Founding Conductor, Artistic & Executive Director
Sydney Contemporary Orchestra

Welcome to our Christmas Concert 2022.

This concert is divided into two parts. In the first part, the young musicians of the Sydney Hills Junior Orchestra will perform some pieces specially written for the young string groups. These budding young musicians will be growing from this simple music step by step moving up through our training.

In the second part, the Sydney Hills Youth Orchestra will perform a famous piece of Max Bruch – Kol Nidrie Adagio for cello and orchestra performed by Roger Goch, a very talented young cellist. The small group will also play Mozart’s Divertimento No 28. a very challenging piece of music that push these young musicians up to a high stander.

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.

Max Bruch

Kol Nidrei

Adagio for Cello
with Orchestra and Harp

Max Bruch was born in Cologne, where he had his early musical training, and went on to a career as a teacher, conductor, and composer. From 1891 he was principally occupied in Berlin as a professor of composition at the Berlin Academy. Known in his lifetime as a composer of choral works, he is now remembered chiefly for a handful of orchestral compositions.

The Kol Nidre melody was as exotic a tune as a German Protestant was likely to come across, and Bruch got it more or less the same way Prokofiev got his “Hebrew themes”: it was handed to him by a member of a choir that he directed. He composed this work for cello and orchestra in 1881, the year he went to England to take up the post of director of the Liverpool Philharmonic.

Kol Nidre (“all vows”) is a haunting and rather mysterious Aramaic prayer sung toward the beginning of the Yom Kippur Eve service

(and indeed, is such a prominent part of this most important day in the Jewish calendar that Yom Kippur Eve is often called simply “Kol Nidre”). The prayer is a disavowal, in advance, of any vows to God that may be made in the coming year. Many scholars believe that it became a prominent part of the service during the middle ages, prospectively nullifying oaths of conversion when Jews were often forced to choose between death and conversion to Christianity; others believe its prominence results simply from the captivating nature of its long, wandering melody. Bruch’s Kol Nidrei (Bruch spelled it thus in German; the “correct” spelling is in the Hebrew alphabet) uses the first few phrases of the traditional song. Like Prokofiev’s overture, it does not attempt to maintain a “Jewish” atmosphere for long, heading quickly into the Schumannesque sonic world of mid-20th century Germany, particularly when it moves into major keys.

Wolfgang Amadeus Mozart

Divertimento  No.15

The Divertimento No. 15 in B-flat major, K. 287, is a divertimento by Wolfgang Amadeus Mozart. He composed in 1777 for the name day of Countess Maria Antonia Lodron. It is also known as the Lodronische Nachtmusik Nr. 2.

The work consists of six movements:

Allegro (in B-flat major and in sonata form)

Tema con variazioni (Andante) (theme and 6 variations, where the theme and all the variations are in F major)

Menuetto – Trio (in B-flat major and in ternary form, trio in G minor)

Adagio (in E-flat major and in sonata form)

Menuetto – Trio (in B-flat major and in ternary form, trio in E-flat major)

Andante – Allegro molto (in B-flat major, beginning with an introductory instrumental recitative, and in sonata rondo form).

Tonight we will only play  four movements:

I   Allegro
II Thema mit Variationoen
III Menuetto
IV Andante, Allegro molto
