How to get better balance?

This is a matter of trial and error. First examine your posture in the passé relevé: Do you go up "locked and loaded" (no wishy-washy relevé, but as high as you can manage)? Are you pulled up out of your hips, or are you sinking into one or both? Head up, spine straight, arms correctly placed? Now you have to analyze the problem. Which direction do you fall? If it's forward or backward, adjust your back by about three degrees (i.e. too straight a back will allow you to fall backwards, so bring it forward and the reverse if you fall forward). If you fall to one side or the other. move your hips to compensate. You will just have to keep practicing and analyzing until finally you hit it right. You'll know when you get it-- it's like learning to ride a bicycle: the clouds roll back, the sun comes out and all the angels sing halleluiah! Do it a few more times to get it into muscle memory. It may take longer on one side than the other, but don't worry. It will come.

Honestly, I never had the best balance when I danced, but what helped me the most is to just practice over and over. Get into your pirouette prep. Look at your alignment. Are you turned out? Is your front leg too far away, or too close to you? Then pull up into your passe. Are your shoulders down? Hips aligned? Turned out? Are you pulling your passe as high as you can? When you pull up into passe, is your supporting leg/ankle coming straight up, or are you sickling as you go into releve? Are you flexing your core? Are you pushing yourself straight up, or are you pushing slightly forwards, backwards, or to the side? Once you have the technique perfect, just keep practicing. If you have access to a barre, definitely use that. You don't even necessarily have to go from your prep into releve. You could start in sous sous and then pull your leg up into passe, with your hand still on the barre, and then slowly let go of the barre and bring that arm to meet the other in front of you. Good luck!

engage all your muscles,

your knees are pulled up (they are flexed)?

is your back straight?

core (abs) are flexed and pulled up?

are you looking up not down?

is your passe right on your knee?

what are your arms doing? floppy? jacknife? ( anything but floppy)

are your shoulders up or relaxed? (they should be relaxed/ down but still engaged)

these are questions to ask youreself!

go to a full length mirror and try asking yourself these questions and correct yourself you should get balance in no time!
