? DAY OF CARTER (Saturday) The New York Philharmonic, in its full form, has contributed precious little to the Elliott Carter centenary celebrations that have occupied much of the musical world. But the orchestra’s musicians are convening on Saturday for a program of Mr. Carter’s chamber works, including the Clarinet Quintet, “Figment III” for solo bass, and the premiere of his “Poems of Louis Zukofsky,” with Lucy Shelton as the soprano soloist. The program opens with a filmed interview with Mr. Carter and the composer Steven Stucky, and ends with a discussion between Mr. Carter and Matias Tarnopolsky. At 2 p.m.. Stanley H. Kaplan Penthouse, 165 West 65th Street, Lincoln Center, (212) 721-6500, nyphil.org; $25; $12 for students and 65+. (Kozinn)
? MAKING MUSIC: ELLIOTT CARTER (Friday) Elliott Carter’s 100th birthday is now behind us — it was on Thursday — but composers’ birthdays are typically celebrated for at least a year and a half these days, so the party rolls on. In this installment of Carnegie Hall’s “Making Music” series, a solid new-music chamber ensemble — with the cellist Fred Sherry, the flutist Tara Helen O’Connor, the clarinetist Charles Neidich and the violinist Rolf Schulte among the players — gives the world premiere of “Duetting” and the New York premiere of “Mosaic.” Also on the program are “Canon for 4,” “Enchanted Preludes,” “Gra,” the Duo for Violin and Piano, “Con Leggerezza Penosa” and “Esprit Rude/Esprit Doux.” Included as well are film interludes by Frank Scheffer. At 7:30 p.m., Zankel Hall, Carnegie Hall, (212) 247-7800, carnegiehall.org; $30. (Kozinn)
