Ukulele-playing Angelenos, this is your moment to shine. The Music Center is celebrating the holidays with a twang thanks to the Ukulele Christmas Orchestra. Amateur musicians 18 and older are invited to perform in the free program; this year's theme is Americana. Seating is limited and the event is only for those performing—you'll need to bring your own uke and music stand—so make sure to RSVP beforehand. Beginners are welcome, though you'll need to be able to strum in rhythm while playing these 5 chords in this order: C, Em, F, D7 and G7.
