The significance of the mass media in everyday musical life can scarcely be exaggerated. Music is nowadays, to a large degree, heard in technologically communicated form, i.e. as ‘transmitted music’ (Übertragungsmusik), not live (see especially Silbermann 1954, Eberhard 1962, Jungk 1971, Goslich 1971, Bornoff 1972, Blaukopf, Goslich and Scheib 1973, Schmidt 1975, Rösing 1978a, Brinkmann 1980, Hosokawa 1981). It can be assumed that young people and adults in the Federal Republic of Germany (FRG) consume, on average, a good three hours' worth of music a day, on radio, cassette recorder, television or records. The fact that music, by means of the technological transmission-chain, is available at all times and can be replayed at will, independent of the here-and-now of live performance, has far-reaching consequences for the listening behaviour, listening expectations, musical preferences and musical understanding of every individual. Two of these aspects, listening behaviour and musical preferences, will be examined in detail in what follows.
