Slip back into the 18th century with sonatas by Bach, Vivaldi and other famous composers on Sunday with ISU’s Basically Baroque.

Basically Baroque, the ISU Department of Music duo of Kevin Schilling and Lynn Zeigler, along with two guests, will be giving a concert titled All Baroque.

All Baroque will present the most common form of chamber music from the baroque era, 1600-1750, the trio sonata.

Schilling, associate professor of music, said the name, trio sonata, misleads some people because it actually involves four people. This is “because two people are playing the same part.”

The “trio” consists of two melody instruments plus the “basso continue,” which is actually two instruments, in this case the cello and harpsichord, playing the bass line and the harmony.

Schilling will be playing the baroque oboe, a copy of a British instrument made about 1700.

Zeigler, also an associate professor in music, will play a harpsichord based on a French instrument from the same period.

Schilling and Zeigler will be joined by baroque flutist, Rebecca Stuhr from Grinnell and cellist Mary Pshonik.

Pshonik, a senior in music performance, is principal cellist with the ISU Symphony, a member of the Des Moines Symphony and past principal cellist of the Central Iowa Symphony.

“This is the second program we’ve put together,” Schilling said about the quartet. The first one was performed in November at Iowa State and in February at Grinnell.

Because the baroque instruments are not as strong and powerful as modern instruments, Schilling said, the audience can expect to hear “expression through lightness and delicacy” as well as “nuances,” which are slight variations in tone.

“There will be much more emphasis on small shading and expression, such as more subtle articulation,” he said.

“We hope a lot of people come to the concert and listen to the expression,” Schilling said. Compared to modern performance, “one may have to be sensitive in a little different way.”

All Baroque will begin at 7:30 p.m. in the Music Hall Recital Hall.

The concert is free and open to the public.
