提高合唱指挥舞台表演的几点思考

合唱指挥表演者如何展示舞台表演风格、表演水平和自身风采，是合唱指挥表演者综合音乐素质和表演技术的具体体现。它不是靠单方面的知识就能完成的多元艺术。就是一位成熟的合唱指挥，也往往因一时找不到投入的表演感觉而严重影响了合唱指挥的舞台表演质量。那么，怎样才能比较完美的展现合唱指挥舞台表演能力和水平呢？笔者谈如下几方面感受供合唱指挥表演者和合唱指挥教学者共同探讨和研究。     

合唱指挥技法对合唱团员情感激发的影响探讨

合唱指挥的技术在很大程度上，影响合唱团员的现场发挥，指挥者的衣着和内在要与合唱团的协调，这一方面很重要，指挥者要根据表演风格进行指挥，承担着重要的导演任务，要注意姿势和美观程度，该文主要介绍合唱指挥的指挥技法对合唱团员审美的影响。     

论合唱指挥应具备的素质

合唱指挥是集音乐理论知识与音乐表演技能于一身的职业，是音乐专业中的复合型人才。本文就合唱指挥应具备的音乐理论基础、音乐感知能力、音乐技能、文化素养、组织能力、音乐感染力和人格魅力等六个方面的基本素质进行了论述。     

论合唱指挥教学中基本姿势的放松与紧张关系

在高师师范专业的教学中,合唱指挥课是一门必修课,但如何能够使学生掌握和学好这门课,并使学生掌握最基本的合唱指挥姿势,使其正确理解合唱指挥基本姿势放松与紧张的原则是一个重要的问题。     

如何做好合唱指挥前的案头工作

合唱 ,是声乐艺术中的整体表现形式 .它是通过作曲家、合唱队员和指挥之间的相互配合而共同完成的 .其中指挥是作曲家与合唱队员及听众之间的桥梁 ,它通过各种指挥语言 ,组织指导合唱队揭示音乐作品的主题思想 ,表现音乐的情感内涵 .以《黄河船夫曲》为例 ,从作品的选择、了解、分析、处理及指挥动作的设计五个方面论述了指挥在排练之前 ,该如何认真、细致地做好案头工作 .     

浅谈合唱指挥应具备的基本素质

在合唱艺术大繁荣的今天,我们有越来越多的人在合唱艺术的舞台上表演着他们的精彩。但也有好多时候许多热爱合唱艺术的人还在为一些合唱指挥的技术问题而困惑,希望通过对合唱指挥应具备的素质的描述能够为他们提供帮助,并能让更多的人在合唱的舞台上表演得更精彩。     

浅论指挥技法对合唱团员审美的促进作用

指挥技巧的正确与否,手势表达情感的程度,都直接影响到合唱团员对乐曲的理解,影响到其审美体验。指挥技法的运用对提高合唱团员的审美有着决定性的作用。本文结合指挥技法与审美的关系去研究如何有效的提高和促进审美进行具体论述。     

合唱中指挥语言的艺术性塑造

新中国的成立和改革开放以来,中国的合唱艺术有了更为广阔的发展天地。现今,合唱艺术已成为高等院校课程设置和校园文化建设必不可少的部分,合唱在人们的生活中已成为一种情感的表达,也是生动展现人们内心感情的艺术形式。在合唱中指挥者引领着队员们完美展现合唱作品、传达作品情感、渲染观众,把合唱作品思想的真谛通过歌声传达到听众的内心。因此,探讨合唱中指挥语言的艺术性塑造具有实用性的价值意义。     

中学生合唱研究

合唱是声乐高级的集体表演艺术,是一门必不可少的课程。合唱教学在音乐教育中占有重要的位置。它对激发学生的学习兴趣,培养音乐感受力、表现力和审美能力,陶冶学生的集体主义情操都具有重要意义。本人在长期的中学音乐教育研究中认为,在合唱的排练和教学过程中,还包含着对演唱欲望、合唱技巧、合唱指挥以及对音乐作品的欣赏能力与表现能力的培养。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.
