This is what Lisa makes when she needs a break from the heavy work of
making horns.
They are made from one piece of reed and have finger holes.
Each instrument is unique and the tuning is individual.
Due to the nature of reeds (they are extremely sensitive for humidity) it
may, however,
change both key and pitch from one day to the next.
It is possible to learn how to tune it, but I would not say
that it is easy.
