Tutti is a massively participatory music-making experience for members of a large audience using their cellphones as simple musical instruments. It started as Danielle Penny (EECS '17)'s senior UAP/thesis project and has transformed into a collaboration between Eran Egozy, Evan Ziporyn, and Nick Joliat that will be featured in the Boston Event of the MIT Campaign for a Better World on September 28, 2017.

Audience members will play a new composition by Ziporyn titled Engineered Engineers (based on the famous Engineer's Drinking Song often sung at MIT). Audience members are divided into four orchestras sections (Winds, Strings, Brass, and Percussion). Each audience member's cellphone is then transformed into a one-button instrument that can play the appropriate notes for the chosen part.

The core technology behind Tutti requires all audience phones (over 1000 phones) to be precisely sychronized to a common clock so that they can all play together in a coordinated fashion - hence the name Tutti (an Italian musical term meaning all together).
