I guess I need to practise something called "spotting". It is described in detail at this
Apparently...
It takes practice and you have to go verrrry slowly at first to get the hang of it... but you will be rewarded by non-wobbly turns, balanced stops, and a better feeling in your stomach all around.
Dancing is best learned visually, so I strongly suggest asking your teacher to teach you how to spot your turns.
You know how if you get motion sick, you're supposed to look at a stationary point? That's the idea behind spotting. If you're looking at something stable, your body will feel stable.
Here's a basic way to practice it without worrying about turn technique:
1. Facing straight ahead, find something to fix your eyes on that is eye level or slightly above. This is your "spot". It may be a wall clock, poster, anything that isn't going to move.
2. Slowly start to turn your body, keeping your focus on the spot *and your head stationary*. At this point your body is turning under your head, almost as if your head is floating. Once your body has turned as far as it can without moving your head, turn a little more so that your eyes are looking sideways at the spot. You are looking over your shoulder.
3. Without moving your feet, and keeping your body as still as possible, turn your head to find the spot looking over the other shoulder. This is the opposite of what happened in step 2 - now your head is turning above your body!
4. Always focussing on the spot, complete the turn with your body.
So your body starts the turn, your head whips around to catch up and go ahead of it, and then your body catches up. Your eyes are on one spot except for when it turns so fast you don't have a chance to get dizzy.
Practise this slowly, stopping at each step to make sure there is full separation between the head and body turn. Do it in each direction. Once it starts feeling familiar, do it without stopping the (still slow) rotation.
Then, do it for the types of spins you do, and work it up faster and faster. While practicing alone, you'll have to find a suitable spot in the room. If you're doing partner dancing, often you'll be spotting on your partner's face.
The other way of avoiding dizziness while spinning only applies if you are not generating the spin or unable to spot without disturbing your position; that is, if you are spinning in a lift, or in a super-fast spin where the partner is really powering it and you are basically turning on the spot. In those cases, you have to learn to "blank out" and not see the room, just sense your own balance and then focus as soon as you exit the spin. Those are special circumstances though!
But I am afraid all that detail sounds a bit like this right now...
Maybe I just need shoes that will not put a brake on my spinning all the time...
Maybe intensive yoga is the answer.
I think that is a similar idea. I am getting there but my core balance is spotty. Maybe my core muscles are too light and I need to focus on getting them stronger.
I never knew there was this kind of spotting. I thought you meant spotting as in, "He spoted me doing a backflip by holding his arms under my back."
