The West Medford Community Center presents “A Life in Music Lost & Found: My Journey as a Musician With Hearing Loss,” a “talk and play” presentation with Betty Hauck, violin and viola. For 50 years, Hauck enjoyed a rich and rewarding career as a professional violist — including performing for the Kennedys at the White House, in a string quartet with Yo Yo Ma, and solo with the Boston Pops — until the day she realized that she had to retire because of progressive hearing loss. For three years, she completely turned her back on music. In this presentation, she tells how various twists and turns led her back into sharing the joy of music while educating and advocating for those with hearing loss. Her talk is punctuated by short musical selections on both violin and viola. A question-and-answer period will follow her approximately one-hour program.
