Corno da tirarsi
The corno da tirarsi is a Baroque brass instrument. Johann Sebastian Bach wrote for the instrument when he was working in Leipzig, and it appears to have been played for him by Gottfried Reiche.
It has been stated that it appears in four Bach cantatas.
However, it is only called for in three cantatas by name, BWV 46, 162 and 67.
Its characteristics are debated, but it was most likely a horn that resembled the "Inventions" horn of the late 18th century: "a freely-moving, double tuning slide positioned diametrically across its circular body". It may also have been a slide trumpet.
