Timothy Day, former principal flutist of the Baltimore Symphony Orchestra and now playing and teaching in San Francisco, returns to Baltimore at 3:30 p.m. Sunday for a Pro Musica Rara program of music from the Court of Frederick II (The Great) of Prussia.
The six chamber players in the Baltimore Museum of Art concert will play sonatas and other pieces by composers well known in the "Berlin School" of musicians employed by Frederick, according to Shirley Mathews, harpsichordist and artistic director.
"The German version of Rococo is . . . elegant and, to some, fussy music inspired by French models," Mathews said. "We admire the music for its declamatory and expressive qualities. In chamber music for the flute with other instruments, it is unsurpassed."
A founding member of Pro Musica Rara, Day will play the transverse flute -- the instrument Frederick played. He joins Mathews, violinist Craig Richmond, violist Sharon Pineo Myer, bassoonist Phillip Kolker, Elizabeth Ferrell playing the viola da gamba.
Composers of the works are Johann Friedrich Fasch (1688-1758), Johann Gottlieb Graun (1702-1771), Carl Philip Emanuel Bach (1714-1788), Claude-Benigne Balbastre (1727-1729) and Johann Sebastian Bach (1685-1750). Tickets are $12, $9 for seniors and museum members and $5 for full-time students. Call 889-4920.
Johannes Brahms' "A German Requiem" will be offered in a free Sunday concert, at 3 p.m. in Turner Auditorium of the Johns Hopkins Hospital, E. Monument Street at Rutland Avenue. The Requiem will be sung by the Choral Society and Chamber Orchestra of the Hopkins Medical Institutions.

Cimino, choirmaster, will sing the pop cantata "Holy Moses" by Chris Hazell, at Calvary Baptist Church, 120 W. Pennsylvania Ave., in Towson. The cantata is described as a lively upbeat story of the life of Moses. The program's second half is devoted to sacred and secular favorites. The concert is free; donations will be taken.
The choir of 20 boys and 10 men is in its fourth season and plans 12 public and private concerts this year. The choir rehearses twice a week, joined once by the men. Rehearsals are at St. Andrew's Episcopal Church, 6515 Loch Raven Blvd. A week-long summer choir camp is held at Gettysburg College.

An unusual concert that began with a citizen's fund drive will feature a new harpsichord built by master craftsman David Sutherland at 8:30 p.m. Friday at the Montgomery Recital Hall, St. Mary's College, St. Mary's City.
The free harpsichord dedication concert by the Maryland Bach Aria will feature music by Bach, Handel and Telemann. The college's Arts Alliance set up a "Notables Club," with $200 memberships, to buy the $12,200, 61-note keyboard instrument. Citizens gave in a one-year drive. Patti Runco was steering committee chair.
Sutherland, of Ann Arbor, Mich., modeled the harpsichord after an 18th century Italian design by Bartolomeo Cristoferi.
The college said the instrument "represents the purist rendition of the harpsichord proper" and is "elaborately decorated in gold leaf and a Roman mosaic design. Its lively sound derives from its simplicity, clarity and shortness of speech, making it perfect for accompaniment."
Other concerts this weekend include Bill Staines, New England songwriter, singing his original folk songs at 8 p.m. Friday at the Walters Art Gallery. Tickets for the Baltimore Folk Music Society show by Staines, of the Boston-Cambridge folk scene, are $10 and $8 for Walters and society members.
