The semioctile aspect (harmonic 16) belongs to the family of tense aspects, which derive from the division of the circle (360º) by the number 2, as the opposition (harmonic 2), the square (harmonic 4), and the semisquare or octile and sesquicuadrate or trioctile (harmonic 8).
However, among the multiple ways in which the number 16 can be decomposed, the one that best allows to understand its meaning is 2 * 8, because it shows the blockade of number 2 (opposition) with the alert states the number 8 (semisquare or octile and sesquicuadrate or trioctile), which allow to react quickly to blockages, so that the action flows frantically without stopping at anything.
Trines generate automatic processes, whose execution and speed improve progressively, but they need a lot of practice to reach the maximum degree. In addition, the trines are extremely resistant to modification, once the action is started, it is executed exactly in the way learned from beginning to end. In contrast, semioctiles do not need training and can be applied to unpredictable situations to adapt to (or generate) all kinds of obstacles as the action develops.

In the following video you can easily see the differences between number 8 and number 16: at the beginning, the child is still, but observant and alert, because he does not know what action the man is going to initiate (semisquare or octile), then he has to keep attentive and alert as he picks up the jacket from the ground, because he does not know at what point he will have to interrupt the task in progress to respond to the man's action (sesquiquadrate or trioctile); and in the end, a fast and frantic action develops between the man and the child (semioctile).
