Full dynamic reactions in the main links of big band saw machines

In this study, the full dynamic reactions in the bearing supports of the leading wheel of big band saw machines are determined. These reactions are caused by both the external loads and the kinematic and mass characteristics of the rotating disk. Expressions for calculating the dynamic reactions caused by external forces and moments that occur in the operating mode are obtained. The influence of the kinematic and mass characteristics of the rotating disk is studied and expressions for calculating the dynamic reactions caused by these characteristics are obtained. Expressions for calculating the full dynamic reactions that load the bearing supports of the leading wheel are obtained. With the help of these expressions, the parameters of the band saw machine can be selected in such a way as to ensure a minimum load on the shaft and bearings.

A Study of Long-Form Works for the Jazz Ensemble

<p>Reflections (In Mosaic) is a long-form work written for a modern jazz orchestra. While made up of seven smaller parts, it is intended to be listened to as a single continuous performance. Reflections (In Mosaic) serves as an exploration into formal structures more complex than the standard blues and cyclical AABA forms. This is achieved through the use of inter-related musical themes, transitional material that develops musical themes and propels the story of the piece forward, programmatic themes, and a consideration towards a more integrative approach to improvised sections in a modern jazz composition context. This exegesis features a comprehensive musical and topical analysis of four case studies: Duke Ellington’s Harlem (1951), Charles Mingus’s Fables of Faubus (1959), Gunther Schuller’s Seven Studies on Themes of Paul Klee (1959), and Pat Metheny and Lyle Mays’s The Way Up (2005). In my analysis I examine the features of long-form works from a range of different angles through discussions on: (1) the formal features of the symphonic jazz genre and the integration of concert-style gestures into the jazz big band tradition, (2) the role performance and improvisation can have in communicating an idea within a composed structure, (3) the use of programmatic themes, and (4) a model for a structural design which draws on comparisons to narrative structure. Of particular importance to my compositional project is the use of a programmatic theme. Reflections is directly inspired by the film Magnolia (1999), written and directed by Paul Thomas Anderson. I do not attempt to mirror the narrative or structure of the film in Reflections but, instead, loosely base the composition on the film’s characters and topical themes. The culmination of this exegesis is a discussion of how the four case studies informed my own compositional processes.</p>

Orkestra Rumpilezz

Chapter 3 presents the book’s first case study, Orkestra Rumpilezz, a big band mixing jazz with emblematic Afro-Bahian genres such as Candomblé, carnival music (ijexá and samba reggae), samba de roda, and capoeira. It opens with a discussion of composer-director Letieres Leite’s trajectory in Brazil and Europe and his views on Africa and the liminal status of jazz in Bahia, as an African diasporic genre and, simultaneously, US America’s classical music. This is followed by an analysis of how the orchestra spotlights percussion and percussionists in its performances and links them to the polemic notion of racial democracy in Brazil. A number of performance practices (layout of musicians on stage, colors and styles of costumes, visual symbols, instrumentation, physical movement, speech between pieces) are connected with the tropes of embodiment, spirituality, and spontaneity.

Orkestra Rumpilezz

Chapter 4 continues the discussion of Orkestra Rumpilezz, focusing on how it materializes Letieres Leite’s rhetoric about African rhythmic complexity. Two strategies for increasing rhythmic complexity are discussed: the transfer of drum patterns from Candomblé to the big band to form polyphonic textures; and the transformation of traditional timelines (clave-like patterns) borrowed from Candomblé and carnival music, including rotation (shifting the timeline’s reference point), truncation, and superimposing two versions of the same timeline, a phenomenon that is labeled staggered timeline alignment. The chapter theorizes unique cases of timeline usage, comparing and contrasting them with well-known studies of clave in other parts of the black Atlantic.

Africanness in Action

This book discusses how musicians from Bahia, an emblematic African diasporic location in northeastern Brazil, think about, discuss, compose, rehearse, perform, and stage music inspired by what they perceive to be their own African ancestry. It argues that these musicians assert Afro-Brazilian identities and connect to the African continent and other diasporic places by creatively engaging essentialized notions about African music and culture: instead of mechanically reproducing these tropes, they emphasize them or downplay them. The book theorizes these preconceived notions about African music, culture, and performance as tropes of Africanness, emphasizing that they exist in two interrelated realms: as essentialist ideas in discourse and as concrete practices and sounds. Six commonly encountered tropes of African music are analyzed: the notions that its most important parameter is rhythm and that it is dominated by percussion; that it is meant to be danced to or deeply embodied rather than intellectualized; that it always touches on the sacred; that it is spontaneous and improvisatory; and that it reflects communalism rather than individualism. Through four case studies from Bahia (a jazz big band called Orkestra Rumpilezz, a symphony orchestra called the Orquestra Afrosinfônica, and two berimbau orchestras led by capoeira practitioners), the book demonstrates the nuances of musical creation in the African diaspora, acknowledging the genuine impact that essentialisms have on Bahian music while showing that they may not be an essential part of the musicians’ African roots.

ESTETIKA PERMAINAN MUSIK BARAT PADA BIG BAND SALAMANDER

<p>This article describes the aesthetics of the big band jazz music by Salamander Big Band. Aesthetics is a study of the processes that occur in three basic elements: aesthetic objects, aesthetic subjects, and aesthetic values related to aesthetic experiences, aesthetic properties, and attractive and unattractive parameters. This paper presents the basic elements of western music aesthetics, especially big band jazz music, and how Salamander Big Band can implement the aesthetic values of western jazz big band music in the music played. This research uses a qualitative approach with a descriptive analysis method. Through a process of appreciation, habituation, additional insight into jazz music and continuous and consistent practice, Salamander Big Band members can adapt to cultures from outside Indonesia's popular music culture, namely playing American big band music with the right aesthetic.</p>

The History of Jazz

The History of Jazz, 3rd edition, is a comprehensive survey of jazz music from its origins until the current day. The book is designed for general readers and students, as well as those with more specialized interest in jazz and music history. It provides detailed biographical information and an overview of the musical contributions of the key innovators in development of jazz, including Louis Armstrong, Duke Ellington, Billie Holiday, Coleman Hawkins, Charlie Parker, Dizzy Gillespie, Thelonious Monk, Ella Fitzgerald, Miles Davis, John Coltrane, Ornette Coleman, and others. The book also traces the evolution of jazz styles and includes in-depth accounts of ragtime, blues, New Orleans jazz, Chicago jazz, swing and big band music, bebop, hard bop, cool jazz, avant-garde, jazz-rock fusion, and other subgenres and developments. The volume also provides a cultural and socioeconomic contextualization of the music, dealing with the broader political and social environment that gave birth to the music and shaped its development—both in the United States and within a global setting.

Modern Jazz

The rise of modern jazz—or “bebop” as it was called—dramatically changed the landscape of the music in the 1940s, transforming the genre into a truly progressive and experimental idiom. But this came at a cost, marking a shift from jazz’s predominance as a popular music, and turning it into an art music addressing a much smaller audience. This chapter looks at the innovations of the leading bebop musicians, especially Charlie Parker, Dizzy Gillespie, and Thelonious Monk. Other artists addressed include Bud Powell, Lennie Tristano, Sarah Vaughan, and Dave Brubeck. The chapter concludes with an assessment of big band jazz during the post–World War II era, including the work of Woody Herman and Stan Kenton.
