When the Concert Association of Florida fell apart in 2007, the major concert venues in this area scrambled to put together good classical series to replace the events that had been hosted by the association.

Again this year, the Broward, Arsht and Kravis centers have their own series of classical programs, but there’s another group that is beefing up the offerings this coming season, and they’re doing it with some major names.

That group is the South Florida Symphony, which until very recently was the Key West Symphony Orchestra until it decided to expand its brief beyond Monroe County into the rest of South Florida. For this season’s Master Concert series, the group will welcome two leading young violinists to stages in Key West, Miami, Fort Lauderdale and West Palm Beach.

The first is the fine South Korean-born violinist Chee-Yun, who has had a strong career since emerging in Seoul as an exceptional 8-year-old. She’ll play the Beethoven concerto with the orchestra, led by Sebrina Maria Alfonso, in concerts Oct. 6, 7, and 9; also on the program are the Enigma Variations of Edward Elgar.

Violinist Chee-Yun. The second is the Canadian violinist Lara St. John, who has released excellent albums of Bach solo works as well as a disc of dueling Four Seasons: the Vivaldi set, and four by Argentine tango master Astor Piazzolla. She’ll perform the Mozart Concerto No. 3 (in G, K. 216), a wonderful work, and Sarasate’s Ziegunerweisen on a program with the Beethoven Fourth Symphony on Dec. 1, 2, and 5.

In an e-mail message to me, Alfonso wrote that the South Florida Symphony is aiming to become a cultural force in the area.

“We are committed to becoming leaders in the cultural landscape of South Florida by striving to present high-level classical programming, world-class guest artists, introducing new works and most importantly to become a leader in music education for the area,” she wrote. “We are seeking grants, sponsorships and partnerships that will allow us this privilege.”

This is the second year the orchestra has offered a South Florida-wide series, expanding this year into Palm Beach County. But the Key West ensemble has been presenting similar series for the past 13 years. Alfonso wrote that the caliber of the concerts was such that she felt they “should reach a larger audience, and felt there was a place for the South Florida Symphony in the region.”

The Belfast-born pianist Barry Douglas, a frequent visitor to South Florida in the season, brings the big Brahms Second Concerto (in B-flat, Op. 83) in concerts Jan. 28, 30 and Feb. 1. The concert also includes music by Vaughan Williams (the Tallis Fantasia) and Khachaturian (the suite from Masquerade).

Part-time Pompano Beach resident and Miami native Ellen Taaffe Zwilich will get two of her works performed on the final two concerts of the series: Her Septet for piano trio and string quartet, which had its South Florida debut earlier this year, on concerts featuring the Sima Trio on March, 2, 3 and 7.

Zwilich’s Fifth Symphony is on the final installment in the series (April 29, May 1 and 2), which also welcomes the American pianist Adam Golka for the perennially popular Tchaikovsky First Concerto (in B-flat minor, Op. 23).

This is an interesting lineup, and certainly adds some depth to the upcoming classical season, which will be another very busy one, especially when you consider smaller recitals and chamber music concerts. But we could always use some more symphonic glamour and interest, and this five-part series helps do that.
