Transparency, for harp and tape, was produced at the Institute of Sonology in the Netherlands and premièred in Tokyo in 1984. The electronic part was made by means of a computer programme, which was a rare procedure at the time, still in its infancy – that is why it is historically important, as a pioneering work of computer music. Also, the electronic part serves as a timbral extension of the acoustic instrument, which means that the relationship between the harp and tape is, in a sense, transparent.
