The performance will begin at 8 p.m. Jan. 29 in Karl Umrath Lounge. Following the concert, the audience is invited to a reception of Viennese pastries and coffee sponsored by the Austrian Society of St. Louis.

The Kingsbury Ensemble specializes in music of the Baroque and classical periods, employing historically accurate practices and instruments and performing in acoustically appropriate settings.

Maryse Carlin, instructor in the Department of Music, directs the ensemble, which frequently draws performers from across the United States.

The fortepiano, the main keyboard instrument of the classical era, bridges the Baroque harpsichord and the modern piano.

Seth Carlin — who has recorded works of Mozart and Haydn and recently made several appearances as fortepianist with Nicholas McGegan's Philharmonia Baroque in California — will play a replica of an instrument made in Vienna in 1796 by the maker J.J. Könnicke. The copy was built in Boston in 1982 by Robert Smith.

Carlin will be joined by violinist Patricia Ahern, a member of Tafelmusik, the acclaimed Toronto-based early music ensemble, and Chilean cellist Pablo Mahave-Veglia, who teaches at Grand Valley State University.

The program will open with Haydn's "Trio in D Major, Hob. XV/24" for violin, cello and fortepiano, followed by Carlin and Mahave-Veglia performing Beethoven's "Cello Sonata in G Minor, Op. 5, No. 2."

Ahern will then join Carlin for Mozart's "Violin Sonata in G Major, K. 396." The program will conclude with Mozart's "Concerto No. 12 in A Major, K. 414" for fortepiano and a small ensemble of strings.

Tickets are $15 for the general public; $10 for seniors and WUSTL faculty and staff; and $5 for students.

Tickets are available through the Edison Theatre Box Office, 935-6543, and at the door.
