追加保证金；征收保证金的要求

　　美股 Margin Call 的意思是补充保证金通知，增收保证金的意思。　　保证金是指在法律对于保证金缺乏明确规范的背景下，探讨保证金的类型，对于备用金类型的保证金、预付款类型的保证金、租赁保证金、装修保证金、定金类型的保证金、保有返还请求权的保证金、无双倍返还效力的保证金分别界定。保证金是指用于核算存入银行等金融机构各种保证金性质的存款。　　保证金也指合同当事人一方或双方为保证合同的履行，而留存于对方或提存于第三人的金钱。在现实经济生活中流行的保证金主要有两种形式：一种是合同当事人为保证其债权的实现而要求另一方提供的保证金。如建筑施工合同中，建设方在工程结算时依工程保修条款的约定将应付的部分工程款留作保修金，用来保证施工方保修义务的履行；如出现工程质量问题而施工方不予修理，建设方可使用保修金自行修理或请第三人修理。另一种形式的保证金，是双方在合同成立时候，为保证各自义务的履行而向共同认可的第三人（通常为公证机关）提存的保证金。而任何一方在其合同义务全部履行前均不得取走保证金。如一方违约，另一方可从保证金中获得违约金或赔偿金。

证券交易中追加保证金的行为，主要是针对期权(option)的卖方和期货(futuer)的买卖双方.因为上述交易，是有杠杆的，交易时只需要交纳一定的初始保证金（margin), 随后采用逐日盯市（mark to market) 每日结算。当日如果所持有的期货是盈利的，则不需要追加，当所持有的期货价值下降，亏损达到一定的幅度，则需要追加保证金（margin），使得保证金水平达到初始水平， 这种行为就叫margin call.

【答案】：追加保证金通知，又被称为变动保证金通知，是指在期货或股票市场上，由于市场价格朝着不利客户的方向变化，而使得客户的保证金余额低于维持保证金(maintenance margin)水平时，经纪人向该客户发出的要求追求保证金的通知；或者指由于市场价格朝着不利于结算会员的方向变化，而使得结算会员的初使保证金出现亏损情况时，结算所向该结算会员发出的要求补足保证金的通知。一般来说，客户或者结算会员在收到追加保证金通知之后，应于第二交易日开盘之前补足经纪人或结算所所要求的保证金。

有关次贷危机的三部电影之一——Margin call(译:利益风暴) 利益风暴是从一家投资银行的微观角度来演绎次贷危机爆发前夜，据说这家投资银行的原型就是雷曼兄弟，次贷危机中第一家倒下的华尔街老牌投行，剧情紧凑气氛紧张，从细节把危机展现的淋漓尽致！这个电影给我印象最深刻的就是沙利文坐在车里看着车窗外马路上熙熙攘攘的行人说的那句:“看看这些人，四处闲逛，对于将要发生的事一无所知”，其次就是银行大boss陶德那句:“在这一行谋生三个手段，动作快、智商高或者会骗人”。 中国股市中大部分散户就是“这些人”，他们没有消息渠道、没有交易技巧、没有止损意识，对市场趋势只能靠猜靠感觉，而中国股市偏偏是最不讲趋势的到处埋坑，当市场走势跟自己的预判和感觉不一样时，不采取措施总是想碰运气，最后只能在“对将要发生的事一无所知”下被一茬又一茬的割韭菜！ 所以，中国股市的大部分人都很难赚钱，我也是其中之一深有体会: 2009年我在深圳罗湖金光华广场一个香港公司做美股优先股daytrader，之所以是美国优先股而不是美股普通股，因为我们水平不够跟华尔街的那些交易员拼，只能交易一下交易频率低量小的优先股尽量降低风险以达到训练的目的。当时一个老师，算是一个老牌交易员，给我们上课讲的第一点就是“stop loss”，不懂的stop loss就不要进场。后来转投中国股市，我懵懵不知，总想着没交易一支股票不能超过预定止损点，因为T+1，隔日行情变动太大，止损点容易被跳过，导致最后交易失去理智完全不讲规则，亏损就死扛，期望着反弹到止损点再处理亏损股票，最终在15年下半年股灾中不想看交易账户，至今亏损60%。 想跟广大普通投资者分享的就像Margin call中演绎的: 我们普通投资者，没有资源、渠道去提前获知很多信息，对明天将要发生的一无所知，我们能做的就是“动作快”，及时止损！ 再者中国股市不是价值投资的场所，没有股票具有价值投资的意义，包括贵州茅台！这是由现阶段，不成熟的股市机制+不成熟的市场参与者共同导致的！

