:00:29that's going to hit the back of the net every time.
0:00:29 > 0:00:30CONCERTO CONTINUES
0:00:36 > 0:00:39Joseph Haydn, 18th-century Austrian composer.
0:00:39 > 0:00:42He used to have to write melodies for the orchestra
0:00:42 > 0:00:45he managed that were memorable and bang on target.
0:00:45 > 0:00:49Otherwise, he'd get the boot from the prince who employed him.
0:00:49 > 0:00:52Luckily, Haydn had an ear for a catchy tune,
0:00:52 > 0:00:55the kind that his boss could hum to for weeks and weeks
0:00:55 > 0:00:57while wallowing in his posh bath.
0:00:59 > 0:01:00And his record speaks for itself.
0:01:05 > 0:01:06Take this concerto,
0:01:06 > 0:01:09where the trumpeter takes the role of superstar striker
0:01:09 > 0:01:12and plays a real crowd-pleaser of a melody all of their own.
0:01:12 > 0:01:14CONCERTO CONTINUES
0:01:18 > 0:01:20Haydn knows that's not enough,
0:01:20 > 0:01:23so he opts for a rondo formation for this piece.
0:01:23 > 0:01:27That's a musical structure where the main melody keeps returning -
0:01:27 > 0:01:30like a chorus, but alternates with different musical interludes,
0:01:30 > 0:01:34so the rest of the players aren't sitting about doing nothing.
0:01:34 > 0:01:37They are providing the interludes, picking up the tempo
0:01:37 > 0:01:40and creating variety - but, in the end, always passing the ball back
0:01:40 > 0:01:41to the star striker,
0:01:41 > 0:01:44who only has eyes for goal.
