Time Structured Mapping

Article summary

Time Structured Mapping (TSM) is a score based system created and used by the composer Pete M Wyer. It uses the bar-lines found in conventional musical scores to indicate durational periods during which performers, who may include actors, singers, dancers, poets as well as musicians, are given instructions, which may include conventional musical scoring or improvisational guidelines. The system allows large and sometimes disparate groups to improvise together coherently, or to combine improvisation with scored music or with other media. It has been used to get orchestras, including the Orchestra of the Swan (see below), to improvise effectively and in educational projects, to combine student musicians with professionals, such as with Welsh National Opera and to combine other media such as dance and poetry with musical improvisation in a structured form, such as with Miro Dance Theatre, Philadelphia. The flexibility of the system has allowed for the combination of musicians from very different backgrounds, as well as disparate ensembles with players of very different standards. Works generally combine improvisation with conventional scoring and move frequently from one system to the other.…
