'Carl Flesch is one of the greatest artists of the present day, in fact, many authorities place him on a level with Ysaye. He is a very simple gentleman, and does all his work in real earnest.

I shall never forget his interpretation of Brahms's Concerto with Mengelberg's Orchestra at Arnheim, not very long ago, and I strongly advise the readers of The Strad not to omit hearing him if they have the chance of doing so.'

'Apart from the respect and admiration which we pupils had for Professor Carl Flesch as a superb teacher, we were all quite in awe whenever he took up the violin and accorded us the privilege of listening to his playing.'

'My teacher, Aida Stucki-Piraccini, studied with Carl Flesch in the 1940's, and became a wonderful violinist. She carries her enthusiasm for the splendid master in her heart to this day, and, as a matter of course, she continues to instruct her pupils in the spirit of the Flesch tradition. I, therefore, look upon myself as an artistic granddaughter of Carl Flesch, for even now, his work again and again provides inspiration and impetus for my own violinistic development.

...

It is a personal honor for me, in this way, to render thanks to Carl Flesch, one of the very greatest teachers of our art, and to combine this expression of gratitude with the hope that Flesch's seed will continue to bear fruit in the future.'

'The distinguished Hungarian violinist Carl Flesch is remembered today as one of this century's greatest violin pedagogues. Flesch established the principles for a "modern" analytical approach to violin playing. Having a pervasive influence in his teaching, this violinist was also important solo and chamber music performer.'

'The Art of Carl Flesch is the most important work on this subject which has appeared since the "Art du violon" of Baillot.'

'Carl Flesch's ability to combine clarity of thought, profound knowledge and artistry, along with immense mastery of the craft cenrtaily left an indelible mark on his students, and indeed on anyone who became acquainted with his approach and outlook. For those of us, who had the opportunity and good fortune to study with Carl Flesch for some length of time, the experience was a truly pivotal one.'

'I strongly believe that Carl Flesch will for ever remain the Father of the scientific approach to violin teaching and we, as well as future generations, should be grateful for his outstanding achievment.'

'... With your work you have given the violinists a bible, in whicht teachers and players will study as long as the violin will be played on this earth. Nothing connected with the violin or with violin playing has been overlooked and for every single thing you find a thoroughly convincing reply.'

'Seldom in my life have I heard a more dazzling or brilliant performance of the fiendishly difficult Ernst Concerto in F sharp. The same is true of his unforgetable rendition of Sarasate's Bohemian Airs and Wieniawski's Polonaise in D. Yet he rose to international fame performing concertos by Bach, Brahms and Beethoven, works he also edited revealing most remarkable fingerings and bowings. If ever there was a stunning and surprising personality during the last century, it certainly was Carl Flesch's.'

'... the first publication of the long-awaited posthumous work of Carl Flesch, the 'High School of Violin Fingering', constitutes a major event that will become a significant date in the history of violin playing.'

...
I think that Flesch was the rare example of musician who could combine the German and French traditions in his interpretations.'

'Winning a competition such as the Carl Flesch surely helps any young musician to start a career. It gave me the opportunity to play in London at Wigmore Hall few months after the competition, and that concert gave me the chance to get a good agent, who helped me very much in starting my career.'
