"A Line Alone" is a monody for solo resonator guitar. "Monody" is the technical term for music that proceeds one-note-at-a-time. For this video I used a baritone El Trovador model, made by the National Reso-phonic guitar company of San Luis Obispo, California. The strings' sounds are amplified mechanically by the instrument's single aluminum cone, which sits directly beneath the top's shiny cover plate. The strings' sounds are not only reinforced by the cone, but they are done so with sufficient loudness as to also active the natural harmonics of the other strings, giving the guitar an effect of having a built reverb, albeit without the use any electricity! This is one of my favorite characteristics of this instrument, and a characteristic that prompted me to compose a monody for the instrument. Although any comparison between this piece and monks, say, singing Gregorian chant in a cathedral is far-fetched, at least as regards the overall effect of the piece, the basic idea here is the same: to make a one-line piece wherein harmonies can be built up by putting a line of single notes into a resonant space, in this case an aptly named resonator guitar.
