Here’s a tasteful way to deal with rude concertgoers interrupting performances with their errant cellphone ringtones: Slovakian musician Lukáš Kmit, jolted by the dulcet tones of a Nokia phone in the midst of his performance, played the ringtone back to the audience on his viola.

If only the New York Philharmonic could have done the same thing earlier this month, instead of stopping its performance for an iPhone’s incessant rendition of “Marimba.” Still, a cell phone etiquette reminder: Don’t be that guy (or girl). Your phone should be powered down as soon as the house lights are dimmed.

Update: An earlier headline misidentified the instrument. It has been corrected.
