The horn is hanging at a chain attached to the ring soldered onto a copper band that embraces the instrument, the white mouthpiece can be of bone or ivory, the other end is wrapped in a sort of "bell" of brass.
Of the shawm (?) is visible only the central part of the pipe put askew under the horn.
The hurdy-gurdy, large format, played by the putto has the trapezoidal body with a widening with two beack in the sides of the wheel, covered by the wheel cover;on the soundboard there are three perforated rosettes; you can see the crank but are not visible the keyboard and the pegbox. The 5 strings are tied to an untrusted bridge/tailpiece.
Among the foots of the putto you can see part of the body, of the neck and of sickle pegbox with the three pegs of a viola da braccio.
Two bells of trumpets protrude from the canopy on which puts feet the putto player.
