A missal is a liturgical book containing instructions and texts necessary for the celebration of Mass throughout the liturgical year. Versions differ across liturgical tradition, period, and purpose, with some missals intended to enable a priest to celebrate Mass publicly and others for private and lay use. The texts of the most common Eucharistic liturgy in the world, the Catholic Church's Mass of Paul VI of the Roman Rite, are contained in the 1970 edition of the Roman Missal. Missals have also been published for earlier forms of the Roman Rite and other Latin liturgical rites. Other liturgical books typically contain the Eucharistic liturgies of other ritual traditions, but missals exist for the Byzantine Rites, Eastern Orthodox Western Rites, and Anglican liturgies. History Before the compilation of such books, several books were used when celebrating Mass. These included the gradual (texts mainly from the Psalms, with musical notes added), the evangelary or gospel book, the epistolary with texts from other parts of the New Testament, mainly the epistles (letters) of Saint Paul, and the sacramentary...

Jazz on a Summer's Day is a 1959 concert film set at the 1958 Newport Jazz Festival in Newport, Rhode Island (which took place from July 3 to July 6 of 1958). The film was directed by commercial and fashion photographer Bert Stern and Aram Avakian, who also edited the film. The Columbia Records jazz producer, George Avakian, was the musical director of the film. The film mixes images of water and the city with the performers and audience at the festival. It also features scenes of the 1958 America's Cup yacht races. The film is largely without dialog or narration (except for periodic announcements by emcee Willis Conover). The film features performances by Jimmy Giuffre; Thelonious Monk; Sonny Stitt; Anita O'Day; Dinah Washington; Gerry Mulligan; Chuck Berry; Chico Hamilton, with Eric Dolphy; and Louis Armstrong, with Jack Teagarden.

The pyroxenes (commonly abbreviated Px) are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks. Pyroxenes have the general formula XY(Si,Al)2O6, where X represents calcium (Ca), sodium (Na), iron (Fe II) or magnesium (Mg) and more rarely zinc, manganese or lithium, and Y represents ions of smaller size, such as chromium (Cr), aluminium (Al), magnesium (Mg), cobalt (Co), manganese (Mn), scandium (Sc), titanium (Ti), vanadium (V) or even iron (Fe II or Fe III). Although aluminium substitutes extensively for silicon in silicates such as feldspars and amphiboles, the substitution occurs only to a limited extent in most pyroxenes. They share a common structure consisting of single chains of silica tetrahedra. Pyroxenes that crystallize in the monoclinic system are known as clinopyroxenes and those that crystallize in the orthorhombic system are known as orthopyroxenes. The name pyroxene is derived from the Ancient Greek words for 'fire' (πυρ, ...
