The sound (s) of Bernstein

Technically, Leonard Bernstein’s 100th birthday isn’t until Aug. 25. But the party started on that date last year and continues around the world through his centennial date.

The celebrations — more than 2,000 of them, on six continents — kicked off last September at the Kennedy Center in Washington, D.C. (A most appropriate venue, considering Bernstein’s “Mass” premiered during the Kennedy Center’s 1971 debut.)

Southern Nevada joins the Lenny celebration this spring, bringing multiple opportunities to experience Bernstein’s music, including:

■ Opera Las Vegas — “Bravo, Bernstein!” salutes the composer’s legacy at a concert and Champagne reception featuring some of Lenny’s greatest hits, from Broadway (“West Side Story,” “On the Town,” “Candide”) to opera (“Trouble in Tahiti”) and beyond (the aforementioned “Mass”); 3 p.m. March 25, Cabaret Jazz at The Smith Center. ($100; thesmithcenter.com)

■ UNLV Wind Orchestra — “Bernstein, Bernstein and Associates” spotlights the 65-member orchestra performing “Symphonic Dances from ‘West Side Story,’ ” the stirring “Candide” finale “Make Our Garden Grow” and “Slava!” — which Bernstein wrote for cellist Mstislav Leopoldovich “Slava” Rostropovich. (The “associate” in this concert is Bernard Herrmann, acclaimed for his Alfred Hitchcock movie scores; he’s represented by “The Death Hunt” from the 1952 film noir classic “On Dangerous Ground”); 7:30 p.m. April 19, Artemus Ham Hall at UNLV. ($10; unlv.edu/pac)

■ Henderson Symphony Orchestra — It’s the best of all possible worlds as the Henderson Symphony Orchestra stages the winning “Candide,” based on Voltaire’s 1759 novel, with lyrics by (among others) Richard Wilbur, Dorothy Parker, Lillian Hellman, Stephen Sondheim and Bernstein himself; 8 p.m. May 11 at the Henderson Pavilion. (Free; hendersonsymphony.org)

■ Las Vegas Philharmonic — The orchestra’s season finale (which also features Beethoven’s “Emperor” Piano Concerto and Prokofiev’s Symphony No. 5) kicks off with Bernstein’s lively “Fancy Free: Three Dance Variations,” from the 1944 ballet (choreographed by Jerome Robbins) that inspired the musical “On the Town”; 7:30 p.m. May 19 in Reynolds Hall at The Smith Center. ($30-$109; lvphil.org)
