ABSTRACT
From the mid-1960s on, pop musicians succeeded in loosening some of the constrictions of the music industry. Willing to do their own thing, they eagerly used their newly-won freedom to extend the expressive powers of their trade. The dorian mode and it associated keys, which glue the tracks of The Dark Side of the Moon to one another, is by itself pre-modern. Over time, it has been preserved not only in folk music, but also in religious music. The tone trap, in turn, actualizes past or future experiences. Of course, as music history shows, these harmonic contraptions were not new at the time Pink Floyd applied them to their songs on The Dark Side of the Moon. However, by combining them so closely in the compact format of their composition, the Floyd turned it into a unique journey through time, leading from childhood misery to adult madness.
