The Formal Upright is perhaps the most difficult and yet most rewarding of the styles. It should have a straight trunk with good taper.
The first branch should be at about 1/3 of the total height. The distance between the branches should decrease as you get closer to the top of the tree.
To get reasonable trunk taper can be difficult. However by pruning the top back hard while allowing the bottom branches to grow on you can over the space of a few years induce reasonable taper.
Formal Uprights tend to be conifers.
