||According to Wikipedia (mostly a Tony Rickard's contribution apparently?), the string quartet version is in fact a transcription by the composer of his Brass Quintet No.4 in A♭ major Op.8, written before the publication of the latter (because it was considered unplayable. However, the Wikipedia article has no references to back this statement up, and the programme notes to BIS-CD-613 (Sounds of St. Petersburg by the Stockholm Brass), written by Per Skans, states that in 1893 Ewald "was awarded a prize in a chamber music competition at which Rimsky-Korsakov was a jury member. . . . The work with which he won his prize was a string quartet which later appeared as the Brass Quintet No.4". The earliest publication of this quintet on WorldCat is a 1982 edition by TBQ Press, "arranged by Joseph Haddad". This gives perhaps more strength to the string quartet being the original.
