My orchestra is doing much less demanding stuff now than it used to and often it plays things that have no trumpet parts but multiple horn parts that we don't have the players for. I have dusted off my old horn and been doing some practising with the aim of playing one of the lower horn parts as necessary. I also thought it might open up some more playing opportunities like wind ensembles.
I wonder if anyone else is doing serious doubling and how it affects their trumpet playing in the long term. Until now I have only ever dabbled in horn a couple of times a year for my own enjoyment. I have only ever known two people who doubled trumpet and horn, one of whom is a professional horn player and teacher at the royal academy in London. I have emailed him for any advice about switching, but maybe someone here does this.
This is where I am up to with the horn, mainly concentrating on getting a nice tone and trying to play in tune. I don't think I will ever be up to fast runs or very loud playing, but as long as I am good enough for one of the lower horn parts I will be happy.
