The BEAM should be page-centered. A BEAM must not be projective, its' predetermined form must act as a conduit to content rather than vice versa. Centering the poem gives it substantiality, while its' imagery lets it float into the stratosphere. It resembles a sonnet with more space, greater airiness.
BEAMs should generally be written in couplets or single lines. A BEAM couplet fulfills the role a beam does in architecture- it builds, structures, supports. Its' central position reinforces the impression of substantiality. Meanwhile, single lines interspersed function as "beams of light"; pure shots into poetic space, flashes of imagery, insight, gist-phrasing, etc. Light-beams illuminate built-beams, built-beams support and buttress light-beams. Together, they posit the BEAM as a kind of light-house or light-structure. A BEAM should blend concrete with ozone, specifics with abstractions, substantiality with ethereality. It is a form built to be seen.
