compositional period for Bruckner within the realm of the "Major Tetralogy". However, the Sixth Symphony has extensive ties to the Fourth and Fifth Symphonies and is considered to have been composed as a reflective, humanistic response to its two direct symphonic predecessors. It has even been dubbed the Philosophical symphony by critics for this reason. Compositional hallmarks Bruckner's symphonies encompass many techniques but the one unwavering hallmark of his symphonic compositions is a singular formal pattern that underwent very little variation over the course of his symphonic repertory. In fact, their four extended movements are indebted to the structure and thematic treatment in the late works of Beethoven. The only large-scale diversion from this formal scheme in the Sixth Symphony is Bruckner's use of sonata form in the second movement instead of his usual large-scale ternary form. Thematically speaking, there are two distinct varieties of themes in Bruckner's symphonies. First, there are themes that are clearly defined in shape and then there are the themes that operate more as motives with a shorter length and a more open-ended shape, as is typical of the Sixth Symphony. Another characteristic thematic feature of Bruckner's symphonies is the intimate relationship between the outer two movements, though there is typically more of an emphasis on thematic contrast within the first movement. Specifically, the amplification of the exposition of the first movement consists of two subsidiary themes as well as the primary theme, which are subsequently developed, a technique that is considered uniquely Brucknerian. Other characteristics that are found in Bruckner's symphonies (especially the Sixth) include the extensive treatment of the dominant seventh chord as a German sixth chord in a new key, usage of cadences as a decisive factor in daring modulations, the treatment of organ points as pivotal to the harmony and structure, chains of harmonic sequences, and, most notably, extensive use of rhythmic motives, especially the characteristic Bruckner rhythm, a rhythm consisting of two fourths and three quarter notes, or vice versa. This rhythm dominated most of the Fourth Symphony and was practically nonexistent in the Fifth Symphony, but becomes nothing short of a driving force in the Sixth Symphony; the metric complexities generated by this unique rhythmic grouping are more pronounced in the first movement of the Sixth Symphony than in any of Bruckner's other compositions. Orchestration The orchestration of the Sixth Symphony complies with Bruckner's customary, albeit peculiar, techniques. Just
