Music theory

Let us start from basic scales

scale["Major"] = {2,2,1,2,2,2,1};

makeScale[root_, scale_, pos_List] := With[{base = Accumulate[Join[{root}, scale]]},
  (base[[Mod[#-1, Length[base]-1] + 1]] + 12 Floor[# / Length[base]]) &/@ pos
]

Table[
  {SoundNote @ makeScale[1, scale["Major"], Table[  i + offset, {i, 1, 6, 2}] ], offset + 1}
, {offset, 0,6}];
