Four centuries' worth of chamber music can be sampled this week:
* The most recent repertoire will be heard today, as members of the Baltimore Symphony Orchestra present another of their diverse "Chamber Music by Candlelight" programs. Bartok's String Quartet No. 1 and Poulenc's Sextet for Piano and Winds will be featured, along with pieces by Mendelssohn and C.P.E. Bach. Performers include flutist Elizabeth Rowe, oboist Jane Marvine, clarinetist William Jenken, cellist Dariusz Skoraczewski and the Atlantic String Quartet.
The concert begins at 7:30 p.m. in the acoustically superb Second Presbyterian Church, 4200 St. Paul St. Admission is free; donations welcomed. For information, call 410-719-7357.
* The 17th century will be the primary focus of the next "Music in the Great Hall" event, performed by viola da gamba player Anne Marie Morgan, violinist Emlyn Ngai and theorbo player William Simms. This program contains works by Purcell and some much less frequently encountered baroque composers, among them Johann Heinrich Schmelzer and John Jenkins. Performances are at 8 p.m. Friday and 3 p.m. Jan. 13 at Towson Unitarian Universalist Church, 1710 Dulaney Valley Road. Tickets cost $15, $6 for students. Call 410-813-4255.
