[00:00.00]In order to show you how a big symphony orchestra is put together,[00:05.32]Benjamin Britten has written a big piece of music,[00:08.80]which is made up of smaller pieces[00:10.58]that show you all the separate parts of the orchestra.[00:13.52]These smaller pieces are called variations,[00:16.47]which means different ways of playing the same tune.[00:19.61]First of all, he lets us hear the tune or the theme,[00:23.35]which is a beautiful melody[00:24.54]by the much older British composer Henry Purcell.[00:28.02]Here is Purcell's theme played by the whole orchestra together.[00:31.91]MUSIC[01:00.67]Now, Mr. Britten lets you hear the four different families of the orchestra[01:04.49]playing the same Purcell theme in different ways.[01:07.64]First, we hear the woodwind family.[01:09.52]The flutes, the oboes, the clarinets and the bassoons.[01:13.38]MUSIC[01:35.46]Here comes the brass family.[01:37.17]The trumpets, the horns, the trombones and the tubas.[01:43.07]MUSIC[02:02.61]Now, Mr. Britten arranges the Purcell theme for the string family.[02:06.16]The violins, the violas, the cellos and the double basses.[02:10.60]And of course, the harp.[02:13.94]MUSIC[02:34.53]And finally the percussion family,[02:36.42]all those drums and gongs and things you hit.[02:38.96]MUSIC[02:42.41]After this, you will hear the theme by Purcell played once more[02:45.53]in its original form by all four families together.[02:48.94]That is, the whole orchestra.[02:57.34]MUSIC
