The practice of architecture takes place in what is aptly called “an architectural practice.” But, in a sense, no architecture takes place there. Unless something outside that practice is built, we merely have plans for architecture, unfulfilled ideas, but nothing that functions or shelters. In this paper, my attempt to show an important connection between improvisation and architecture is about the process of architecture as its execution of a built structure. My idea is to begin with an unheralded example from (...) vernacular architecture, glean from it what I think is improvisational and work with issues I believe are generated from it in order to point out some things about improvisation as well as architecture. That example is the collective of buildings known as the shantytown. The shanty, like the ruin, comes about with “unintentional visual interest” to pervert the phrase of Michael Baxandall, happening as it does without foregrounding concern for architectural beauty or elegance. Philosophical investigations of vernacular architecture are not new, but one where an improvised mode of construction is a serious component of its analysis has largely been passed over. One question I try to answer can put the issue another way: What is the limiting case of improvisation in architecture? (shrink)

I argue for an ontology of jazz according to which it is a tradition of musical performances but no works of art. I proceed by rejecting three alternative proposals: (i) that jazz is a work performance tradition, (ii) that jazz performances are works of art in themselves, and (iii) that jazz recordings are works of art. I also note that the concept of a work of art involved (1) is nonevaluative, so to deny jazz works of art is not to (...) judge it inferior to artistic traditions with works, and (2) is univocal across other musical traditions, so to claim there are works of art in jazz would be to use a different sense of the term than we use when, say, discussing classical music.

In this issue, our contributors demonstrate how art in the city, art “about” the city, art compared to the city, can bring to attention the insidious forces underlying every city’s gleaming, wide-awake veneer.
