Quotes About Key signatures

I didn't understand key signatures or anything, you know. I'd say silly things at the top of a trumpet part like, 'Note, when you play B naturals, make the B naturals a half step lower because they sound funny if they're B naturals.' And some guy said: 'Idiot, just put a flat on the third line and it's a key signature, you know?'

To the eye, the key signatures of relative keys are identical. Minor key signatures are laid out on the staff just like major key signatures. The sharps and flats are in the same octave and same order. Only by analyzing the melody to locate the tonic can a key signature be visually identified as major or minor.
