探戈擁抱:胸骨與動態平衡投射



在阿根廷探戈的三大類型 (Milonguero、Salon與Nuevo)當中,就屬Milonguero Style的擁抱為最緊密的;但它主要不是靠雙手臂去擁抱對方,而是靠著神祕的「胸骨」作為雙人移動時溝通的主要訊號來源。

胸骨(sternum)長得什麼樣?我Google到下圖,加上一段文字讓大家可以摸摸看:



將手指頭從喉頭往下移動,你會摸到凹處,那是胸骨的起點,稱為胸骨柄。再往下移,也會有一凹處,即俗稱的心窩,那是胸骨的迄點,稱為胸骨角(又稱劍突),從胸骨柄到胸骨角的整根骨頭稱為胸骨體,胸骨即是前述的泛稱。

此外,在Steven老師的文章裡,也有提到胸骨的作用。Steven老師的詮釋,是基於他向其他阿根廷探戈老師,朋友,舞者的學習;另外他自己也有ballroom及武術的背景,因此可以把動作元素拆解分析給讀者(Steven老師的Tango舞蹈教師證,有附在他的網頁上)。

在此,茲摘錄他其中一段關於胸骨與動態平衡投射的文字:

動態平衡投射,意指將我們的中央重心(center of gravity)投射至想要去的方向,在腳步還沒踩出去之前,就將它投射到最遠處。這樣的投射,不論在線性動態(直線行走或側踏),旋轉式動態,及身軀扭轉分離時的動態,皆會用到。簡而言之,就是將胸骨投射到踩步前所想去的方向。Leader使用這個方式,將下一步的意念,在動作前就先傳導出去。這麼作的原因在於,Tango舞者是以彼此的胸骨週圍及肋骨二側,作為連結。這種連結能有效的移動舞者二人所重新結合的中央重心,它位於肚臍上方(二人的肚臍上方皆有自己原本的中央重心)。

胸骨的位置,必須越過自己的垂直面 (此垂直面與中央重心交會以利與舞伴結合)。因此,只有一個辦法能確實的將動作意念傳達給Follower:在實際踩步前,把胸骨向前推送至最遠。

如果Leader的胸骨,沒有向前推送至超過重心腳的大姆指,則Follower將無法接收到清楚的方向訊息,以及接下來要踩步的意念。如果傳達的訊息不清楚,則Leader也應該要避免使用手去拉或推Follower來補強自己想傳達的訊息,因為這麼作,只會讓自己養成用手帶領的壞習慣。要使用胸(chest),而不是使用手,來帶領Follower。



原文如下:

Projectional

Projectional dynamic balance means to project our center of gravity toward the intended direction to its maximum reaching position before any step. This could be either translational, rotational and spiral in nature. Simply put, project the sternum toward to the point just before falling forward in the line of the intended movement. This is how the leader transmit the intention of the next step before the step. The reason is that tango dancers connect at the vicinity of the the sternum and sides of the rib cage, which effectively move the combined center of gravity of the dancer above the belly button, where center of gravity resides individually. Since the sternum location needs to pass beyond the vertical plane which intersect the center of gravity to make the connection with the partner, the only way and surely to indicate the movement intention to the follower is to push the sternum to its maximum outermost reaching point before the actual step. If the sternum has not moved and passed beyond the big toe of the standing foot of the leader, the follower will not able to receive good unambiguous directional information and the intention of the upcoming step. Leader should never try to compensate one's ambiguous leading by pushing and pulling with the arms as this will only reinforce the bad habit of leading by the arms not by the chest.
