The sun rises as the opening theme of Beethoven’s “Eyeglasses” Duo for Viola and Cello, Eb Major, lifts into the morning air. The melody moves from viola to cello and back again, teasing out each instrument’s mellow, sonorous tones – perfect for the day’s beginning. Violin and cello begin a duet in Haydn’s String Duo in D Major, engaging in its classical structure and musical restraint. The mood – and the instruments – shift to Halvorsen’s Passacaglia for Violin and Cello, based on Handel’s original composition; an impassioned duet whose melancholy theme is alternatively pensive and lively, finding resolution in a hopeful, final chord. Two violins offer Halvorsen’s Concert Caprice on Norwegian Melodies, a subtly contained melodic duel that is intriguing and inviting as the violins query and reply in an uplifting offering. This second early morning concert concludes with Serenade for String Trio, a bright and cheerful work for violin, viola, and cello by Hungarian composer Dohnányi. A concert of inspiring and joyful music for an early Friday morning.
