Title: Nummer 5
Content:  A first version of the work was written by March 1953, but it was only after his friend Karlheinz Stockhausen had finished his Studie I in November that Goeyvaerts was able to come to Cologne to realise his work. In the meantime, Goeyvaerts made a revised version of his score, probably in the Autumn, with a much more complex web of proportions over the entire composition that appears to have been influenced by Stockhausen's Studie. Goeyvaerts was given technical assistance by Stockhausen in realising his work. The premiere of Goeyvarts's composition was given on 19 October 1954 on the inaugural concert of works produced in the WDR studio, together with the first performances of six other pieces: Stockhausen's Studie I and Studie II, Herbert Eimert's Glockenspiel and Etüde über Tongemische, Paul Gredinger's Formanten I/II, and Henri Pousseur's Seismogramme. Eimert emphatically titled these pieces "Die sieben Stücke" (The Seven Pieces), and long maintained that this was the first concert of electronic music. In retrospect, Goeyvaerts was unhappy with Nummer 5 as a finished product, because it demonstrated that absolute certainty lay outside his grasp.
Title: Nine Short Pieces for Piano
Content:  Nine Short Pieces for Piano is a set of small-scale compositions by Douglas Lilburn. They were written around 1965 and published in 1969, chosen in 1967 with pianist Margaret Nielsen from a folder of similarly brief manuscripts labelled "crotchety at 51". They are about twelve minutes long in total. These pieces were among the last that Lilburn composed for acoustic instruments; he began to focus on electronic experimentation in 1965. Each piece is constructed from one or two concise motifs. With a harmonic and rhythmic texture drawing from his electronic music, these pieces explore the full extent of the piano's range and dynamics; "looking as modern music should look". They are also notated in an unorthodox manner.
Title: Miscellaneous solo piano compositions (Rachmaninoff)
Content:  The composer Sergei Rachmaninoff produced a number of solo piano pieces that were either lost, unpublished, or not assigned an opus number. While often disregarded in the concert repertoire, they are nevertheless part of his oeuvre. Sixteen of these pieces are extant; all others are lost. Ten of these pieces were composed before he completed his Piano Concerto No. 1, his first opus, and the rest interspersed throughout his later life. In these casual works, he draws upon the influence of other composers, including Frédéric Chopin and Pyotr Tchaikovsky. The more substantial works, the Three Nocturnes and Four Pieces, are sets of well-thought out pieces that are his first attempts at cohesive structure among multiple pieces. Oriental Sketch and Prelude in D minor, two pieces he composed very late in his life, are short works that exemplify his style as a mature composer. Whether completed as a child or adult, these pieces cover a wide spectrum of forms while maintaining his characteristic Russian style.
Title: Compositions 1960
Content:  The last numbered piece in the cycle. This piece, like #13, is also dedicated to Richard Huelsenbeck. Instructions: This piece is little whirlpools out in the middle of the ocean. It is dated 9:05 A.M., December 25, 1960.
Title: Three Pieces for Orchestra (Berg)
Content:  Alban Berg composed his Three Pieces for Orchestra (German: Drei Orchesterstücke), Op. 6, between 1913 and 1915. They are dedicated to his teacher Arnold Schoenberg.

Title: Three Pieces for Orchestra (Berg)
Content:  Berg composed the Three Pieces between 1913 and 1915. Studying with Arnold Schönberg, he had composed mainly lieder such as Altenberg Lieder, and thought about a larger composition, such as a suite or a symphony. He settled with orchestral pieces, and worked on them in Trahütten, Styria, in summer, where his parents-in-law had a country estate. The work was completed on 23 August 1914. Berg dedicated it "to my teacher and friend Arnold Schönberg with immeasurable gratitude and love", and sent it to Schönberg as a gift for his 40th birthday, on 13 September 1914. In a letter he expanded: "I have truly striven to give my best, to follow all your incentives and suggestions, whereby the unforgettable, yea revolutionising experiences of the Amsterdam rehearsals and thorough study of your orchestra pieces served me boundlessly and sharpened my self-criticism more and more." The premiere of the first two pieces was held in Berlin on 5 June 1923 during an Austrian Music Week, conducted by Anton Webern. It was not until 14 April 1930 that the complete composition was played, in its revised form, by the Oldenburger Landesorchester conducted by Johannes Schüler.
