Guest artist Rainer Beckmann performs on the recorder for the final Valley Vivaldi 2018 summer concert presented by the Pennsylvania Sinfonia Orchestra at 7 p.m. Aug.19, Wesley Church, 2540 Center St., Bethlehem.

Baroque composers Antonio Vivaldi and J.S. Bach figure prominently on the program, as well as Arcangelo Corelli, Georg Telemann and Marin Marais. The composers are from the mid- to late-17th century through the 18th century.

Beckmann and the PSO perform Vivaldi’s “Concerto in G for Recorder and Strings,” RV 443, and Telemann’s “Trio Sonata in D,” TWV 42:d10. The sonata is scored for recorder, violin, and continuo, which for this performance will be cello and harpsichord.

Beckmann, a native of Germany, performs on the recorder with early music ensembles in the Philadelphia region. He is a founding member of La Bernardinia Baroque Ensemble, a member of Vox Renaissance Consort, and director of the Greater Philadelphia Area Recorder Academy.

Cheryl Bishkoff, Sinfonia principal oboist, is soloist for Bach’s “Oboe d’Amore Concerto in A,” BWV 1055.

Bishkoff is principal oboe of the Rhode Island Philharmonic, plays with the Boston Ballet, and teaches at Vassar College, Brown University and Wheaton College.

An intriguing one-movement work by French composer Marais, “Sonnerie de Ste. Geneviève du Mont de Paris,” emulates the rolling waves of sound created in a church bell tower. Bold, rich sonorities are achieved with violin, cello and harpsichord.

The program includes Italian violinist and composer Corelli’s “Trio Sonata in D, Op. 3 No. 2.

The soloists are joined by Mary Ogletree, Rebecca Brown and Simon Maurer, violins; Agnès Maurer, viola; Elizabeth Mendoza, cello; Nancy Merriam, bass; and Allan Birney, harpsichord.

A reception follows the concert.
