In the hands of one classical and pop music duo, concerts appear to be disasters. The pianist, Richard Hyung-ki Joo, seems to have his right hand amputated by the piano cover. The violinist, Aleksey Igudesman, almost loses his violin bow to a vacuum cleaner. The show goes on anyway — because these mishaps, cuing laughs from their audiences, are all very intentional.

In fact, mistakes are the basis of Igudesman and Joo’s current show, "A Little Nightmare Music," coming Monday to the Long Center for the Performing Arts.

"We’ve found that audiences listen better when something goes wrong," Igudesman said.

Plus, the humorous accidents on stage are part of their mission to make classical music more accessible to young children and high school and college students, typically an age group not likely to be found in a concert hall where Beethoven’s music is playing. So far, their mission seems to be working.

The comedy and theatrics the duo regularly throw into their adaptations of popular songs — a range from the Beatles’ "Ticket to Ride" to a seamless mash-up of Mozart’s "Symphony No. 40 in G minor" with the James Bond theme song — has attracted both young and old audiences and transformed classical music concerts from "resembling funerals, so somber and stiff, rather than celebrations," Igudesman said.

Both he and Joo want their shows to be celebrations of music. By playing such a variety of songs (even a Justin Bieber tune could end up a piano and violin variation at their hands), they hope to show that all types of music can be fun and enjoyable for just about anyone.

"We don’t make a differentiation between classical and non-classical," Joo said. "If you look at the harmonic sequence of ‘I Will Survive,’ one of the songs we perform, you’ll hear the chords are also the chords in ‘Killing Me Softly,’ ‘Final Countdown,’ Tchaikovsky’s 5th Symphony, Vivaldi’s Four Seasons, and so on."

"What we’re trying to say is that all music comes from the same place, and it’s all valid," Igudesman said.
