We are well into the season of seasonal concerts at this point. If you are looking for a performance of Handel's Messiah or a Christmas or Holiday Concert, we've dealt with that. Here is what else is happening this week in classical music.

NOT CHRISTMAS:
>> Ironically, possibly the best performance this week also happens to be free, the latest concert in the excellent series at the Library of Congress. On Friday (December 15, 8 p.m.), superstar violinist Joshua Bell will play an all-Schumann program, in various combinations with Paul Neubauer (viola), Steven Isserlis (cello), and Jeremy Denk (pianist and author of a blog). A pre-concert presentation, also free, will be offered at 6:15 p.m. It may be too late to reserve a seat through Ticketmaster, but if you show up early and get a number, you are usually able to take an unclaimed ticket. Go to the First St. entrance of the Jefferson Building.

>> Pianist André Watts will play with the National Symphony Orchestra this week, in the second piano concerto by Saint-Saëns. The program also features Ginastera's Concerto for Strings and an old favorite, Beethoven's Fifth Symphony. As usual, you can hear this concert Thursday (December 14, 7 p.m.), Friday (December 15, 7 p.m.), or Saturday (December 16, 8 p.m.) in the Kennedy Center Concert Hall. Tickets: $20 to $80.

>> The local group Opera Bel Cantanti is offering several performances of Mozart's evergreen opera, The Marriage of Figaro, with multiple casts. I have heard some of the singers and been generally impressed. The run opens this Friday and Saturday (December 15 and 16, 7:30 p.m.), at the Embassy of Austria (3524 International Ct. NW). Six other performances are scheduled for various dates through January 6, at several different venues. As a less expensive opera option, the price is right at $35 (students, $25).

>> The Kennedy Center Chamber Players have a concert on Sunday (December 17, 2 p.m.), in the Kennedy Center Terrace Theater. The program features Beethoven's "Gassenhauer" trio, the Brahms B minor clarinet quintet, and what could be construed as a Christmas work, George Crumb's A Little Suite for Christmas, A.D. 1979 (played by pianist Lambert Orkis). This will not be your regular Christmas Concert. Tickets: $35.

>> Your other options for free concerts this week are the Sunday concerts in the museum series. At the Phillips Collection (December 17, 4 p.m.), pianist Soyeon Lee gives a recital (be aware that you still have to pay the price of admission into the museum). At the National Gallery of Art (where concert and museum admission are both free), Nordic Voices will give a concert of Christmas music from Norway and other countries (December 17, 6:30 p.m.).
