Haruka and Ayako Watanabe have been an important part of the St. Louis musical scene for over four decades. He’s a member of the first violin section of the St. Louis Symphony Orchestra; she was the regular second harp. They raised two musical sons: Hideki, an organist, and Kaoru, a flutist.

Kaoru, who spent nearly a decade as a member of the Japanese drum ensemble Kodo, will join his parents as part of Trio Watanabe. They’ll perform Haruka’s own original compositions, from their CD “Song of Shinobue.” (The title refers to the Japanese transverse flute that Kaoru plays.) They’ll be joined by Japanese dancer Mitsue Wakabayashi for the performance.

Trio Watanabe performs “Song of Shinobue” at the Palm House in Tower Grove Park, 4526 Magnolia, Thurs., May 1 at 7 p.m. Admission $10 at the door.
