When you see a song its transposed to a key major or minor. Depending who wrote it and what key they used minor for a trumpet player could be major for a guitarist usualy its the opposite though. Another words just because the key signature says somthing it may not be in your key in wich case you need a capo. I hope that makes since too you it would be better if I knew if you know music theory and the cirlce of 5ths. Ask a music teacher about the 5ths thats hard to explaine as well!
