Orchestral horns were often made and played in pairs. This matched set has additional tubing placed between the mouthpiece and instrument. This tubing is called a crook and allowed the player to make the length of the horn longer and thus play in a different key. The player would need to manually change the crooks between songs or even during rests in the music if they music changed key.Two crook and coupler type. One of a pair coiled in opposite senses.
