YouTube has launched its second international orchestra project. Musicians have until 28 November to submit their audition videos for the chance to be part of the YouTube Symphony Orchestra performing in Sydney next March.

The first YouTube Symphony Orchestra brought together more than 90 musicians from 30 countries for a week in New York in April 2009, culminating in a performance at Carnegie Hall. Up to 96 musicians will be chosen for the new orchestra, which will travel to Sydney and cap a week of rehearsals and masterclasses with a performance at Sydney Opera House.

Solo improvisers are also being invited to audition to join the 2011 orchestra. Two will be chosen to play live with the orchestra, and two runners-up will perform remotely by streaming video over the internet.

The winning musicians will be chosen by public vote via YouTube from a shortlist of 300 orchestra hopefuls and 100 improvisers. Details of how to submit auditions can be found at
