Eric Hobsbawm and the Significance of Jazz

ABSTRACT

This paper explores Eric Hobsbawm’s interest in Jazz, and argues that he helped popularise the music, gave it intellectual credibility and that his jazz writings are still relevant for jazz scholars and cultural historians. Jazz also influenced his view of history. Drawing on his recently catalogued private papers, it suggests Hobsbawm consistently argued for the historical significance of jazz, was flexible in the use of genre and subgenre and was aware of the role of the music business, and the way critics and writers helped shape the music’s meanings. The paper also argues that Hobsbawm wrote partly as fan, and that his penetrating analysis of jazz sometimes led him to undervalue other popular music forms.     

‘Let the People Sing’: J.B. Priestley and the Significance of Music

Abstract

In a writing life that spanned the 1910 to 1970s, J.B. Priestley engaged with a variety of subjects, across various literary forms, ranging from politics, popular culture and Englishness through to theories of time. However it has rarely been noted that he also wrote passionately and knowledgeably about music, with the latter playing an important role in key novels, plays and nonfiction. Priestley also promoted chamber festivals, wrote the libretto for an opera ‘The Olympians’, and even occasionally performed himself. Priestley’s writings on music fitted into his concerns about the rise of an Americanized mass order, and his mistrust of commericalized musical forms was shared by other critics of the time. However, Priestley’s work is more significant than a binary high/low low cultural validation of classical music/dismissal of more popular musical forms. He was often critical of jazz and ragtime, but more positive about popular music that was produced in, reflected, and empowered the individual and community. Priestley’s writings on music marked a genuine attempt at understanding the role of music in culture, and contributed to his democratic critique of the mass society.     

Prediction of maximal oxygen uptake in sedentary males from a perceptually regulated, sub-maximal graded exercise test

The purpose of this study was to assess the validity of predicting the maximal oxygen uptake (VO2(max)) of sedentary men from sub-maximal VO2 values obtained during a perceptually regulated exercise test. Thirteen healthy, sedentary males aged 29-52 years completed five graded exercise tests on a cycle ergometer. The first and fifth test involved a graded exercise test to determine VO2(max). The two maximal graded exercise tests were separated by three sub-maximal graded exercise tests, perceptually regulated at 3-min RPE intensities of 9, 11, 13, 15, and 17 on the Borg ratings of perceived exertion (RPE) scale, in that order. After confirmation that individual linear regression models provided the most appropriate fit to the data, the regression lines for the perceptual ranges 9-17, 9-15, and 11-17 were extrapolated to RPE 20 to predict VO2(max). There were no significant differences between VO2(max) values from the graded exercise tests (mean 43.9 ml x kg(-1) x min(-1), s = 6.3) and predicted VO2(max) values for the perceptual ranges 9-17 (40.7 ml x kg(-1) x min(-1), s = 2.2) and RPE 11-17 (42.5 ml x kg(-1) x min(-1), s = 2.3) across the three trials. The predicted VO2(max) from the perceptual range 9-15 was significantly lower (P < 0.05) (37.7 ml x kg(-1) x min(-1), s = 2.3). The intra-class correlation coefficients between actual and predicted VO2(max) for RPE 9-17 and RPE 11-17 across trials ranged from 0.80 to 0.87. Limits of agreement analysis on actual and predicted VO2 values (bias +/- 1.96 x S(diff)) were 3.4 ml x kg(-1) x min(-1) (+/- 10.7), 2.4 ml x kg(-1) x min(-1) (+/- 9.9), and 3.7 ml x kg(-1) x min(-1) (+/- 12.8) (trials 1, 2, and 3, respectively) of RPE range 9-17. Results suggest that a sub-maximal, perceptually guided graded exercise test provides acceptable estimates of VO2(max) in young to middle-aged sedentary males.
