The New York-Based composer and publisher Peter Weldon's New York City addresses from 1800 through 1808 are listed in Virginia Larkin Redway, Music Directory of Early New York City (New York: New York Public Library, 1941), p. 24. The linguistic lapses and corrections to the title as well as the music itself possibly suggest the work of an amateur copyist, though the present manuscript may indeed have been used towards a publication of the work. "During the Nineteenth century, American interest in Latin American political events stimulated a constant stream of sheet music publications. The two decades during which Latin America was most to the fore were of course the 1840's and the 1890's. However, as early as 1810 the New York-based Peter Weldon' published there a Brazilian Waltz for flute, clarinet, or violin and piano, welcoming King John VI of Portugal to the New World. In an article tracing musical relations between Brazil and the United States, Carleton Sprague Smith began with Weldon's waltz, the Portuguese title of which was Favorita Waltz Brazilense Para Piano Forte com Accompanhamento de Flauta Clarinete o Violin.  The engraving on Weldon's cover shows the royal disembarkation at Rio de Janeiro in January of 1808. According to Smith, a change from major to minor would infuse more Brazilian character into the perky waltz theme. Weldon's piano part glistens with brilliant sixteenth-note arpeggiated figuration in the treble supported by a close-position waltz bass....Whether in any true sense Brazilian or not, Weldon's music did catch the American public's fancy. Richard J. Wolfe listed ten further issues at New York, Boston, and Philadelphia, all presumably antedating 1825."
