The midwinterhoorn is blown like a trumpet.
This instrument is still in use in the east of the Netherlands.
In the middle of the winter in these surroundings you  can hear the sound everywhere around you.
Every village has its own melody.

This double pipe is like an aulos, but you play the instrument like a pipe.
It has an external windway.
It is a meditative solo instrument, with many possibilities for expression.

The closed pipe is made as a sub-subcontrabass or subcontrabass.
A new development is the external windway without a cork.
