Thousands of performers have their own roles to play, be they singers, dancers, actors or otherwise.

'With the Beat’ will light up the newly re-named Melbourne Arena, formerly Hisense Arena on September 15.

The show boasts a massive cast including a 75-piece orchestra, 31 principal vocalists, 16 principal dancers, 20 principal ensemble dancers, nine backing vocalists, 44 Victorian state school choir members, 55 specialist dancers and singers, a magician, a puppeteer, 1300 voice choir and 1125 mass dancers.

One of those 16 principal dancers is 15-year-old Wodonga Senior Secondary College student Abbey Copeland.

She auditioned for the highly coveted dancing spot last Decembers, not long after being part of the mass dance troupe in last year's Spectacular.

The Border Danceworks pupil has been travelling to Melbourne every weekend for up to seven ours of rehearsal, and is excited to take the stage in less than a month.

“I was in it last year as part of the mass dance, and seeing the principal dancers I realised it was something I wanted to do,” Abbey said.

“I'm really excited to be a part of it all, coming from a regional area as well it'll be a totally new experience.”

Abbey will perform eight different routines throughout the show – making every minute of rehearsal vital.

Throw in a raft of costume changes and the backstage manoeuvring of thousands of performers, and September 15 becomes a truly massive day for the 15-year-old dancer.

“We're in a lot of dances, each on is really different,” Abbey said.

“We're doing eight routines, so there has been a fair bit to memorise.”

Inspired by Grimm Brothers folk tale 'The Goose Girl’, the Spectacular will take audiences on a journey through a number of different settings, from a Venetian masquerade ball to a steampunk fairground.

School students are also heavily involved off the stage, with 33 secondary students and 90 tertiary and TAFE students working behind the scenes.

Tickets for the Spectacular are on sale now, with performances starting at 9am and 1pm.
