 The work was first published as "Opus 1, No.9" in 1730 in an unauthorised and "disgracefully botched" edition—in fact by John Walsh of London but with a forged title page claiming Jeanne Roger of Amsterdam as the publisher—in which it was transposed to B minor for flute from its original key of D minor, and with its third and fourth movements omitted.Both the Walsh editions and the Chrysander edition indicate that the work is for flute ("Traversa"), and published it as "Sonata IX".
