“The array of music in this program is exquisite,” says Corliss Bachman, Pennsylvania Sinfonia Orchestra (PSO) Executive Director.

Pennsylvania Sinfonia Orchestra presents the 2025 summer season’s concluding “Valley Vivaldi Concert No. 3,” 7 p.m. Aug. 24, Wesley Church, Bethlehem.

“Of particular note, the ‘Brandenburg Concerto No. 5’ has a breathtaking harpsichord cadenza and the Telemann work will contrast beautifully with the gem-like sonata for just two intertwining violins by French composer Jean-Marie Leclair,” Bachman says.

Known as the “father of the string quartet,” Franz Josef Haydn (1732-1809) initially termed his quartets divertimentos, each consisting of five movements.

The concert opens with Haydn’s five-movement “String Quartet in B flat major ‘La Chasse’ Op. 1 No. 1.” It was not until his Opus No. 9 that Haydn used the four-movement quartet form, now considered the traditional format.

French composer Jean-Marie Leclair (1697-1764) was known for his blend of French and Italian styles.

Violinists Inna Eyzerovich and Simon Maurer perform Leclair’s three-movement “Sonata for two violins in E minor, Op. 3 No. 5,” published in Paris in 1730.

German composer Georg Philipp Telemann (1681-1767) created the delightful “Concerto for traverso and recorder in E minor” TWV 52:e1, which showcases the contrasting qualities of the traverso (Baroque flute), played by Susan Charlton, and the recorder, played by Rainer Beckmann.

“The two solo instruments of the Telemann concerto are interwoven in delightful and fascinating ways throughout the four movements,” explains Charlton, adding, “The folk character of the Presto suggests influences of the composer’s time spent in the Polish countryside listening to the improvisations of bagpipes and fiddlers.”

Charlton next will perform “Flute Sonata in A minor” Wq 132, H. 562. Consisting of three movements, the work was written in 1737 by Carl Philipp Emanuel Bach (1714-1788), son of Johann Sebastian Bach. Carl Philipp Emanuel Bach was commissioned by King Frederic the Great, an accomplished flutist.

Says Charlton, “This sonata is considered one of the most important works of the flute repertoire, especially before the 20th century.

“The piece displays the great sensitivity and expressiveness of the composer as he moves the baroque style of his father [J.S. Bach] into the classical period and foreshadows elements of romanticism,” Charlton says.

The program continues with Antonio Vivaldi’s (1678-1741) “Concerto for Strings in D Major” RV 124, published in 1729.

The concert concludes with J.S. Bach’s (1685-1750) “Brandenburg Concerto No. 5 in D Major” BWV 1050, featuring Benjamin D’Annibale, harpsichord; Simon Maurer, violin, and Susan Charlton, flute.