可以说《商海通牒》是时下最为应景的好莱坞电影，这个评价恰如其分。与很多拍摄华尔街电影不同的是，这部影片给我的感觉就是犀利，情节明快，剧情并没有拖泥带水，这种对于剧情的把控与金融危机背景之下，华尔街投行气氛相得益彰！我想这得益于导演J·C·陈多尔的敏锐的行业洞察力，虽然J·C·陈多尔并不是金融科班出身，但是从他的自述上来看，他的父亲曾是美林公司的员工，耳濡目染之下，想必他对金融行业的了解程度，比单从书本上得来的知识，更为贴近当下的环境。而家庭的背景，使他更能从人性角度来探讨投行员工的生存现状，工作的心理状态。他深入浅出的将这个24小时的金融惊魂，犀利的为我们铺展开一幅画卷。我们无需拥有更多的金融知识，一样能够读懂影片，这相比去年的《华尔街2》来说，《商海通牒》一个优势所在！我相信这部影片无疑会成为金融题材电影的未来的发展以及走势的一个成功例子。个人感言J·C·陈多尔对于其《商海通牒》的塑造是相当成功的！当然影片的大腕云集也提高了影片的知名度和影迷的期望程度，影片包括了凯文·斯派西、保罗·贝坦尼、杰瑞米·艾恩斯、斯坦利·图齐、黛米·摩尔、扎克瑞·昆图 、西蒙·贝克等在内的诸位实力派明星，但是明星的云集并非一种简单的堆砌，我们很高兴看到了J·C·陈多尔将这些大腕凝成了一股绳，当然这离不开大腕们充分的发挥了自己的特点，他们饰演了自己最为合适的角色，以及清楚的了解自己的角色定位，加上自己丰富的演绎经验，充分解读了导演的意图，自然的发挥，让100分钟的影片，看过依然意犹未尽！ 如果说去年的《金钱永不眠》是一部纯粹的金融电影。那《商海通牒》无疑更侧重于在金融危机下，在金钱诱惑之下，人性心理状态的描写以及残酷的竞争和无情。尽管手法赤裸，但是正是因为这种不加修饰的表现手法，才能最为直观的揭露了华尔街投行的“行业规则”，以及人人自危的生存状态。或许对于那些华尔街高层来说，他们本无意如此，但是在利益至上的社会背景之下，这或许是一种无奈。“弱肉强食”永远是不变的生存法则，也许这个法则或是残酷，但是我们不得不承认它带给了我们某种内在的平衡！这也就是资本主义社会即使经历了数次金融危机之后，依然屹立不倒的重要原因！在危机面前，道德只是炮灰，这就是我们的本罪！

金融衍生产品具有以下几个特点:1.零和博弈.即合约交易的双方(在标准化合约中由于可以交易是不确定的)盈亏完全负相关,并且净损益为零,因此称零和.2.高杠杆性.衍生产品的交易采用保证金(margin)制度.即交易所需的最低资金只需满足基础资产价值的某个百分比.保证金可以分为初始保证金(initial margin),维持保证金(maintains margin),并且在交易所交易时采取盯市(marking to market)制度,如果交易过程中的保证金比例低于维持保证金比例,那么将收到追加保证金通知(margin call),如果投资者没有及时追加保证金,其将被强行平仓.可见,衍生品交易具有高风险高收益的特点.金融衍生产品的作用有规避风险,价格发现,它是对冲资产风险的好方法.但是,任何事情有好的一面也有坏的一面,风险规避了一定是有人去承担了,衍生产品的高杠杆性就是将巨大的风险转移给了愿意承担的人手中,这类交易者称为投机者(speculator),而规避风险的一方称为套期保值者(hedger),另外一类交易者被称为套利者(arbitrager)这三类交易者共同维护了金融衍生产品市场上述功能的发挥.从金融衍生品的种类和定义来看，其最大特征是依托一种投资机制来规避资金运作的风险，同时又具有在金融市场上炒作交易、吸引投资者的功能。金融衍生产品交易不当将导致巨大的风险,有的甚至是灾难性的,国外的有巴林银行事件,宝洁事件,LTCM事件,信孚银行,国内的有国储铜事件,中航油事件.

