In his contribution about Sgambati for the New Grove, John Waterhouse attaches a worklist supposedly by the composer himself, with a completely different numbering system than that used by Schott, Sgambati's main publisher, eliminating unused or disowned opus numbers. Library of congress has started to put them in the uniform titles, and new editions after 2001 (e.g. his symphonies) use the new numbering.
Harmonium may be substituted for the organ only when the string orchestra is substituted by a quartet of solo strings (vn va vc db) (paraphrasing composer's emphasis.) The violin part is taken by the first and second violins of the string orchestra in unison when performed so.
