This describes the part of the Lady’s centre (pelvis-abdomen) in contact with the centre of the Man. As partially described in Posture above, the contact between Man and Lady will be very slight but very precise. THere are nine possible positions of the centre where the Hand Hold will not vary. These positions are described below. ここでは、男子のセンターと接触している女子のセンター（骨盤腹部）の部分について記載しています。 上記のポスチャーの章で部分的に説明したように、男子と女子の間の接触は非常にわずかであるが、非常に正確である。 これは、ハンドホールドが変化しないセンターの9つの可能な位置である。 これらの位置については、以下で説明する。
1. Closed Position (Right to Right)
This is the basic position, normary used to start each dance. In the cosed position, the right side of the Lady’s centre is in contact with ther right side of the Man’s centre. Therefore, the left side of the Man and Lady are not in contact and the shoulders and hips remain parallel.
Because this is the most important position, it is also detailed in Posture section.
1a. Outside Partner Position
This position is very similar to that of the Closed Position and in used when the forward-moving partner has to step outside with the right foot. If the step take in elevation, the difference from the Closed Position is very slight: both make as sright rotation to the right in order to create approx. 1/8 of a turn between the shoulders and hips, allowing the forward-moving partner’s foot and knee to move outside the partner.
If the step is taken in a lowering situation, the hips will also slide slightly to the side until the right thigh of the fon/vard-moving partner is beside the right thigh of the backward-moving partner. In this situation, only the right rib bones will remain in contact.
2. Promenade Position
The points of contact in this position are the right side of the Man and the left side of the Lady, creating a V shape. This position is used when both partners have to move forwards in the same direction (towards the open part of the V shape).
To describe this position in further detail, the following example can be taken into consideration: starting from a Closed Position, the Promenade Position can be obtained through a slight rotation of both dancers‘ bodies (leftward for Man and rightward for the Lady). The two bodies will turn with a “hinge-like” action with no sliding movement to take on the “V” shape”.
3. Fallaway Position
The points of contact in this position are the right side of the Man and the left side of the Lady, creating a V shape. This position is used when both partners have to move ; backwards in the same direction (towards the closed part of the V shape). ) It should be noted that the Fallaway Position is very similar to the Promenade Position.
