This article is the first major study of cantos de boga (rowing songs) from Colombia's Pacific region. Examining a mix of archival and commercial recordings from a music theoretical and analytical perspective, Tabak finds that many of the songs feature various types of metric asymmetry. She focuses in particular on recordings which contain evenly-spaced beats, but whose measures have irregular lengths ("long-form non-isochronous meters"). Tabak suggests that despite their significant metric irregularities, the cyclic nature of the songs allow listeners to become accustomed to, and even metrically entrain to, the series of irregular measures.
