Pierre Amoyal


Pierre Amoyal is well known to music lovers. He has played with the greatest conductors and orchestras in the most prestigious concert halls of the world. This virtuoso is also the lucky owner of the one of the most beautiful violins ever made : the famous “Kochanski“, a Stradivarius that was stolen from him in 1987, and which was miraculously recovered four years later by the Italian “Carabinieri”.

When Pierre Amoyal was only twelve years old, he completed his studies at the Paris Conservatory with a First Prize. The prodigy then left for Los Angeles to study with the legendary Jascha Heifetz. The two spent five intense years together, culminated by chamber music concerts and recordings with the cellist, Gregor Piatigorski.

At the age of 22, he made his European debut with the late Sir Georg Solti and the Orchestre de Paris, followed by appearances in all of the major European capitals, as well as in the USA, Canada, Mexico, South America and in the Far East. Amoyal has played under the most important conductors of the last three decades: von Karajan, Ozawa, Boulez, Maazel, Solti, Pretre, Sanderling, Roshdestvensky, Rattle, and Mung Whun Chung, to name only a few.
He was the youngest musician ever to be nominated as a professor at the Paris Conservatory.
Following his move to Switzerland, he was Professor at the Lausanne Conservatory, Haute Ecole de Musique. He was appointed as University Professor at the Mozarteum in Salzburg. Pierre Amoyal is a very touching example of a virtuoso whose exceptional talents never hindered his love of hard work.

Hyung-Ki Joo

Korea / Great Britain

Hyung-ki Joo was born. He is British, but looks Korean, or the other way around, or both. On the Internet, related searches for #Hyung-ki_Joo include: #Composer, #Pianist, #Conductor, #InspiringStudents, #YouTubeSensation, #KaratePiano, #FastestToothbrusherInTheWorld, #WatchedMissionImpossibleEightTimesInARow, #TaylorSwift’sSecretAsianFantasy, #Pomegranate, and #Aadvark. Hyung-ki, pro­nounced forever, YOUNG-KEY with an “H” in front, is also the only Korean Jew, (spelt J-O-O), in the world.

He started piano lessons at the age of eight and a quarter, and two years later won a place at the Yehudi Menuhin School. There, he discovered that he was among geniuses and child prodigies and was convinced he would be kicked out of the school. In the end, he was never kicked out but teachers and fellow students, such as Aleksey Igudesman, did kick him around in various parts of his anatomy, making the future of any offspring rather bleak. No matter how difficult those seven years at the school may have been, it only strengthened his love of music, and a while after graduation, he was chosen by Yehudi Menuhin himself to perform as soloist for his eightieth birthday concert at the Barbican Hall, London.

Hyung-ki’s teachers have included Nina Svetlanova, Beryl Kington, Peter Norris, Seta Tanyel, Irina Zaritskaya, Vlado Perlemuter, Oleg Maisenberg, Richard Goode, and Ferenc Rados. He is eternally thankful to them for all their time, generousity, and sharing the gift of their knowledge.

Raimund Trenkler


Raimund Trenkler was born in 1962 and grew up in Berlin. After completing his cello studies in London, he took up the position of first solo cellist with the Seoul Philharmonic Orchestra in 1990. In 1991, he founded the “Cellissimo” ensemble of five cellists, with which he performed at international festivals worldwide.

A year later, together with Marta Casals Istomin – the widow of Pablo Casals – and Mstislav Rostropovich, he developed the idea of celebrating Pablo Casals and his message of universal humanity by bringing together musicians of all generations from across the globe in Kronberg to make music together and learn from one another. To this end, Trenkler and a group of private sponsors founded Kronberg Academy in February 1993.

Today at Kronberg Academy, the most renowned teachers in their fields train gifted young artists to become soloists in the disciplines of violin, viola and cello. In so doing, the Academy sees its role as helping these young musicians to become the world’s best, whilst also assisting them to develop an awareness of their responsibility to society. Since autumn 2017, on Trenkler’s initiative and under his leadership, Kronberg Academy has been constructing the Casals Forum, a unique chamber music venue for some 600 audience members that will also house a new study and administration centre. The planned opening of the two buildings is scheduled for 2022.

Raimund Trenkler is Chairman of the Board of the Kronberg Academy Foundation, as well as Chair of the Rostropovich Cello Foundation and the Gidon Kremer Stiftung. He is frequently in demand as a jury member at international violin, viola and cello competitions.
