学习古筝要先有浓厚的兴趣,兴趣是最好的教师,没有兴趣学什么都提不起精力,只会浪费时间。因而学古筝必定要本人发自内心的喜爱,那样才能学得更好。
了解古筝
古筝又名汉筝、秦筝、瑶筝、鸾筝,是中国汉民族传统乐器中的筝乐器,属于弹拨乐器。它是中国独特的、重要的民族乐器之一。它的音色优美,音域宽广、演奏技巧丰富,具有相当强的表现力,因此它深受广大人民群众的喜爱。
古筝的种类
古筝分低档古筝、中档古筝、高档古筝三种。
一、低档古筝是由普通木板做出框架,做工较粗躁,以花梨酸枝木贴皮,这种古筝声音较闷,弹不出古筝的韵味儿。
二、中档古筝琴是由花梨木酸枝木胡桃木做古筝的琴头琴尾,以及侧板,面板采用泡桐木,这种琴做工规范,弹出了古筝的韵味,但和中高档琴比音色要逊色很多。
中高档古筝是采用黑檀木老红木做古筝的琴头琴尾,以及侧板,面板采用泡桐木,这种材料做出的古筝音色清脆,韵味渐浓。
三、高档古筝做工严谨,选料精细,采用紫檀木血檀(雪檀)木做古筝的琴头琴尾,以及侧板,面板采用优质泡桐木。
近年雪檀已尽绝迹,紫檀也越来越少,这种材料做出的古筝音色纯正,颗粒性强,琴声韵味十足,余音较长,即余音绕梁乃三日不绝。
古筝分南北吗?
因为北方气候干燥,古筝使用中容易开裂,所以就流传出南筝、北筝的说法。
其实古筝是不分南北筝的,有些商家就是抓住了“古筝开裂”这一痛点,推出了南北筝这一概念。
古筝是不分南北的,也就是不分南北用琴。古筝核心面板都是泡桐木,泡桐木产自河南兰考,如果将河南产的面板拿回上海加工就成了南方古筝,拿回西安加工就成了北方古筝,这显然是说不通的。买古筝时最重要的是买适合自己的筝,且注意对其保养就行。
古筝琴弦
古筝是中国古老的民族乐器,距今已有两千五百多年的历史。
标准古筝有21根弦。从最细的弦到最粗的弦,依次编号为1~21。
最初的古筝,只有5根弦。经秦国著名将蒙恬改造后,古筝发展到12弦。在当时的历史条件下,应该说是对古筝成功的改革。12弦古筝延续使用了数百年,直到唐朝后期才出现了13弦古筝。
随着时代的发展,古筝的弦数也越来越多,音域也越来越宽。出现了16弦、18弦、19弦、21弦、23弦、25弦等,直到今天,发展成为通用的21弦。
筝身长1.63米的21弦古筝,被称为标准筝。筝弦,也由过去的丝,动物筋等生物性材料制作,改为现在的钢丝弦和尼龙缠弦。
随着筝弦的增加,筝的体积也在增大。发展到今天,已成为一种古朴典雅的民族乐器。
古筝基础知识
古筝的定义:弹拨弦鸣乐器。
一共有21根琴弦,包含17根弦和4根绿弦
1、琴弦:现多用尼龙缠弦,以不同型号的钢丝外面缠以尼龙丝制成的。
2、琴码(又称:雁柱):支撑琴弦,琴码的右侧为演奏区域,左侧为左手补韵的装饰音区域。
3、岳山:分为前岳山,后岳山,分别镶嵌在琴面板的首部和尾部。
4、面板:琴面略有弧度的木板。
5、调弦盒:内有弦轴,用于调音;琴盒内可以放指甲,琴扳手等物件。
认识SOL
认识简谱
简谱:简谱中用以表示音的高低及相互关系的基本符号为七个阿拉伯数字,即1、2、3、4、5、6、7,唱作do、re、mi、fa、sol、la、xi,称为唱名。
唱名:doremifasollaxi
音名:CDEFGAB这个就是用来记固定音高的符号。
在简谱中表达高低音一般会在上下两个方向添加小圆点。
中音是1234567那么低音表达就是在这些数字现面加一个小圆点,高音就是在数字上面加一点,上面加二个点为倍高音,加三个点为超高音。反之下面亦如此为倍低音、超低音等以此类推。
除了音的高低外,简谱还有一个重要的因素就是音的长短,简谱音的长短有多种表达方式,如基本的加小横线的方式。

五声调音
古筝采用的是五声音节,由这五个音构成的调式是五声调式。所以古筝琴弦上没有4(fa)和7(si)。
琴弦排列分组
筝架和姿势
弹筝的姿势有多种,一般采用坐式,要求坐姿端正,精神饱满、动作自然。古代采用过盘式、跪式。
由于流派的不同,筝的放置位置、筝架、琴凳也不同。
有的用琴桌式筝架,有的用类似人字形的筝架,还有的就放在腿上演奏。
采用琴桌式筝架比较稳因、牢靠,琴桌的面板有助于筝的共鸣。琴桌的大小应适当,恰好放稳筝的四个角;筝与琴桌之间有一定的空隙,以便于出音;琴桌的高低适合放腿为宜。此外,琴桌的造型应美观大方。
如采用类似人字形折叠筝架,应注意筝体能放置平稳,避免演奏中摇晃。
