A pirouette, no matter the type, only requires one preparation. Its common for some dancers to do the steps, leading into the preparation, then do a double bounce, or lifting a back foot into a smaller (or larger) fourth position before releveing and turning. This is common in, for example, a well-known preparation of “Tombe pas de bourre fourth position, pirouette.”
A dancer doing a double preparation will get to the fourth position, then make another adjustment into another fourth position and then try to turn. This habit makes your dancing appear less fluid and confident. Try the same preparation, but the fourth position you end in after the pas de bourre is the same fourth position that works for you to do a pirouette. Taking out a double preparation will add more clarity to your dancing and get your sooner on the track to improving pirouettes!
