Punch Brothers are reaching out to fans to participate in the making of their next album. The group has put out the request for folks to sing a few lines on the new record "as kind of a meta reference to its theme," says band member Chris Thile. The lines are from a song called "Little Lights," for which Punch Brothers are looking to add "a mighty assembly of your individual Voice Memos and GarageBand sessions" to the studio recording.

Below is a scratch track that Thile recorded as a guide to the song. To record a vocal track of your own, plug headphones into your computer (or whatever device you're listening on) to hear Thile's track as a guide. Remove any exterior noise, like air conditioners and fans. Record a voice memo on your smart phone, GarageBand, etc. (If you're using your phone, you may have to email the file to yourself and then upload it from a computer.)

When recording, say "1 - 2, 1 - 2 - 3" along with Chris Thile's track, skip 4 - 5 - 6, rejoin him on the word "Shine," and sing all the remaining lyrics along with the track. Sing the melody in whatever octave is most comfortable.

Lyrics
Shine little lights of ours
Like Orion's Belt of stars
Connected only from afar
Shine little lights of ours
Like Orion's Belt of stars
Guide us back to where we are
