National income per head is an indicator of the standard of living. However, this measure is necessarily a rough one. For instance, it cannot take into account new and better products such as television, man-made fibres, faster flight, long-playing records or the lowly plastic bucket; nor does it indicate changes in the distribution of income between rich-and-poor; nor in the length of the working week. Data of national income per head may also conceal important changes in the "quality of life" as for example, in out physical environment.

Benjamin Britten (1913-76) did as much as anyone to establish English music on the forefront of the international stage. Much of his music seems to have an immediate appeal to large audiences and definitely his many stage works earned him a quite exceptional prestige both at home and abroad. Peter Grimes (1945), Bill Budd (1951). Gloriana (1953), and A Midsummer Night's Dream (1960) all show his mastery of stage technique and the first two are also moving human documents. On a smaller scale he has achieved as much with his chamber operas as such as The Rape of Lucretia (1946), Albert Herring (1947), The Turn of the Screw (1954). His operatic output was crowned by Death in Venice (1973). If he had written nothing else, these dramatic works would have marked him out as a composer of outstanding imaginative gifts.

A. is related to the piece of music in drama
