You also need to practice pirouettes in a safe place, clear of any sharp objects or obstacles. It’s always preferable to practice in a dance studio under supervision.
Place your toe into the notch at the top of the front of your knee, staying careful not to over-cross the foot on the leg. You should feel support under your thigh, when you’re positioned properly.
Make sure you have a strong plie prep but don’t stay in your preparation (plie) too long, because then you will lose the momentum, making it difficult to pirouette.
Hold the other arm out to the side, palm forward and slightly below the shoulder. Keep the elbow in front of your body.
Make sure, while turning, you keep your hips stacked under your shoulders, there should be no curve in your spine. This will ensure better balance.
Keep your supporting leg nice and straight, and don’t sickle your feet. Sickling means that you let your ankle slouch and you lose your balance. Also remember to spot, so you don’t get dizzy. Don’t try double or triple pirouettes if you can’t get a single down.
Stop and return to fourth position. Your feet should be placed in the same position they were when you started.
For the first few tries, only attempt a single pirouette to familiarize your body with the feeling and motion. It takes time to work up to a double, triple, or a quad. You may even want to start with only quarter/half turns. If you try doubles/triples right away you will be disappointed.
