ROCKPORT -- The idea of chamber music as a conversation between individuals is sometimes belied by professional ensembles, which can take on a collective, unified personality. The Miami String Quartet, performing Saturday night as part of the Rockport Chamber Music Festival, demonstrated this single-minded approach, with all its attendant virtues and sins.
The ensemble's sound, keyed by assertive bow attacks that produced near-percussive accents, was well-suited to Alabama-based Charles Norman Mason's "Prelude to a Parlay," premiered earlier this year by the quartet at the novel venue of a Birmingham City Council meeting. The piece, written by Mason during his Rome Prize residency, is a vigorous, rhythmically asymmetrical translation of an old spiritual; the driving, minimalist-inspired repeated-note rhythms played to the group's strengths. The off-balance meters precluded overarching lyricism, and a venture into Victorian harmonies was a too-brief contrast, but the bright, bracing texture held the ear until the slightly abrupt ending.
