What is the purpose of most of the Ulster Scots music?

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.  

answer michelangelo; i believe this is correct, plz check first good luck;

the amount of fabric used and the collar fitting and sleeve lenghts are the two options, that to me, make the most sense.

hope it ,

happy homework/ sutdy/ exam!
