The following is a common sequence of combinations in basic ballet training:

1. Warm-up combination: including squats, floor scrubs, small kicks and other movements, designed to warm up and stretch muscle.

2. Basic combination: including battement tendu, plie, battement tendu five-position mopping, battement tendu jete small kick, rond de jambe circle and other movements, which are the basic movements in basic ballet training.

3. Complex combinations: including various rotations, jumps, changes of direction and other movements. These movements are difficult and require certain skills and physical strength.

4. Coordination combination: including music coordination, rhythm changes, direction changes and other movements, aiming to cultivate the dancer's coordination and flexibility.

5. Expressive combination: including emotional expression, musical feeling and other movements. These movements require dancers to have good performance ability and artistic accomplishment.

The above combination sequence is not static and can be adjusted and combined according to the training purpose and actual situation. At the same time, different ballet schools and teachers may also have different combinations and sequences.
