Memorial is an epic funeral march like piece, composed by Michael Nyman around 1984 1985. This composition is one of the most praised in the work of Michael Nyman and has been reprised in Michael Nyman Band s The Essential Michael Nyman Band and The Very Best of Michael Nyman 1990 2001 . The work premiered on 15 June 1985. Background Nyman utilized a death march in his earlier work, Drowning by Numbers , and revives the scheme for Memorial , clearly setting death and its emotional impact as the main theme of the composition. Indeed, Nyman explicitly dedicated Memorial to the memory of the Juventus F.C. fans killed in the Heysel Stadium Disaster Heysel Stadium tragedy , in May 1985. The composition borrowed a musical phrase from Baroque composer Henry Purcell s King Arthur opera King Arthur , the prelude to The Cold Genius Arises, but the phrase is repeated in countless times, in a minimalist music minimalist fashion. The composition is dominated for the first two thirds by the string and horn sections, backed up by bass guitar , and a drummer. Soprano Sarah Leonard comes in only in the last third of section, and her performance mainly consists of long wordless complaints, adding a dramatic effect to the composition. Her song is continuously an octave higher than the rest of the orchestra, thus creating a haunting effect that suggests pain and sorrow.

Unreferenced date December 2009 Timbre composition is the art of creating new timbres. It is often performed electronically, either by combining sinewaves additive synthesis or by filtering out harmonics from more complex waves subtractive synthesis . Timbre composition is also significant for players of the electric guitar . The guitarist s relative proximity to his or her amplifier alters the sound produced. The sound can be modified further via Equalization equalizers , audio filter filters , and various effects pedals . Timbre composition with acoustic instruments is usually very subtle. Minute altercations in performance change the sound produced by the instrument. Percussionists use specific sticks and mallets to yield desired timbres. Players of wind instruments alter the tone simply by changing the pressure of their lips. One could argue that the act of choosing which instrument to play or write for is in itself timbre composition. Timbre composition is used in vocal techniques such as throat singing where the main focus of the music is timbre as opposed to pitch.

In particular, in the 1940s the format Composition letter was used for various compositions of the relatively novel explosive RDX, such as Composition B and other variants. The original material was developed by the British during World War II , and standardised as Composition C when introduced to US service. This material consisted of 88.3 RDX and a mineral oil based plasticiser and phlegmatized phlegmatiser . It suffered from a relatively limited range of serviceable temperatures, and was replaced by Composition C 2 around 1943. Composition C 2 contained a slightly smaller proportion of RDX, but used an explosive plasticiser, which contained tetryl ... trinitrotoluene , dinitrotoluene and mononitrotoluene , and a trace of solvent. While Composition C 2 had a much wider serviceable temperature range than Composition C, it could not be stored at elevated temperatures. Consequently it was replaced around 1944 by Composition C 3.

Traditionally the back cover of such a book the inside back cover for most had a table of the weights and measures of the English system printed on it for children to refer to, however this feature has become diminished in countries that have adopted the metric system . Sometimes a multiplication table or grammar or punctuation tips are also found on the inside back cover. They are bookbinding bound in a similar fashion to book s, consisting of sheets about twice as wide as a single page, folded along the spine, and traditionally sewn together. Such a bookbinding signature is much thicker than that which is used for a book, however. Composition books are thus more durable than spiral notebook s or those with perforated pages. Unlike these, however, individual pages are not intended to be torn out of a composition book. The last step in their production is trimming the edges of the book, conventionally rounding the two loose corners. One conventional size of these is 9 inches 247.6 mm high by 7 inches 197 mm across, but there are some now made in China which are 247 mm high by 190 mm across.
