On Sunday morning, there’s going to be a joyful blast at the Alex Aidekman Family Jewish Community Campus in Whippany. Hundreds of people have signed up to blow shofars in unison and, hopefully, make history.

The Great Shofar Blowout is a high decibel prelude to Rosh Hashanah, the Jewish New Year, which begins on Wednesday evening. Organizers are aspiring to shatter the Guinness World Record for simultaneous sounding of the ancient instrument.

It will be no small feat for Whippany to top the current record holder, Swampscott, Massachusetts, where 796 horns were blown in in 2006.

The shofar is an animal horn that is sounded at synagogues on the high holidays. It creates a shrill, wailing tone that is meant to awaken the spirit and prompt a personal growth in the coming year. Although the person who plays the instrument is traditionally a soloist at conservative and orthodox temples, reform synagogues often have shofar ensembles to create a “surround sound” experience that reverberates throughout the temple.

Registration for the Great Shofar Blowout is scheduled to begin at 9 a.m. on Sunday. Participants may bring their own horns or purchase one at the Jewish center. The shofars will blow at 11 a.m., followed by a picnic and a performance by the Mama Doni Band. The group is going to play bluegrass music inspired by Jewish New Year traditions.
