"Tandler’s compositions from the time of his studies and shortly afterwards built on what he learned at university, and the most striking of them was String Quartet No. 1 (1974), which was heard also at the Music Festival in Brno. His essential ideal was to create things according to hitherto undefined rules that were rooted in classicist simplicity, transparency, respect for order, and purity of style. He sought to throw off the shackles of constructivism; musical spontaneity was always close to his heart. At the same time, in free atonality he was seeking a new method of expression, language without alien elements. Probably influenced by the composition of a great deal of instructive literature, which had to be technically undemanding and easily grasped, he sought a simplification of the musical language. This process culminated in his final compositions: Suite for Solo Flute (1994), Adlibs for a Positive (1991), Misse brevis (1996), and especially String Quartet No. 3 (1997) in a Tandleresque New Simplicity."
