InstrumentationThe orchestra consists of piccolo, three flutes (the third doubling piccolo), three oboes, English horn, three clarinets in E-flat and B-flat, bass clarinet in B-flat, three bassoons, contrabassoon, six horns in F, four trumpets in C, three trombones, two tubas, timpani, triangle, bass drum, cymbals, glockenspiel, bell on Low E, organ, two harps, and strings (these are in the normal sections of first violin, second violin, viola, cello, and bass, but are frequently divided into many further sub-sections by Strauss' divisi writing). StructureA typical performance lasts half an hour, and is divided into nine sections played with only three clear breaks. Strauss named the sections after selected chapters in the book:
The brass fanfare of the Introduction introduces the "dawn" motif (from "Zarathustra's Prologue", the text of which is included in the printed score) that permeates the structure of the entire work: the motif includes three notes, in intervals of a fifth and octave, as C-G-C [1](also called the Nature-motif).[1] "Of the Backworldsmen" begins in the low strings before opening up into a lyrical passage for the entire section.[1] The following two sections, "Of the Great Yearning" and "Of Joys and Passions", both introduce motifs that are more chromatic in nature.[1] "Of Science" features an unusual fugue beginning in the basses and cellos, which consists of all twelve notes of the chromatic scale.[1] It is one of the very few sections in the orchestral literature where the basses must play a contra-b (lowest b on a piano). "The Convalescent" acts as a reprise of the original motif, and climaxes with a massive chord in the entire orchestra. "The Dance Song" features a very prominent violin solo throughout the section. The end of the "Song of the Night Wanderer" leaves the piece half resolved, with high flutes, piccolos and violins playing a B major chord, while the lower strings pluck a C. One of the major compositional themes of the piece is the contrast between the keys of B major, representing humanity, and C major, representing the universe. Although B and C are adjacent notes, these keys are tonally dissimilar: B major uses five sharps, while C major has none. [1] World Riddle themeThere are two viewpoints about the World Riddle theme (a particular sequence of notes in the melody). Some sources denote the fifth/octave intervals (C-G-C) as the World-Riddle motif.[1] However, other sources refer to the 2 conflicting keys in the final section as representing the World Riddle (C-G-C B-F#-B), with the unresolved harmonic progression being an unfinished or unsolved riddle: the melody does not conclude with a clearly defined dominant note as being either C or B, hence it is unfinished.[1] The ending of the compostion has been described: [1]
Neither the key of C nor the key of B is established as the dominant at the end of the composition. See also
