Canadian guitarist Emma Rush plays Babbit by Canadian composer Kendra Harder. This comes via her excellent YouTube Channel. Great playing by Rush and a nice little composition. Many beautiful moments with spacious pacing and that little rhapsodic dance in the middle. The Babbit Square is that 12-tone sudoku-like graph that you might remember from theory class to help you keep track of your tone row. The composer has this to say about the piece at her website where you can also purchase the sheet music:
This is a solo piece for guitar utilizing 12-tone technique. There are moments where the music sounds ethereal, and others where it’s rhythmic and arresting. The piece’s name comes from the 12-tone analytical tool, the Babbit Square (which can actually be a fun afternoon puzzle!)
