² For details of the gestation, translation, and publication of the conducting essay, see Macdonald, ed., Berlioz's Orchestration Treatise, xxiii–xxv. As Macdonald and others have noted, there were precedents for Berlioz's work, although none as widely known: Ludwig Spohr published beat-patterns in his Violin-Schule (1831), and Ferdinand Gaβner (Hofmusikdirektor of the Baden Kapelle in Karlsruhe) included beating instructions, rehearsal strategies, and orchestral seating arrangements in his Dirigent und Ripienist (1844). In France, both François Fétis, in his Manuel des compositeurs, directeurs de musique, chefs d'orchestre & de musique militaire (1837), and Jean-Georges Kastner, in his Cours d'instrumentation (1839), offered advice to conductors on auditioning, tuning, rehearsing and organizing the orchestra.

⁸ François-Antoine Habeneck (1781–1849), Directeur géneral de la musique at the Opéra from 1821 and Chef d'orchestre of the Société des Concerts du Conservatoire from 1828, was among the key advocates of violin-leadership, and a long-time adversary of Berlioz's, exercising prodigious influence over French orchestral performance practice and music pedagogy. His approach was carried forward by virtually all later conductors of the Conservatoire orchestra, up to and including Édouard Deldevez (who held the post from 1873–1885), ensuring that violin-bow direction persisted in Paris well after the baton had triumphed in London and in the major German-speaking centres. See Hugh Macdonald, ‘The French Tradition’, in The Cambridge Companion to Conducting, 134–45, and Charlton, David, ‘A Maître d'orchestra … Conducts: New and Old Evidence on French Practice’, Early Music 21 (1993): 341–53CrossRefGoogle Scholar.

¹⁷ ‘Une touche en cuivre semblable à une touche de piano, adaptée au pupitre du chef et à peine effleurée par l'index de sa main gauche, lui permet de marquer au loin les principaux temps de la mesure, pendant qu'il dirige avec son bras droit les groupes les plus rapprochés. Grâce à cet appareil si simple et si ingénieux, une seule personne pourrait conduire à la fois quatre orchestres placés au sud, au nord, à l'est et à l'ouest, aux quatre extrémités de la terre … avec un irréprochable ensemble, et iraient parfaitement en mesure, comme si elles avaient sous les yeux le bâton du chef.’ Revue franco-italienne (15 November 1855), in an advance report announcing the musical programmes for November 15 and 16.

²⁵ Cartoons satirizing the ear-splitting effect of Berlioz's orchestra on French audiences are well known, but its impact on foreign visitors was apparently equally devastating. Another image by Cham titled ‘Les Arabes à Paris’ (Charivari, 18 January 1845) shows a group of Arab visitors at one of the composer's ‘monster concerts’, covering their ears in postures of noise-induced anguish. A similarly robed and turbaned figure, now bearing an instrument, appeared in Cham's later cartoon of Berlioz's ‘global’ orchestra (as we saw in Figure 2). Foreign bodies seem both subjugated by Berlioz's ensemble and, at the same time, productive of its clamorous, annihilating effects.

Nélia Dias also draws attention to metaphorical cross fertilization, noting that the French anthropologist Mathias Duval, writing in the 1880s, conflated not just organic and inorganic conceptions of electrical function, but also military metaphors, describing the brain as an army general receiving and transmitting orders across a system of nerves operating like a telegraphic network; see Dias, Nélia, ‘Exploring the Senses and Exploiting the Land: Railroads, Bodies and Measurement in Nineteenth-Century French Colonies’, in Material Powers: Cultural Studies, History, and the Material Turn, ed.

³⁰ References to electricity, both medical and metaphorical, weave through the composer's personal and critical writing of the 1820s and 1830s. That his interest in the subject began early is confirmed in the Mémoires, where he makes reference to ‘a course on experimental electricity’, with the chemist Joseph Louis Gay-Lussac undertaken during his student days. See Berlioz, Hector, Mémoires, ed. Citron, Pierre (Paris: Garnier-Flammarion, 1969): 64Google Scholar.

³¹ ‘le publique arrive, l'heure sonne; exténué, abîmé de fatigues de corps et d'esprit, le compositeur se présente au pupitre-chef, se soutenant à peine, incertain, éteint, dégoûté, jusqu'au moment où les applaudissements de l'auditoire, la verve des exécutants, l'amour qu'il a pour son oeuvre le transforment tout à coup en machine électrique, d'où s’élancent invisibles, mais réelles, de foudroyantes irradiations. Et la compensation commence. Ah! c'est alors, j'en conviens, que l'auteur-directeur vit d'une vie aux virtuoses inconnue! Avec quelle joie furieuse il s'abandonne au bonheur de jouer de l'orchestre! Comme il presse, comme il embrasse, comme il étreint cet immense et fougueux instrument!’ Berlioz, Mémoires, ed. Citron, Vol. II: 78.

³³ Newton's notion of an ethereal fluid vibrating through solid nerve fibres is fleshed out in the second edition of his Optics (1717).