金融衍生品(derivatives)，是指一种基于基础金融工具的金融合约，其价值取决于一种或多种基础资产或指数，合约的基本种类包括远期合约、期货、掉期(互换)和期权。金融衍生品还包括具有远期、期货、掉期(互换)和期权中一种或多种特征的混合金融工具。拓展资料：这种合约可以是标准化的，也可以是非标准化的。标准化合约是指其标的物(基础资产)的交易价格、交易时间、资产特征、交易方式等都是事先标准化的，因此此类合约大多在交易所上市交易，如期货。非标准化合约是指以上各项由交易的双方自行约定，因此具有很强的灵活性，比如远期协议。金融衍生产品是与金融相关的派生物，通常是指从原生资产(英文为Underlying Assets)派生出来的金融工具。其共同特征是保证金交易，即只要支付一定比例的保证金就可进行全额交易，不需实际上的本金转移，合约的了结一般也采用现金差价结算的方式进行，只有在满期日以实物交割方式履约的合约才需要买方交足贷款。因此，金融衍生产品交易具有杠杆效应。保证金越低，杠杆效应越大，风险也就越大。金融衍生产品具有以下几个特点:1、零和博弈即合约交易的双方(在标准化合约中由于可以交易是不确定的)盈亏完全负相关，并且净损益为零，因此称"零和"。2、跨期性金融衍生工具是交易双方通过对利率、汇率、股价等因素变动的趋势的预测，约定在未来某一时间按一定的条件进行交易或选择是否交易的合约。无论是哪一种金融衍生工具，都会影响交易者在未来一段时间内或未来某时间上的现金流，跨期交易的特点十分突出。这就要求交易的双方对利率、汇率、股价等价格因素的未来变动趋势作出判断，而判断的准确与否直接决定了交易者的交易盈亏。3、联动性这里指金融衍生工具的价值与基础产品或基础变量紧密联系，规则变动。通常，金融衍生工具与基础变量相联系的支付特征有衍生工具合约所规定，其联动关系既可以是简单的线性关系，也可以表达为非线性函数或者分段函数。4、不确定性或高风险性金融衍生工具的交易后果取决于交易者对基础工具未来价格的预测和判断的准确程度。基础工具价格的变幻莫测决定了金融衍生工具交易盈亏的不稳定性，这是金融衍生工具具有高风险的重要诱因。5、高杠杆性衍生产品的交易采用保证金(margin)制度.即交易所需的最低资金只需满足基础资产价值的某个百分比.保证金可以分为初始保证金(initial margin)，维持保证金(maintains margin)，并且在交易所交易时采取盯市(marking to market)制度，如果交易过程中的保证金比例低于维持保证金比例，那么将收到追加保证金通知(margin call)，如果投资者没有及时追加保证金，其将被强行平仓.可见，衍生品交易具有高风险高收益的特点.6、契约性金融衍生产品交易是对基础工具在未来某种条件下的权利和义务的处理，从法律上理解是合同，是一种建立在高度发达的社会信用基础上的经济合同关系。7、交易对象的虚拟性金融衍生产品合约交易的对象是对基础金融工具在未来各种条件下处置的权利和义务，如期权的买权或卖权、互换的债务交换义务等，构成所谓"产品"，表现出一定的虚拟性。8、交易目的的多重性金融衍生产品交易通常有套期保值、投机、套利和资产负债管理等四大目的。其交易的主要目的并不在于所涉及的基础金融商品所有权的转移，而在于转移与该金融商品相关的价值变化的风险或通过风险投资获取经济利益。此外，金融衍生产品还具有未来性、表外性和射幸性等特点

