So lemme see if i understand you correctly.I'm running 12,13 and 16.I should start with my 16 in the key of "Here" in "Here comes the bride," and my 13 will be the,"comes the bride",then it goes from 16 to 12 with the,"all" being the 16 and then going to the 12 with,"dressed" then to the 13 in,"in white."
