  A double-bore woodwind instrument of the Italian Renaissance.

1953 Galpin Soc. Jrnl. vi. 99 As each instrument is two instruments in one, Zacconi's doppioni of the same epoch and locality leap to the mind. 1955 [see krummhorn n.]. 1964 S. Marcuse Mus. Instruments 150/2 As the doppione had a compass of a 9th, it was probably furnished with a double reed and wind cap and had a cylindrical bore. 1976 D. Munrow Instruments Middle Ages & Renaissance vi. 50/4 [Rainer Weber and J. H. Van der Meer] conclude that the two bores of the doppioni were alternatives, designed to be played separately. 1978 New Statesman 10 Nov. 622/2 Sordumes and Doppions are obsolete wind instruments described in Michael Praetorius' Syntagma Musicum of 1619... There is no German equivalent for the Italian Doppioni. 1982 B. Boydell Crumhorn & Other Renaissance Windcap Instruments x. 373 The Doppioni..appear to have been a late Italian Renaissance experiment in combining two instruments in one to give the player a choice of alternative ranges... The windcap principle was not an essential part of the design.
