The Jonas Brothers are experimenting with a new kind of musical harmony this holiday season... but instead of using their voices, they're using bells!

That's because JoBros have teamed up with the Salvation Army to create this brand-new PSA about how you can give needy families a meaningful Christmas this year.

Here's what they have to say: We all know one of the typical scenes during Christmas-time (besides the tree and presents, of course) is seeing that good ol' red kettle on the street with someone ringing a bell and asking for donations. Now the Brothers are asking you to be a part of one of the most longstanding charity traditions by volunteering to ring that bell yourself!

Ever since 1891, people have been giving their time to ring the bell and support the red kettle which provides for the poverty-stricken. Today, the Salvation Army provides for more than four-and-a-half million people during the holiday season. Donations provide Christmas dinners, clothing, and toys to needy families, seniors and the homeless to keep the holiday spirit alive.

So what do you say? Will you join the JoBros and help ring bells this Christmas? If so, here's how you can get started!
