Music to solve by (Puzzle No. 3,264)

Last weekend, Sabers and I sat in on a master class given by Timothy Eddy, cellist with the Orion Quartet.   The first students that he was working with were Alexandra and Brittany Conrad, sisters who are concertmistress and principal bass respectively of the Trowbridge Chamber Orchestra at Settlement Music School (Sabers is principal bass of the intermediate orchestra at Settlement).  The orchestras have their next concert at 3:00 on Saturday, January 27 at the SMS Mary Louise Curtis branch in Philadelphia.

Alexandra and Brittany had prepared a pair of tangos by the Argentine composer Ástor Piazzolla.  Though his family was Italian and he studied in Paris, Piazzola's best compositions are Argentine at heart, but influenced by the jazz musicians he heard in Europe, particularly Gerry Mulligan (who of course was best known for his work with Dave Brubeck).

So while Sabers watched Timothy coach Brittany on the bowing and rhythm of her part, I enjoyed the music and finished solving last week's Patchwork from the WSJ.   Now you can listen to an earlier performance of the same pieces while you do this week's puzzle.

After a one-week sampling of a bar-style puzzle, Hot and Trazom are back with their regular block-style.  Of course there are still a few twists in the clues, so if you need hints, post a comment below.

Degree of difficulty (by standards of this weekly puzzle): moderate to difficult, particularly if you are expecting all clues to be straightforward and self-contained.
