Greetings! I have some questions regarding measurements in order to discern more easily from a Cornet to Trumpet to Flugelhorn. This all started when I acquired a very used cornet, but now I am not sure what I have exactly. I noticed that cornets in general tend to have a 4 1/2 inch bell. This one looks like a cornet but has a 5 inch bell. I noticed that Flugelhorns run about a 6 or plus inch bell. But yet, when I read online there seems to be various ranges of bell sizes altogether. I also perceive (I do not own one - yet) that flugelhorns have more length to them??? Okay, with that being said, I would like to inquire, what are the obvious points to quickly discern between a Trumpet, Cornet, and Flugelhorn? Please pardon my ignorance, but suddenly I am not sure how to identify them anymore. I see so many of these instruments online now and so many different loops of brass tubing styled differently, I am getting confused. I do know that cornets and flugelhorns taper whereas the trumpet is more evenly tubed throughout, but now I am wondering about other features to take note of when identifying one from another online. For example, also, I see some cornets that have really long valves, where others are a bit shorter. Does this make a difference? Are there some cornets with a lot larger bells? And the same with the other two? What is it exactly that is key in separating each instrument? Thanks so very kindly. I am so very glad that this forum exists to help with these questions! Thank you in advance! Blessings to all of you!!!!!!!!!
