How to line up the most special 7 people dance formation, and then how to change the formation?

There are only a few types of group dance formations, and it is not easy to overdo it, because the composition of group dance is the theme of action modeling flow

The formations are: one row, two rows, two rows, two rows, two rows, two rows, two rows, three rows, round, slanting rows, vertical rows

The changes in the formations are designed according to the requirements of the action.

Group dance can play a lot of things, staggered, interspersed, scattered, but the arrangement is designed according to the composition

I'll be more specific, for example, I want to line up a group dance, the content of which describes a school

Composition:

Overall action, backpack, interspersed with multiple rows of the theme of the line

Solo dance, diagonal rows, a person jumping from the end of the front, you can add skills

Interlacing, triangular rows, a person from the last to the front, you can add skills

Interlacing, triangular formation theme

Large form ending, flow and gather into the final large form or change into a line directly off the stage

The above is the composition of the group dance, but I guess it is possible that you just need a change of formation, such as street dance ah, it's actually similar and more simple group dance in order to express the theme of the dance ideas need to change the scene to meet the central idea but for the lyrics of the pop song, the scene changes to meet the central idea, but for the dance, it's not a big deal to change the theme of the dance. But for a pop song with lyrics, the lyrics are the centerpiece of the dance, so it doesn't matter what kind of formation, what kind of movement, as long as it's stuck to the beat, there's no problem. A group dance choreography can take a week or more, but a group dance to a backing pop song can take as little as 30 minutes.

Your question is too broad, so I'll be thorough, and I'll just pick and choose according to what you need.
