The Afroporteña press and Afro-Argentine’s thought in the late nineteenth century

The journalistic boom that occurred in Argentina from the second half of the nineteenth century saw the emergence of an active afroporteña press that defend the interests of the black community. This paper, in addition to reviewing the history of the Afro-Argentines newspapers, emphasizes the role played by the elite of African descent in the promotion of modernity among his brothers, while exploring the possible bases for an identity in the ideas spread.

Becoming a national composer: critical reception to c.1925

The centrality of Vaughan Williams to British music in the first half of the twentieth century is now a commonplace in musicology, but this has not always been so. Prior to 1914 Vaughan Williams was regarded by a number of British critics as a figure of considerable potential, but of less interest than composers like Granville Bantock, Cyril Scott, and Joseph Holbrooke: a reflection, in part, of the many different strands that existed in musical modernism in pre-war Britain, as well as scepticism that Vaughan Williams's engagement with English folksong offered anything original. In this chapter, I consider this inauspicious early period of Vaughan Williams reception, when even works considered seminal today like the Fantasia on a Theme by Thomas Tallis were received by some critics with bewilderment, and the changes that took place in the years after World War One after which Vaughan Williams became the leader of British musical modernism. I argue that Vaughan Williams's emergence reflects a change in attitude by British critics to modernism in general, to their approach to musical criticism, and to Vaughan Williams's musical language; in particular I note the distinction increasingly drawn by critics between folksong arrangements and a musical language derived from folksong.
