This painting by Simone Martini (1312), shows a musician playing two recorders together, giving a possibility
of simultaneously playing a tune and a drone or simple accompaniment. The tune and accompaniment can even be passed from one
pipe to the other. Joining the two together makes them easier to play since they form a single rigid instrument.
