Making Midday Music At JHMI Amid hallway conversations and office consultations, the whirring of high-tech medical equipment and the humming of cutting-edge research, a little corner of the Hopkins Medical Institutions gives itself up to a most classical, and unexpected, midday sound: chamber music. Last Tuesday, the JHMI Chamber Music Society performed as the final event of the Office of Cultural Affairs' busy spring schedule, filling Hurd Hall with the sounds of Mozart's Quartet in G, K.387 and Beethoven's Quartet in F Op. 59, No. 1. The Chamber Music Society, which began in 1980 under the direction of Robert Gerle, brings together faculty, students and staff of the Medical Institutions who have an interest in playing in chamber music quartets. Each fall, auditions are held, and, for the past six years, musical director Richard Field--the BSO's principal violist--forms about half a dozen groups. After hours of practice, they perform one or two concerts for their colleagues, usually during working hours. The Medical Institutions schedule a wide range of cultural activities at East Baltimore throughout the year, including conversations, concert series, humanities symposia and seminars, and lectures. In July, the theme of the Office of Cultural Affairs' summer film series will be the 50th anniversary of the bombing of Hiroshima.
