&amp;#039;&amp;#039;&amp;#039;81/80&amp;#039;&amp;#039;&amp;#039; 혹은 신토닉 콤마(Syntonic comma)는 피타고라스 장 3도([[81/64 (Korean)|81/64]])와 5-한계 순정률 장 3도([[5/4 (Korean)|5/4]])간의 오차로, [[5-한계]] 순정률에서 매우 중요한 음정이다.&lt;br /&gt;
피타고라스 음률의 장음계에서 6, 3, 7도를 신토닉 콤마만큼 내리면 5-한계 순정률에서 흔히 사용되는 장음계가 된다.&lt;br /&gt;

신토닉 콤마를 내림으로서 피타고라스 음률보다 분모, 분자가 간단해지는 장점이 있지만, 같은 장 2도가 [[9/8 (Korean)|9/8]]와 [[10/9 (Korean)|10/9]]으로 나뉘어지는 문제점이 생긴다. 이로 인해 진행 도중 조성을 바꾸면 일부 음이 신토닉 콤마만큼 어긋나 불협화음이 생기게 된다. 대표적으로 늑대 4도([[27/20 (Korean)|27/20]])와 늑대 5도([[40/27 (Korean)|40/27]])가 있다.&lt;br /&gt;