交易部位、头寸(POSITION)是一种市场约定，承诺买卖外汇合约的最初部位，买进外汇合约者是多头，处于盼涨部位；卖出外汇合约为空头，处于盼跌部位。空头、卖空、作空(SHORT)交易预期未来外汇交易的价格将下跌，即按目前市场价格卖出一定数量的货币或期权合约，等价格下跌后再补进以了结头寸，从而获取高价卖出、低价买进的差额利润，这种方式属于先卖后买的交易方式。多头、买入、作多(LONG)交易者预期未来外汇市场价格将上涨，以目前的价格买进一定数量的货币，待一段时汇率上涨后，以较高价格对冲所持合约部位，从而赚取利润。这种方式属于先买后卖交易方式，正好与空头相反。平仓、对冲 (Liquidation)通过卖出（买进）相同的货币来了结先前所买进（卖出） 的货币。揸：买入（源自粤语）沽：卖出（源自粤语）波幅：货币在一天之中振荡的幅度窄幅：30～50点的波动区间：货币在一段时间内上下波动的幅度部位：价位坐标上档、下档：价位目标．（价位上方称为阻力位，价位下方称为支撑位）底部：下档重要的支撑位长期：一个月～半年以上（200点以上）中期：一星期～一个月（100点）短期：一天～一星期（30～50点）单边市：约有10天半个月行情只上不下、只下不上熊市：长期单边向下牛市：长期单边向上上落市：货币在一区间内来回、上下波动牛皮市：行情波幅狭小消耗上升：上升慢，下降快上扬、下挫：货币价值因消息或其它因素有突破性的发展胶着：盘势不明，区间狭小盘整：一段升（跌）后在区间内整理、波动回档、反弹：在价位波动的大趋势中，中间出现的反向行情打底、筑底：当价位下跌到某一地点，一段时间波动不大，区间缩小（如箱型整理）破位：突破支撑或阻力位（一般需突破20～30点以上）假破：突然突破支撑或阻力位，但立刻回头作收：收盘上探、下探：测试价位获利了结：平仓获利恐慌性抛售：听到某种消息就平仓，不管价位好坏停损、止损：方向错误，在某价位立刻平仓认赔空头回补：原本是揸市市场，因消息或数据而走沽市．（沽入市或沽平仓）多头回补：市场原走沽市，后改走揸市．（揸入市或揸平仓）单日转向：本来走沽（揸）市，但下午又往揸（沽）市走，且超过开盘价卖压：逢高点的卖单买气：逢底价的买单止蚀买盘：作空头方向于外汇市场卖完后，汇率不跌反涨，逼得空头不得不强补买回。

商业银行、公正领域、证券领域、数字货币、保险领域、审计领域都有广泛的应用

向你的broker借的，也就是债券交易的经纪人，比如国内的证券公司，当然借你会需要一定的担保，这个保证金叫做margin，如果你卖空之后价格上涨了，你会出现亏损，当亏到一定程度时会有一个margincall，就是会叫你追加保证金，如果不能追加，你的经纪人会强行给你平仓以确保你的亏损不会超过你的保证金，因为超过保证金的话经纪人就有亏损的可能了。

回复：开户金是开户时最低入金要求，如某些公司需要最低入金1万美元。投资组合保证金账户是一种账户类型。-------------------------------------美股开户时选择的现金账户与保证金账户有什么不一样?美股开户的时候有选择账户的步骤，好像不同的平台都是有选这两个之一的，它们有什么区别？牟树兆现金账户是最简单的账户，不允许透支，不允许卖空股票，有些券商甚至不允许现金账户买卖期权或仅允许风险低的期权组合(如Covered Call)。现金账户实行T+3，在5个交易日内买卖同一只股票的次数不能超过3次，否则会被冻结账户90天。现金账户开户最低资金要求较低，有些券商可以低至$500（甚至有0的）。 保证金账户顾名思义可以向券商融资炒股，此外保证金账户还能自由地开展期权交易，现金账户实行T+0交易制度。不过资金要达到$2000以上，有期权交易需要的就得用保证金账户。2013-12-05 12:35:21用户追问(0) 评论(0)反对(0)推荐(0)想飞的鱼证券账户是用来投资股票，基金的 保证金账户是在投资期货的时候开设的其中一个账户2013-12-05 13:03:13用户追问(0) 评论(0)反对(0)推荐(0)扬子鳄保证金账户（margin account）也称透支账户，信用账户。通过该账户，投资者可以用股票作抵押，按账户资产总市值的一定比例借用证券公司资金进行投资。如果市场出现下跌，股票市值达不到抵押的最低标准，投资者必须追加保证金或抛售股票。在美国透支账户由联邦政府法规管辖；联邦储备局对透支比例做出特别规定。

