Sydney Contemporary Orchestra

Welcome to our concert of Young Virtuosos 2022.

Associated with the Hills Blossom Festival, this concert is a showcase of our young musician’s improvements and achievements after terms of training. This concert is divided into two parts. In the first part, the young musicians of the Sydney Hills Junior Orchestra will perform some solo pieces accompanied by the orchestra.  They are playing not as masters yet, but you still can see their virtuosities at such little ages, and I am sure one day they will be.

In the second part, the Sydney Hills Youth Orchestra will perform a piece of classical music by Mozart and a piece of romantic music by Carl Nelson. You will be surprised by this group of young musicians’ interpretations of these different styles both technically and musically.

Sincere thanks to our management team without whom nothing could have been done.

I would like to thank the Hills Shire Council and Baulkham Hills High School for their great support.

From the Mayor of the Hills Shire – 


It is my absolute pleasure to welcome you to the 2022 Young Virtuosos Concert as part of our Orange Blossom Festival.

The last few years have reminded us how important and special it is to gather together and share our love for music.

The Young Virtuosos is a wonderful program that allows budding young musicians to attempt their first solo while accompanied by an orchestra. I would like to thank our talented musicians from the Sydney Hills Youth Orchestra and the Sydney Hills Junior Orchestra for taking this daunting first step and allowing us to share it with you.

I would also like to thank Dr Brian Koo, their founding conductor, for inspiring these young adults and children to follow their passion for classical music and enhance their craft.

My sincere thanks as well to everyone else who has brought this concert into fruition, including parents and guardians – it takes a village.

Enjoy the performance and I hope to see you all at our other Orange Blossom Festival events.

Mayor of The Hills Shire,
Dr Peter Gangemi

Wolfgang Amadeus Mozart

Divertimento  No.24

Mozart composed the Divertimento, K. 136, in 1772 when he was 16-year-old.

This Divertimento is in three movements.  The opening Allegro, in sonata form, centers around a delightful, charming theme that ends with an amusing little dynamic retreat. The development moves into the minor mode, surprising the listener with a second episode where a less inventive which leads to the opening theme. The Andante is typically warm and elegant, its two halves contrasted by a brief acceleration in the accompaniment’s pulse. A spirited Presto finale brings the Divertimento, a fine example of a genre traditionally designated as “light” music, to a close.

Wolfgang Amadeus Mozart, a genius, one of the three great composers in the Classical period among Hayden and Beethoven, was born in Salzburg, Austria. He composed his first piece of music at age five and he wrote his first opera when he was twelve. By the time Wolfgang was 6, he was an excellent pianist and violinist.

Mozart was only 35 when he died. During his short life, he composed in all different musical forms, including operas, symphonies, concertos, masses, and chamber music.

Carl Nielsen

Little Suite for Strings (Nonet), Op.1

Carl Nielsen composed this suite in 1888.

It fulfills or style of the Romantic era – rich harmony, irregular phrases, complex texture, unusual division of instrumentations as well as Northern European folk music influences.

It begins in a serious vein with a dark and moody Praeludium. The graceful middle movement, Intermezzo, is full of good humor. It commences with a lilting waltz and then is followed by a more energetic dance section which has a vague Viennese quality to it. The finale begins with a short restatement of the gloomy Praeludium but soon the music takes wing, rushing into a high-flying Allegro con brio of exciting exuberance. Though momentarily, a few storm clouds appear, the music sweeps forward to a triumphant conclusion.

Nielsen was born on the island of Fyn (Funen) and eventually entered the Royal Danish Conservatory in Copenhagen where he studied violin and composition with the famous composer Niels Gade. He himself became Denmark’s leading composer during the first part of the 20th century.
