The '''skeetsma''' is a [[7-limit]] [[unnoticeable comma]]. It is equal to the difference between the [[Pythagorean comma]] and the keema ([[875/864]]). This makes it a keemic schisma, and so a skeetsma. It is also equal to the difference between the schisma ([[32805/32768]]) and the ragisma ([[4375/4374]]).
