I used to play the horn in a community orchestra several years ago, but I haven’t played in a while. So a few days ago I took out my horn, and of course the valves had seized up. It took a while to get the valves moving again, and to even get a sound out was quite an effort. Have to build up the lip muscles again. So today I tried again, and was able to play some melodies again, mostly on the B horn. Also practicing long sustained notes. I hope to join an orchestra again in the near future.
