Nope, but the basic range of most people will fall WITHIN the staff. Nothing too high, and nothing too low.
Different songs will be in different keys depending on the placement of the notes within the melody, so you can't just assume that ..... "so and so" sings in "G". That's not always the case. Try to keep the highest notes below the top note on the staff ( E or F )and most people will be comfy with that.
