To this day Gustav Mahler understands how to make others tremble. The dispatchers and managers of the finance departments of orchestras, whose artistic directors would like to put a Mahler Symphony on the program again. Trembling, because it is clear: that will be expensive again in view of the often gigantic, often also exotic instruments that Mahler has used for his refined sound effects. Again and again it has rained colleagues of the master to transform his symphonies to small formats. Where, from an artistic point of view, the main thing was to try to solve the content of the opulent packaging, so to speak, without distorting the musical message. And so the Austrian composer and conductor Erwin Stein, a Schoenberg pupil, created in 1921 a chamber music version of the 4th Symphony for woodwinds, string quintet, percussion, harmonium and piano. The music of Mahler, and in particular the Symphony No. 4, bathing in a very romantic light, in an extremely fiery and at the same time serene setting, almost classically situated between the monumental symphonies No. 3 and No. 5, left much more than any others to a revision. The work interpreted in this form provides new insights and experiences and proves once again that beauty and the poetic and expressive meaning of a masterpiece can be rediscovered infinitely new.
