But other orchestras are also trying to incorporate technology.
The Philadelphia Orchestra is among a handful that has developed its own mobile application to let audience members follow along with program notes, like translations of vocal parts, in real time from their personal devices.
The Los Angeles Philharmonic rolled out "Van Beethoven" a customised van that gave residents lasrt autumn a chance to enjoy a performance of Beethoven's fifth Symphony using virtual reality headsets.
And the Sacramento Philharmonic and Opera,Vorginia Symphony Orchestra are among those offering " tweet seats", specially designated sections where concertgoer are encouraged to interact on Twitter with a concert official as they gave running commentary during select performances.
Jesse Rosen, president and CEO of the League of American Orchestras, an aproximately 800- member group based in New York, says orchestras are trying to appeal to a new generation's chaneing expectations for the concert experience.
"It's about enhancing the visual experience of listening to a symphony orchestrahe says. "It's also about making the experience more intimate and creating a more visible contact between the performer and the audiences really seem to value" The Boston orchestra is rolling out the IPads as part of a broader effort draw patrons, particularly younger ones, to their underperforming Friday concerts.
During "Casual Fridays",symphony tickets are being offered at significantly lower prices, ranging from US$25-45 (900-1,600 bath) down from as much as $145, patrons and being encouraged to dress casually, and the hall is hosting pre- and post-concert receptions with live music, snacks and a cash bar.
The first performance was Jan 15; two others have so far been scheduled for Fed 12 and March 18.
Efforts to appeal to new audiences are not without opposition from symphony traditionalists.
There's been resistance all along to screens in concert halls," observes Rosen, of the League of American Orchestras.
Jeremy Rothman, vice-president for artistic planning at the Philadelphia Orchestra, save concerns over its LiveNote app, which debuted this season at select concerts,have diminished as concertgoers and musicians alike saw the technology in action.
The app, he says, has helped some patrons become more informed and therefore more engaged in the performance while the app's design - greyscale text on a black backgrond - minimises the impact on others.