如采用小筝放在腿上演奏,小筝筝头底部应加筝托,以防止上身过前倾,腿部不要挡住出音孔,琴凳不要过高,筝尾支架的高度应与琴凳高度相当或略高。琴凳离筝体要近,尤其弹奏宽大的、弦数多的筝,一般身体前侧距筝体大约有6厘米至10厘米,应坐在靠近前岳山的位置上,坐的高低位置,应以方便演奏,便充分发挥技巧为原则。身体离琴过远,将使右手演奏困难,影响对触弦的控制;离琴过近,左手按弦困难,右手拨弦不方便;坐的位置过高时,上身容易前倾;坐的位置过低时,容易紧张。
弹筝的姿势,一般采用坐式,演奏者坐的姿势应该是:两腿自然分开,上身端正,两臂和双手松弛而自然抬起,精神饱满,态度自然。在演奏时既不要驼背也不要过分挺胸;既不要拘紧,也不要松垮。切忌摇头晃脑、脚打拍子等坏毛病。
正确的演奏姿势是:右脚蹬在固定筝架的踏板上,头部略俯视,双手按乐曲开头的指法自然伸出,做好弹奏准备。
如何选择古筝
古筝的统一规格为:1.63米,21弦。一台古筝的音质取决于面板和琴弦,面板以阳面中段为最佳,阳面是指整株桐木置于水中,露出水面的一面为阳面,去头斩尾为中段,一般以9-12年树龄的桐木为最佳,尤以河南兰考的桐木为最佳,沙土地,木质疏松,利于音质的传导。
初学者在购买古筝的时候一般不知道如何选择,市场上售卖的有练习筝、演奏古筝两种。
练习筝的制作较为简单,一般都是不包边的,而演奏筝的工艺更复杂,也更精美。同时,会因为木头的品质,和穿弦孔的工艺不同而导致音色和手感的不同。
演出筝对音色的要求更严格,音色要亮,所以价格一般比练习筝的价格贵。
古筝的结构说简单也简单,但是要让这简单的结构发出美妙的音乐就是技术活了。决定音色品质重要的部分是面板的等级,其次筝码、整体做工、制作工艺等,边板材质起到装饰古筝的作用,不建议作为选筝的重点。
古筝作为乐器其音色品质才是其价值的体现,而价值也是决定价格的原因,这也就是为什么古筝的价格会有如此大的差异。
我们选购古筝的时候首先要考虑古筝的音色问题,购买音色较好的古筝,如果是作为古筝学习者,练习筝也不要买太次的,那会影响自己的听力,和审美标准。
学习古筝
学戴义甲
大指:将义甲戴在指肚上,向指尖左上方斜出45度佩戴
食指、中指:将义甲戴在指肚上,顺指甲生长方向直戴
注意:佩戴时义甲不要挡住手指的关节;胶布的一半应覆盖在自己本身的指甲上。
选择指甲
古筝指甲首先要选择合适自身手指的长度,选择的指甲要和自己的手指第一节的长度相匹配,通常都是选择中号。指甲面选择宽点、上方尖点,不需要太厚的指甲面。古筝指甲材质很多,有塑料、树脂、玳瑁的,三种材质对比,玳瑁的比其它两种的好,对琴弦没有多大的磨损,但价格比较贵,塑料和树脂对琴弦的磨损就比较严重。
挑选玳瑁方法
1、强光照射法:把玳瑁放在太阳底下或者电筒光下投射,如果看见花纹、透明血丝状在甲片里,就是真品。伪劣产品呈现的血丝在甲面上是片状的,还有斑纹呆板或者团块状。
2、燃烧法:刮一点点的指甲点燃,或者用加热的针触碰指甲面,真品就会散发出烧焦头发的味道,伪劣产品是散发其它的味道,比如樟脑的味道、塑胶的味道、醋味等。
分辨琴弦
古筝的琴弦有21根弦,共有两种颜色,白色琴弦、绿色(或红色)琴弦。
绿色(或红色)琴弦都唱“5”(sol),共有四根绿色(或红色)琴弦,有粗有细,由细到粗,分别代表
高音5;中音5;低音5;倍低音5
第一根到第五根琴弦为倍低音,表示方法是在1、2、3、5、6下面加两个点;接下来五根弦是低音,在1、2、3、5、6,下面点一个点;在后面五根弦是中音区,1、2、3、5、6。接下来是高音区,五根弦1、2、3、5、6上方加一个点;最后一根为倍高音do,1上面加两个点。
练习古筝步骤
弹古筝,首先要保持正确的姿势。两只手的食指、中指、大指依次配戴好指甲,你可以买两卷医用胶带,一卷放手上保持手背的平直,另一卷用来配戴指甲。
眼睛平视乐谱,身体坐好,接下来开始古筝的练习。
佩戴指甲
弹奏古筝之前先要佩戴好指甲,指甲的大小应和手指第一关节差不多,戴在第一关节往上一点,胶布缠在第一关节中间,不要影响关节活动处,大指缠带方法与其他指不同,假指甲向内与指尖呈45度角,左右相对。
熟悉古筝音阶
音乐的七个基本音阶1(do)2(re)3(mi)4(fa)5(sol)6(la)7(si),古筝是五声音阶,没有4和7,只有1、2、3、5、6。
练习古筝指法
古筝演奏中常用到指法:勾、托、抹、劈、剔、挑、提、花指、摇指、琶音、泛音、按音、揉音、大撮、小撮、颤音、滑音等。
托-大拇指向外弹弦。?
