Could this be the same Giovanni Martinenghi a letter from whom dated 1803 to "I.A.S." ("Lettera di Giovanni Martinenghi C. R. B. a monsieur I. A. S") exists, or is that at best a relative or perhaps not even that? Eric 20:54, 31 August 2011 (UTC) (though from books "Gio Martinenghi" published in 1801, he seems to have been a mineralogist. Could be both, of course, but still. More likely to be by "this" Martinenghi is an arrangement for piano of a "Marcia Reale" by Gabetti, arranged ca.1860 apparently, self-published(?) and an also-self-published- or at least, published by G. Martinenghi- perhaps as did Edward Walker in the US, he was his own publisher and published others also, which is a different sense of self-published!... - a polka op82 "Meneghin in Trabisonda : la maschera milanese" in the 1890s estimated... (copy in Zurich's central library) Earlier, another polka, "La notte di S. Giovanni a Solferino : polka per pianoforte" op.6 (poss. 1880s- that's a lot of op.nos. in 10 years, but I've seen much much faster) Ah. it seems he did publish operas and works by others in the 1860s etc according to Worldcat.org e.g. one by Tamburini. Interesting .)
(Also see Contributions to the Raccoglitore Musicale by Francesco Pagani for publications by Martinenghi, I see. :) Eric 21:06, 31 August 2011 (UTC)
