Slahal is an Indigenous team-oriented gambling game that involves skill, luck, strategy, supernatural assistance, and a specific song genre. As part of a long tradition of Indigenous gaming in the Pacific Northwest, it has become a popular form of intertribal competition throughout the region.
Song is integral to slahal; the songs, with their catchy melodies and driving frame drum accompaniment, are sung loudly and enthusiastically by the hiding team. Group singing provides opportunities for individual expression through variation of form and rhythmic accompaniment, as well as polyphony and antiphonal singing.
This according to Slahal: More than a game with a song by James Everett Cunningham, a dissertation accepted by the University of Washington, Seattle, in 1998 (RILM Abstracts 1999-22855).
Below, an example from British Columbia.
Scrabble™-to-MIDI is a computer-emulated two-dimensional board game that generates MIDI music as the game is played.
The plug-in translator and its configuration parameters comprise a composition. Improvisation consists of playing a unique game and of making ongoing adjustments to mapping parameters during play.
Statistical distributions of letters and words provide a basis for mapping structures from word lists to notes, chords, and phrases. While pseudo-random tile selection provides a stochastic aspect to the instrument, players use knowledge of vocabulary to impose structure on this sequence of pseudo-random selections, and a conductor uses mapping parameters to variegate this structure in up to 16 instrument voices.
This according to “Algorithmic musical improvisation from 2D board games” by Dale E. Parson, an essay included in ICMC 2010: Research, education, discovery (San Francisco: International Computer Music Association, 2010). Above, a demonstration of Scrabble™-to-MIDI.