劈-大拇指向里弹弦。
抹-食指向里弹弦。?
挑-食指向外弹弦。?
勾-中指向里弹弦。?
剔-中指向外弹弦。?
提-无名指向里弹弦。?
连托-大拇指向外连续弹弦。?
连抹-食指向外连续弹弦。?
大撮-大拇指向外,中指向里同时弹两弦。?
小撮-大拇指向外,食指向里同时弹两弦。?
双托-大拇指同时向外弹奏邻近的两弦。?
双抹-食指同时向外弹奏邻近的两弦。?
八度双托-大拇指向外弹奏邻近的两弦,同时中指在低八度另一音,三阴同时奏响。?
摇指-大拇指连续托劈。?
琶音-左手或右手用三个或四个手指按顺序弹奏不同的音。?
泛音-左手食指在发音弦1/2处轻贴弦,右手弹弦发音。?

向上刮奏-在筝弦上由低音向高音的划奏。?
向下刮奏-在筝弦上由高音向低音的划奏。
揉音或颤音-根据音乐的不同风格分类,是揉音类的,揉动较平和;是颤音类的,音波较密,也较有地方风格。?
重颤音-用力较重的颤音。?
按音-在弦上按出的音。?
上滑音-右手弹弦后,左手按弦,使音由低向高滑动。
下滑音-左手先按弦,右手弹奏后逐渐松弦。?
回滑音-右手弹弦之后,左手按弦使音由低向高又有高向低滑动数次。?
左手点音-左手马子左侧先轻点或轻轻快速下滑。

练习曲子
曲子是一句一句,一段一段地练习的,练得多了自然就记住了,然后可以脱离琴谱练习。
代表曲目
古筝十大代表名曲有《渔舟唱晚》、《高山流水》、《寒鸦戏水》、《汉宫秋月》、《蕉窗夜雨》、《林冲夜奔》、《侗族舞曲》、《东海渔歌》、《香山射鼓》、《战台风》。
《渔舟唱晚》是传统的古筝独奏名曲。一般以为此曲是娄树华在20世纪三十年代中期,根据古曲《归去来辞》的素材改编而成。取自唐朝诗人王勃的名篇《滕玉阁序》中的佳名:“渔舟唱晚,响穷彭蠡之滨”。
《高山流水》,为中国十大古曲之一。此曲最早见于我国现存最早的琴曲集《神奇秘谱》。乐曲取中国古代著名的音乐故事“伯牙摔琴谢知音”为题材,表现一种“巍巍乎若高山,洋洋乎若江海”的境界。
《寒鸦戏水》寒鸦又名鸥鸟,这是一首有名的潮州筝曲,是潮洲弦诗《软套》十大曲中最富诗意的一首。
老师指导
学习古筝需要有一个好老师指导,古筝作为一种并不那么容易学成的乐器,单靠自学是很困难的,因此需要找一个好老师。专业的好老师保证你能学到规范的指法、技巧和乐曲处理,不至于走弯路。
业余爱好者自学时,虽然有入门教材的辅导,但是自学难免会遇到许多不懂的地方,这时候就需要专业的老师进行解答了。其实刚开始的时候可以看视频资源、与许多古筝专业者或爱好者交流,不懂时还可以提出问题,这样总比自己一个人探索有用得多。
古筝是一门入门容易精通难的乐器,尤其是业余爱好者没有人监督,就更容易放弃,所以坚持才能成功。
选择古筝老师需要注意以下几点:
1、口碑;
大家选择古筝老师的时候还是要非常注重口碑的,如果身边有周围的朋友在学习古筝,我们不妨参考一下朋友的意见,老师的口碑如果好了,一般教学质量都挺不错的。
2、要去试听课;
古筝课都是可以提前试听的,我们可以参加基础的试听课程,如果你认为老师讲的可以很轻易的听得懂,而且讲的有非常详细,老师人也比较好,那么就可以考虑选择这个老师。
3、学历;
老师的学历也是比较重要的,我们在选择老师的时候我可以咨询一下老师是哪里毕业的,如果老师是正规的音乐学校毕业的,那么他学习的知识会更加系统,在教我们的时候条理会特别清楚。
4、专业性。
学习古筝还是非常需要老师的专业性的,老师水平比较高,比较专业,那么我们的学习质量也会更加的高。
自学选择教材
