This question may have been asked before but rather than trawl through all the possible threads I will just ask. If the sound an Alto Sax makes with what we call the "C" key depressed is actually an Eb why don't we call it Eb? I don't understand the need for Sax's and Trumpets and Clarinets to be in these weird tunings. For example a Tenor sax is only one step off "C" anyway (I think) so why not make it a little shorter or longer to bring it to "C" then all the keys would be correct. I am a complete novice at music theory and many many aspects of music absolutely baffle me. Such as Modes, my son has tried to explain and I've read books on the subject but I just can't grasp it at all. To me, if you are playing the notes of the "F" scale in a different order they are still "F" scale. I guess I'm just thick. And you said there were no stupid questions.
