I know I could google and read up on this, but I like to read different perspectives, experiences, and opinions.
I know that a cornet is conical and a trumpet cylindrical. Historically, the cornet is a band instrument and trumpet for everything else. (Orchestra, jazz, etc.) The cornet plays in the same range as trumpet.
What are the differences in tone and how it plays? Why aren't they played much any more? (Why do all the bands have trumpet players, not cornet?)