1、《古筝基础教程》
这本书分为古筝入门、古筝技法、古筝曲三个部分,是结合理论和实际的基础教材。
2、《古筝入门》
这本书介绍古筝由易到难,循序渐进,介绍的比较详细,里面附带很多筝曲。
3、《从零起步学古筝》
遵循从易及难的原则,从古筝最基本的指法讲起,每种指法配以相应的练习曲和乐曲。
我们学习的时候先学习基础知识,理论知识学会后可以在网上多看些古筝的教程,特别的视频教程,可以在哔哩哔哩上选择适合自己的配合教材学习。
不过刚开始学习还是不建议自学,毕竟我们对古筝琴音没用正确的认知,非常容易走入误区,只有在老师的带领下,感受到老师正确的琴音,才能慢慢培养认知,这个是教材和视频代替不了的。
古筝考级
古筝考级分为1-10级,其中1-4级为初级,5-7级为中级,8-10级为高级,高级需要加考乐理。
按有关规定,古筝考级一般是从一级到十级,由低到高逐级考评,但由于考级工作一般都是每年进行一次,而学古筝的每个人学习情况不同,因此可跳级报考,如果古筝学习的比较好,可以直接报考六级考试。
六级考试属于中等偏上的等级考试,考试相对简单,7级开始考试难度会增加很多。
所以刚开始考级的时候建议选择古筝六级考试,下面给大家介绍一些六级考试曲目。
古筝六级曲目有哪些
古筝考级六级曲目一般包括《高山流水》、《柳青娘》、《出水莲》、《崖山哀》、《庆丰年》、《闹元宵》、《山丹丹开花红艳艳》等,根据考级版本不同可能略有区别,例如有音协考级、中央音乐学院考级、民族管弦学会考级等,每个版本曲目和练习曲要求都不同。
考级的时候需要演奏两首同一级别的曲目,六级曲目中高山流水、庆丰年、出水莲为必选曲目。六级考试的要求是加强各种音色变化、控制力的训练,并进行一些特殊定弦乐曲的练习,演奏上必须按照其指法特点,应强调力度与音色的对比、演奏的投入及较好的音乐表现力。
调音器怎么用
古筝和吉他、钢琴等乐器一样都是需要调音的,最简单的方法就是使用调音器进行调音,具体的方法如下:
1、首先把调音器的电池装好,长按中间的开关打开调音器。
2、按开关键把屏幕左下角的字换成“自动”,按“M/T”键把屏幕右下角的字换成“古筝D”。
3、按上三角符号和下三角符号把左上角的数字换成“=440”。
4、把夹子夹到要调的那根弦的附近,这样更能使调音器取到音。
5、用古筝指甲拨要调的那根弦,看调音器屏幕上的数字,如果显示的数字比调的弦大,就说明太松了,如果数字比调的弦小,就说明太紧了,用调音扳手重新调整。
6、当屏幕上的数值是所调的弦的数值,还要看调音器最上端的三个指示灯,如果左边的红灯亮了,就说明有点偏紧了,如果右边的红灯亮了,就说明有点偏松了,如果绿灯亮,就说明这条弦已经调好。
日常保养方法
一般情况下,相对湿度在50%-70%之间的空间内使用古筝对筝的振动和发音都比较有利,湿度低于50%容易引发筝体表面及底板开裂,而湿度高于70%则易使面板吸潮,导致声音发闷、余音减短、音色发暗。
1、古筝在使用时应轻拿轻放,避免碰撞或剧烈震动。
2、若在北方地区使用古筝,在琴下放一盆水,增加空气湿度,防止开裂。冬季时古筝不能靠近散热的暖气片,以免出现曝烈或变形的情况。
3、古筝使用后可用干软布拭去琴弦上的汗渍,以防琴弦生锈,不用时要以筝罩盖好;
4、古筝应经常使用,这有利于琴弦张力的稳定,也鞥促进音色;
5、一旦发现琴音不准时应及时调音;
6、长时间不用古筝,只要防潮、防晒、防灰即可,不可将其放在地上或挂在潮湿的墙上。湿气较重时,将古筝放入盒内,并在盒内放入干燥剂。
