Pennsylvania Sinfonia Orchestra (PSO) presents “Graceful Gestures,” 7:30 p.m. Nov. 20, Christ Lutheran Church, 1245 W. Hamilton St., Allentown.

It’s a return to in-person concerts for the PSO after the coronavirus (COVID-19) pandemic shutdown. The venue requires attendees wear face masks.

The concert program features two pieces for harp with strings, which will be performed by guest harpist Frances Duffy and the orchestra, conducted by Pennsylvania Sinfonia Orchestra Music Director Allan Birney.

Centerpiece of the program is “Danse Sacrée et Danse Profane for Harp and Strings,” a 1904 composition by Claude Debussy.

The concert includes “Aria in Classic Style for Harp and Strings” by Marcel Grandjany. It’s dedicated by the PSO musicians and board of directors to the memory of long-time PSO board member Dr. Edward J. P. Ciecko, who died in July.

The concert opens with “Concerto Grosso in D, Op. 6 No. 5” by George Frideric Handel and concludes with the six-movement “Suite for Strings” by Leos Janacek.

Duffy has more than 20 years’ experience as harpist, including with the New York Philharmonic; the Broadway shows, “Wicked” and “The Producers”; in recital at Carnegie Hall, and with music superstars Johnny Mathis and the Moody Blues.

Duffy, a member of the Linaria Ensemble, appeared as soloist with the PSO in 2014 and 2013.
