AMY Brookman's violin loves Melbourne.

The Australian Chamber Orchestra string ensemble violinist said her Roth violin, made in Germany, had a clearer sound when in a colder climate.

"My violin likes cold, wet weather. It sounds warmer and it's easier to play for some reason," she said.

"Ever since I moved to Melbourne it's been easier to play."

But the changes she has seen in her instrument in a colder environment are not only about its sound.

"In wet weather, the varnish has a darker red colour," she said.

"When it's really hot, the timber is lighter and looses some of that deep red colour. It's like it's alive."

Ms Brookman, a violin player from the Gold Coast, is touring regional NSW and Queensland with ACO2.

Formed by 17 professional musicians, the ACO2's string ensemble delivers the ACO's regional touring and education programs.

It connects the elite musicians of the ACO with Australia's most talented young professional musicians at the outset of their careers, creating a combined ensemble with a fresh, energetic performance style.

This year, the ACO2 has invited lead violin player Benjamin Schmidt to be its guest director.

Schmidt has selected a program that includes Johan Sebastian Bach's Concerto for Violin in E major, Pyotr Ilyich Tchaikovsky's Souvenir de Florence, Samuel Barber's Adagio for Strings, and Herbert Berger's Metropoles Suite for Violin and Strings.

Five emerging artists are chosen every year to be part of ACO2 and complete the tour with some of the more experienced musicians.

Amy Brookman is one of them, and she is very excited to be in this year's tour.

"There is a new work that has been written only last year by (Herbert) Berger and it's very jazz-influenced," she said of the program.

"It's such a different piece of music, totally different to what I am used to play."

The ACO2 is coming to Gladstone on May 24 at the GECC from 2.30pm.

Tickets are $44 for adults and $20 for students.
