There was a major discovery of talent Saturday night at the Terrace Theater. Her name is Yun-Jung Chang, one of three brilliant 16-year-old performers in a concert called Young Musicians From Seoul. These gifted musicians were presented under the auspices of the Korean Concert Society of Maryland.

Chopin's mighty Sonata No. 2 in B Flat Minor, Op. 35, is a work that daunts the most mature of pianists. From the opening passages, it was apparent that the audience was in for a performance that had to be one of the finest ever by one so young. Chang displayed finesse, musicianship and sheer dexterity far beyond her years. One hopes to hear from her in the future.

The concert opened with an appropriately dark, somber performance of the Sonata No. 4 in C Major for Cello and Piano by Beethoven, played by Wha-Jin Hong. In this surprisingly (for a work in C) grave piece, Hong played with admirable technique and charm.

Violinist Sung-Won Yun's performance of the Sonata in G Major, "Devil's Trill," by Tartini was incisively played, her complete mastery of the ornaments exciting the audience. Although she did not emerge unscathed from this or the fiendish Polonaise Brilliante in D Major, Op. 4, by Wieniawski, she is also a talent to watch. The violin and cello pieces were accompanied by the sensitive and outstanding Gail Niwa.

The concert closed with a performance of Beethoven's Trio in B Flat Major, Op. 11. Although well played, the piece suffered a bit from Yun's overbearing manner.
