In celebration of their 50th anniversary year, the Zamir Chorale of Boston is creating a "virtual choir" to sing Louis Lewandowski’s great “Halleluyoh.” The Halleluyoh Virtual Choir will include performances by hundreds of singers from all around the world and incorporate visual history about Lewandowski and his community.

A virtual choir is a performance made up of singers from different locations who come together virtually to share their passion for choral singing in a new and unique way. The concept originated with Eric Whitacre. Virtual choir members simply use their computer to video-record themselves singing their own part, and then upload the recording to YouTube. Those recordings are synchronized to make one enormous virtual choir — an ensemble of hundreds of voices from around the world, united through their love of this music.

Participation in the virtual choir is open to all, now through June 30, 2018.
