voici un article intéressant du Maitre Susumu Sudo sur l'accord arbre-pot :
"""There are some basic rules about matching pots with trees. Pines stay in unglazed pots and decideous trees in glazed pots. Chokkan matches well with rectangular pots and bunjin with round pots. Details such as the outer ridge or the inner ridge, a band, two bands or no band, relies on the creater's sense, does it? I have found an interesting article from Kinbon in this matter. Let's see what a professional says, the second generation keido master, Susumu Sudo.
Which pot matches best this black pine moyogi? It might be none of those, but try to guess first.
Before looking at the answer, I will show you principle rules in Keido. Both trees and pots are divided into "shin, gyo, so". For trees themselves, conifers are shin. Decidious trees are gyo. Kusamono are so. For tree forms, strong ones such as chokkan and thick moyogi are shin body. More gentle forms than those like shakan and thin moyogi are gyo body. Light forms like bunjin, fukinagashi, kengai and yoseue are so body. Regarding pots, deimono like hshidei and udei are shin. Glazed pots are gyo and rough clay pots like nanban are so. For the shape, basically rectangular pots are shin. Oval, moppo, square pots are gyo. Circle pots are so. However, there are many other elements like edge, decorations, legs and so on, hence the shapes are not always divided into the above classfication.
Here are the answers.
1) The size and the shape match the tree well. If the pot did not have decorations, it would have matched well. However, unfortunately the double lines on the top and the bottom strengthen the straight lines of the pot and it does not match the elegance of the trunk. The pot looks a bit too rigid.
2) The pot looks a bit heavy at first sight. But the lines are shin and it even has a clear classy feeling. Hence, it is not mismatching the pot, yet it is a bit too deep.
3) The inside edge is too weak, not strong enough to serve the tree. The depth and the spread legs match the tree but the edge gives an unsuitable feeling.
4) It clearly does not match the tree. The oval gentleness brings a weak look. It looks unstable and it does not help to show the quality of the tree.
5) On contrary to the four, the pot is too masculine. The size and stability are great without questions. However ookuma and a frame have too much impact. It kills the elegance of the trees.
6) This also does not match the tree. Oval and sack shape weakens the class of shin.
7) The rather subdued outer ridge and the frame are well banced and the size is also good. But the outer crowd legs are too dominating against the tree.
8) Here is the original pot for this tree. The pot shape with the outer ridge matches the tree well. The size and the depth are also perfect."""
