You can recognize the three meanings of 'Ballett' (ballet) from context. The art form is often used without an article ('Ballett tanzen' — to dance ballet). The performance usually appears with an article ('das Ballett ansehen' — to watch the ballet). The ensemble is often specified more closely with a genitive ('das Ballett der Oper' — the ballet company of the opera).
Meine Nichte lernt seit einem Jahr Ballett.
My niece has been learning ballet for a year.
When 'Ballett' (ballet) refers to the art form, it is often combined with the verbs 'lernen' (to learn), 'tanzen' (to dance), 'üben' (to practice), or colloquially also 'machen' (to do).
Er wollte schon immer professionell Ballett tanzen.
He always wanted to dance ballet professionally.
The phrase 'ins Ballett gehen' (to go to the ballet) almost always means that you attend a performance as an audience member. The destination of movement is expressed with 'in' + accusative.
Gehen wir am Freitag zusammen ins Ballett?
Shall we go to the ballet together on Friday?
idea / performance / introduction
'die Vorstellung' and 'das Ballett' can both fit an event on a stage. However, 'Vorstellung' is the general word for a performance or showing, for example in a theater, cinema, or circus. 'Ballett' refers either to the dance form itself or to a performance featuring this dance. Learners may confuse the words when talking about an evening at the theater. If the only important point is that something is being performed at a specific time, 'Vorstellung' fits. If it is specifically about classical stage dance, 'Ballett' is more precise.

Die Vorstellung beginnt heute Abend um acht Uhr.