建议你去论坛找一下，或者是到下面的地址免费获取

一、地址解析地址解析，是用户输入一个详细到门牌号的地址。例如“北京市中关村南大街27号中央民族大学”，那么地址解析接口，会返回一个经纬度Point。接口定义如下：getPoint(address:String, callback:Function, city:String)对指定的地址进行解析。如果地址定位成功，则以地址所在的坐标点Point为参数调用回调函数。否则，回调函数的参数为null。city为地址所在的城市名，例如“北京市”。代码示例：// 创建地址解析器实例var myGeo = new BMap.Geocoder();// 将地址解析结果显示在地图上,并调整地图视野myGeo.getPoint("北京市海淀区上地10街", function(point){if (point) {map.centerAndZoom(point, 16);map.addOverlay(new BMap.Marker(point));}}, "北京市");运行该示例，请点击：http://openapi.baidu.com/map/examples.html?v=1.1&7_12#7&12 二、反地址解析反地址解析，就是传进去一个经纬度Point，它会返回一个详细的地址。具体地址有多详细，就要看百度数据库里的数据了。接口定义如下：getLocation(point:Point, callback:function[, options:LocationOptions])对指定的坐标点进行反向地址解析。如果解析成功，则回调函数的参数为GeocoderResult对象，否则回调函数的参数为null。代码示例：var gc = new BMap.Geocoder(); map.addEventListener("click", function(e){ var pt = e.point;gc.getLocation(pt, function(rs){var addComp = rs.addressComponents;alert(addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street + ", " + addComp.streetNumber);}); });运行该示例，请点击：http://openapi.baidu.com/map/examples.html?v=1.1&7_15#7&15三、同时运用地址解析与反地址解析在什么情况下需要同时运用这两个接口呢？答案是，当你搜索一个模糊的地址，但却想要返回一个精确的地址结果。例如“上海市新华路”，但是你想知道“新华路”在哪个区县的时候，你就可以同时利用这两个接口。完整HTML代码：<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>地址解析+反地址解析</title><script type="text/javascript" src="http://api.map.baidu.com/api?v=1.2"></script></head><body><div style="width:520px;height:340px;border:1px solid gray" id="container"></div><div style="margin:10px 0;"><input type="text" style="width:300px;margin-right:10px;" value="新华路" id="searchValue" /><input type="button" value="搜索" onclick="search()" /></div></body></html><script type="text/javascript">var map = new BMap.Map("container");map.centerAndZoom(new BMap.Point(121.461165,31.234095), 11);function search(){var myAddress = document.getElementById("searchValue").value;var myGeo = new BMap.Geocoder();myGeo.getPoint(myAddress, function(point){ //我输入的是“知春路”，第一步getPoint是地址解析。if (point) {map.centerAndZoom(point, 16);map.addOverlay(new BMap.Marker(point));myGeo.getLocation(point, function(rs){ //这里弹出“知春路”的详细地址信息，第二步getLocation是反地址解析。var addComp = rs.addressComponents;alert(myAddress+"的具体位置是："+addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street + ", " + addComp.streetNumber);});}}, "上海市"); //必须设置城市}</script>

