Here are only pieces in which what you see has a direct, perceivable connection to what you hear and vice versa. They are by such colleagues as Toshi Ichiyangi, Gyorgy Ligeti, Yannis Xenakis and Steve Reich. All depart from conventional musical symbols, and even viewers who are not performers can decipher many of the directions. Exhibitions including musical scores usually have presented the notations without an aural counterpart. A compact disc of the works has been produced for purchase, opening the way for visitors to have a more private recollection of the gallery event.
Chance is a major component, as it was in several of the scores.
But here music often is generated apart from performers, by such means as water, a mechanical-toy orchestra and solar panels. There also are pieces that have to do with poetry, happenings, even relationships between sound and architecture.
