Today’s fifth edition of Tufts Composers’ New Sounds Now series is titled “Self-Similarity: Algo-Rhythmic Composition, Automaticity, and Counting.” Tufts Composers look to composer Tom Johnson, asking: What resembles the thing that just happened? What makes our music move and dance without overthought? Can we count in new ways? Free and open to the public with no tickets required; also viewable via Tufts Music Live Streaming.
