Just wondering whether anyone else finds that the instrument being used affects the mouthpiece preference? Or am I just imagining the difference because I'm still getting used to the instrument? I've recently got a new soprano cornet and have stuck with the same mouthpiece I had been using before (DW S). I used to really like it, but it just doesn't feel quite right now. I had considered trying out some different ones when I bought my new soprano, but figured it would be best to get used to it first so that I could tell whether it was the instrument or mouthpiece making the difference. Bizarrely I tried out a 7C mouthpiece yesterday that I used to hate, and now quite liked the feel of it - although not the sound. Any advice?
