The groups receive coachings from JCM’s roster of world-class musicians in the area and participate in various workshops, tours and concerts.
Program Notes

Camille Saint-Saëns
-
Born: October 9, 1835 — Paris, France
-
Died: December 16, 1921 — Algiers, French Algeria (age 86)
Piano Concerto No. 2 in G minor, Op. 22
III. Presto
Saint-Saëns dashes off this whirlwind finale like a tarantella (a fiery Italian folk dance), bringing the concerto to a breathless close.
Read More
Saint-Saëns wrote this concerto in a rush of just over two weeks for a Paris concert in 1868, joking later that the piece “began like Bach and ended like Offenbach.” The blazing finale is a Presto in the style of a tarantella (a fast Italian dance said to drive away poison), full of swirling runs and relentless drive. Saint-Saëns himself premiered it with the great Anton Rubinstein conducting, dazzling a Parisian audience that wasn’t quite ready for such high-speed fireworks. Tonight, we get just that finale — seven minutes of pure, breathless virtuosity.
COMPOSED
1868 (in just 17 days)
FIRST PERFORMANCE
May 13, 1868 — Paris, Salle Pleyel, with Anton Rubinstein conducting and Saint-Saëns as soloist
APPROX LENGTH
~6 minutes
INSTRUMENTATION
2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 4 horns, 2 trumpets, 3 trombones, timpani, strings, solo piano

Max Bruch
-
Born: January 6, 1838 — Cologne, Prussia (now Germany)
-
Died: October 2, 1920 — Berlin, Germany (age 82)
Concerto for clarinet, viola, and orchestra in E minor, Op. 88
I. Andante con moto
Originally written as a personal gift for his son, Bruch’s concerto—tonight performed by a brother-and-sister duo on violin and viola—carries an extra touch of family spirit.
Read More
Bruch composed this unusual double concerto in 1911 as a personal gift for his son, Max Felix. Instead of the expected flashy opening, the first movement sings with warmth, letting two voices—clarinet and viola—blend in gentle conversation. Tonight, the clarinet part is taken by violin, and the sibling duo on stage adds its own family connection to Bruch’s fatherly gesture. The music flows more like chamber music than a traditional concerto, reminding us that some of the most powerful statements in music come not from fireworks, but from intimacy.
COMPOSED
1911 (dedicated to his son Max Felix Bruch)
FIRST PERFORMANCE
1912, at the Hochschule für Musik, Berlin
APPROX LENGTH
~6–7 minutes

Solo clarinet, solo viola; 2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets, timpani, strings

Max Bruch
-
Born: January 6, 1838 — Cologne, Prussia (now Germany)
-
Died: October 2, 1920 — Berlin, Germany (age 82)
Violin Concerto No. 1 in G minor, Op. 26
III. Finale: Allegro energico
The finale’s surging energy helped make this one of the most popular violin concertos ever written.
Read More
This concerto was Bruch’s calling card, written in his twenties and revised with advice from violinist Joseph Joachim, who premiered it in 1868. The finale bursts open with unstoppable momentum, violin and orchestra locked in a fiery dialogue that barely lets up until the end. Though Bruch wrote many works, this concerto became so popular that he once complained, “I cannot listen to this concerto anymore!” — a sign of how beloved it had already become. For today’s audiences, the energy of this finale is still irresistible.
COMPOSED
1866 (revised 1867)

Camille Saint-Saëns
-
Born: October 9, 1835 — Paris, France
-
Died: December 16, 1921 — Algiers, French Algeria (age 86)
Cello Concerto No. 1 in A minor, Op. 33
III. Tempo primo
Saint-Saëns drives the concerto to a thrilling finish, giving the cello a final burst of passion and brilliance.
Read More
Written in 1872, this concerto helped establish Saint-Saëns as France’s leading composer after the upheavals of the Franco-Prussian War. Instead of treating the cello as an orchestral backdrop, he thrust it into the spotlight from the very first bar. The finale, Tempo primo, circles back to the fiery energy of the opening movement, demanding both agility and stamina from the soloist. Even in excerpt, the concerto’s spirit is unmistakable: bold, brilliant, and deeply French in its flair.
COMPOSED
1872
FIRST PERFORMANCE
January 19, 1873 — Paris, with cellist Auguste Tolbecque and Paris Conservatoire Orchestra
APPROX LENGTH
~4 minutes
INSTRUMENTATION
Solo cello; 2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets, timpani, strings

Maurice Ravel
- Born: March 7, 1875, in Ciboure, a town in the French Basque Country (Pyrénées-Atlantiques, southwestern France).
- Died: December 28, 1937, in Paris, France, at the age of 62.
Tzigane, M. 76a
Ravel’s dazzling Tzigane pushes the violin to its absolute limits in a whirlwind of Gypsy-inspired virtuosity.
Read More
Ravel wrote Tzigane in 1924 for the dazzling violinist Jelly d’Arányi after hearing her play Hungarian gypsy tunes late into the night. Its title literally means “Gypsy,” and the piece opens with an extended solo cadenza that pushes the violin to its limits—double stops, harmonics, wild runs—before the orchestra (or piano, in its original version) finally joins in. What follows is a whirlwind of virtuosity dressed in exotic colors, designed less as a “serious” symphonic statement than as a jaw-dropping showpiece that still amazes audiences a century later.
COMPOSED
1922–1924 (for violinist Jelly d’Arányi)
FIRST PERFORMANCE
January 7, 1868, by violinist Joseph Joachim, conducted by Hermann Levi, with the Gewandhaus Orchestra in Leipzig.

Henri Vieuxtemps
-
Born: February 17, 1820, in Verviers, Belgium.
-
Died: June 6, 1881, in Mustapha, near Algiers (then part of French Algeria), at the age of 61.
Violin Concerto No. 5 in A minor “Le Grétry”, Op. 37
I. Allegro non troppo
III. Allegro con fuoco
Vieuxtemps mixes heartfelt lyricism with violin fireworks in a concerto that earned him the nickname “the French Beethoven of the violin.
Read More
A Belgian violin virtuoso, Vieuxtemps was once called “the French Beethoven of the violin” for the way he balanced poetry with technical brilliance. His Fifth Concerto, written in the late 1850s, pays tribute to the composer Grétry while pushing the solo violin to soaring, athletic heights. The first movement sings with lyrical nobility, while the finale, Allegro con fuoco (“with fire”), unleashes a torrent of energy. For young performers, it’s a chance to show not only finger-breaking skill, but also a composer’s belief that the violin could both speak and dazzle.
COMPOSED
1858–1859
FIRST PERFORMANCE
October 25, 1875, in Boston, conducted by Benjamin Johnson Lang with Hans von Bülow as soloist.
