Of Self And Circumstance: Music And Representation In The Works Of Rodrigo, Walter Aaron Clark

Soundboard Scholar

Though Joaquín Rodrigo (1901-99) is renowned for his guitar works, especially the Concierto de Aranjuez, less well known is the fact that his compositions embrace a wide variety of genres, styles, and media, from piano solos to art songs and from orchestral tone poems to film scores. This article proposes a novel way of organizing and comprehending the roughly 200 works in his catalogue. Rather than the standard method of organization by chronology or medium, it surveys his oeuvre through multiple lenses, including literary, folkloric, virtuosic, sacred, historical, theatrical and descriptive. Each of these categories represents the salient dimension …

Spanish Guitarists In Nineteenth-Century São Paulo, Flavia Prando

Soundboard Scholar

This article explores the presence and activities of guitarists in nineteenth-century São Paulo. Drawing on reviews written by the pianist Alexandre Levy in 1890, I analyze concerts by Martínez Toboso and Gil-Orozco, two Spanish guitarists whose duo seems to have been the first to perform formal concerts in São Paulo. I also investigate Gil-Orozco’s subsequent work in São Paulo, where he lived for seventeen years (1890–1907), playing an essential role in the guitar’s development in the city.

The Flight Of The Maiden: Representations Of Women And The Guitar In Brazilian Culture, Cláudia Araújo Garcia

Soundboard Scholar

This article examines the relationship between women and the guitar in the context of both Brazilian literary discourse and the instrument’s culture and history. To this end, I have sought out texts that illustrate intersections between women and the guitar from the perspective of both female and male authorship. We see that the guitar provides a vehicle for the woman’s voice in all its restlessness, violation, and libertarian desire; but equally, it enables the perpetuation of stereotypes linked to the mirroring of the guitar and the female body. In the absence of literary and historic records of the guitar in …

"For Andrés Segovia": Francisco De Lacerda’S Suite Goivos (1924), Pedro Rodrigues

Soundboard Scholar

Suite goivos by Francisco Lacerda (1869–1934) stands out not only as one of the first examples of symbolist literature for guitar but also as the first work written for guitar by a Portuguese non-guitarist composer. So far, however, it has remained in relative obscurity. In this article, I first explore the suite’s context and history: its origin in meetings and correspondence between Lacerda and the work’s dedicatee, Andrés Segovia; its place among new works commissioned by Segovia from non-guitarist composers; and available manuscript sources for the work. I then argue for the work’s importance as music, highlighting its innovative features, …

Rural Electrification Using Iliceto Shield Wire Scheme In Developing Countries: Tanzania Case Study, Heavenlight M Munisi, Santos Kihwele

Tanzania Journal of Science

Rural electrification rate in Tanzania is still very low despite the efforts made by the Rural Energy Agency (REA) in Tanzania. Rural electrification using medium voltage (MV) method has two major obstacles. First obstacle is high cost associated with the cost of extending the grid electricity to rural areas. Second obstacle is remoteness of the villages, which leads to high power loss during transmission. In lieu of economic extension of rural electrification areas, this paper proposes a low cost solution of Iliceto Shield Wire Scheme (ISWS). This technique involves insulating shield wires (SW) from high voltage (132-400 kV) transmission line …

Assessment Of Seasonal Variations In Forage Quality In Saanane Island National Park, Mwanza, Tanzania, George M. Sangu, Cuthbert L. Nahonyo

Tanzania Journal of Science

Seasonal variations in proteins, vitamin A, vitamin C, carbohydrates and minerals (Ca, Fe, Na, K and P) for seven most grazed and four most browsed plant species were assessed using laboratory analysis to determine what nutrient resources were available to grazers and browsers inhabiting the Saanane Island. The results indicated great seasonal variations in proteins, vitamin A, vitamin C and carbohydrates which were statistically significant with P < 0.01, F 3.444 at DF 5. Similarly, the minerals (Ca, Fe, Na, K and P) showed greater seasonal variations with K and P being higher during wet season, while Na and Fe were higher in dry season. The levels of proteins, vitamins, fibres and minerals were well above daily dietary requirements for grazers and browsers. These results suggested that both grazers and browsers were benefiting from seasonal differences in terms of available resources at disposal as animal health is regulated by levels of proteins and vitamins available in grazing and browsing materials.  Keywords: Forage Quality, Minerals, Protein Saanane, Seasonality, Vitamin