Thanks for EverythingMy wife, Shirley, and I have gone on vacations to a quiet beach in southwestern Florida for most of our married life. If that beach could talk, it would tell of teenage newlyweds who sunned and wrote "I love you" on its sands. It would tell of a little girl with eyes the color of the sea gathering seashells and of three wild boys leaping and diving into the surf. It would tell of joyous visits over the years from friends, parents, grandparents, new brides and grooms -- and now grandchildren. The beach would tell glorious tales of warmth and gratitude. But I realized one day that I had rarely expressed my gratitude to the one who‘d lived those years with me. On our 40th wedding anniversary, Shirley and I walked again the familiar margin of the sea. I told her then how thankful I was that she shared my life.We don‘t have to wait for anniversaries to thank the ones closest to us -- the ones so easily overlooked. If I have learned anything about giving thanks, it is this: Give it now! While your feeling of appreciation is alive and sincere, act on it. Saying thanks is such an easy way to add to the world‘s happiness.A few years ago, a young woman from a neighboring town won a scholarship to a prestigious college. Although the inner-city high school she attended was plagued with problems, she overcame them and excelled. When she graduated, she commended the often-maligned school for its challenging courses and her teachers for their special interest and encouragement. "I can‘t say enough good things about the school and the teachers who gave me so much of themselves," she said. "I shall be eternally grateful to them."Saying thanks not only brightens someone else‘s world, it brightens yours. If you‘re feeling left out, unloved or unappreciated, try reaching out to others. It may be just the medicine you need.Before A. J. Cronin became a bestselling author, he was a doctor. Once he told about a colleague who gave an unusual prescription to patients afflicted with worry, fear, discouragement or self-doubt. The doctor called it his thank-you cure. "For six weeks I want you to say thank you whenever anyone does you a favor. And to show you mean it, emphasize the words with a smile." Within six weeks most of the doctor‘s patients showed great improvement.Of course, there are times when you can‘t express gratitude immediately. In that case don‘t let embarrassment sink you into silence -- speak up the first time you have the chance.I recently returned home to Montpelier, Ohio, for a short visit. Memories of my boyhood flooded back as I walked the familiar streets. Then I saw Mrs. Bible, and my mind flashed back to high school.I was a freshman, more interested in sports than school work, and I was falling behind in my Latin class. Then Violet Bible, a neighbor who was a schoolteacher, found out about my problem. "Oh, Latin‘s great fun," she told me. "Come over tonight after dinner and I‘ll show you." For the next several weeks, she tutored me until I could conjugate with the best of them -- well, almost. Anyway, I passed. At the callow age of 14 it seemed perfectly natural to me that a working wife and mother had nothing better to do after a hard day‘s work than tutor me in Latin.Now as I saw her, I realized what an uncommon sacrifice it had been. And, after all those years, I told her so! "What you did was way beyond the call of duty," I said. "Thank you." I was rewarded with a surprised smile and a sparkle in her eyes.Each human being is yearning for kind words of appreciation. In December 1991, 17-year-old Candi Brown‘s car overturned; the roof collapsed and crushed her skull. The crews of Engine Company 8 and Med 15 in Grayson, Ga., rushed her to Gwinnett Medical Center. Doctors told her parents to prepare for the worst. But Candi survived. A year later the family served a holiday dinner to the Gwinnett County firefighters and emergency medical technicians. During dinner Candi, whose goal is to walk naturally again, rose painfully and said, "Thank you for helping God save my life and giving me a second chance. I love you.""It‘s rare that we receive this kind of thanks," fire department lieutenant Bobby McKinzie said. "We were glad to have a part in her life. Today she‘s definitely touched ours."Maybe we are so used to being served by professionals that we forget to thank the teacher, police officer, doctor, firefighter or preacher who goes out of the way to help us. Maybe we need to be more creative in showing our thanks.In the novel I Heard the Owl Call My Name, Margaret Craven tells of a young minister, Mark Brian, who is sent by his bishop to a remote parish of Kwakiutl Indians in British Columbia. The Indians, he is told, do not have a word for thank you. But Brian soon finds that these people have exceptional generosity. Instead of saying thanks, it is their custom to return every favor with a favor of their own, and every kindness with an equal or superior kindness. They do their thanks.I wonder if we had no word in our vocabulary for thank you, would we do a better job of communicating our gratitude? Would we be more responsive, more sensitive, more caring?As the Pilgrims of Plymouth Colony faced their second winter in 1621, they had much to be grateful for. Their efforts to raise barley and peas had been disappointing, and they would have faced starvation, but thanks to an Indian named Squanto, whom Gov. William Bradford called "a special instrument of God," they had harvested 20 acres of corn. Squanto had also helped the settlers keep peace with neighboring tribes.So when it was decided to celebrate the harvest and thank God, Governor Bradford sent a messenger to Chief Massasoit, inviting the Indians to whom they were so indebted.Massasoit brought 90 men with him, and they celebrated for three days. Squanto, who spoke English, helped the Indians and Pilgrims communicate, but food and drink were the language of their thanksgiving festivities. And they were enjoyed to the fullest.Thankfulness sets in motion a chain reaction that transforms people all around us -- including ourselves. For no one ever misunderstands the melody of a grateful heart. Its message is universal; its lyrics transcend all earthly barriers; its music touches the heavens.
