1. Trio Allegro--Jensen 2. Pyramids--Jensen 3. Slightly Baroque--Jensen 4. In the Hall of the Mountain King--Grieg/Jensen These four unaccompanied trios were written or arranged with the medium level of High School in Mind. "Slighty Baroque" might be a bit more advanced. Ranges have been kept within reasonable limits. Works should be interesting as there a variety of styles presented in these four works.
