3. 徕卡typ107样片
leica x vario代号为"typ107"画质挺好的。因为徕卡x vario是不可更换镜头的,采用APS-C画幅的CMOS传感器,配置了固定的等效28-70mm徕卡Vario Elmar变焦镜头,属于德国本土生产的机型,非松下代工。
leica x vario:

4. 徕卡typ113参数
尝试用光影魔术手软件检查照片exif属性
据我了解,这相机很可能查不了快门数而且多数相机快门数可以修改建议多检查机身外观和功能
5. 徕卡typ109参数
XV是德国原装的,D-lux109产地是日本的,在纠结如何选哪一款,我这里给你一下建议希望能帮到你。
第一从机身功能上来说:D-lux是偏向于电子更浓烈的卡片小机器,机身比较小巧,功能更全,比如wifi传输,电子取景器这两点,都是xv不具备的。第二机身画幅:一般来说,机身传感器画幅的大小决定成像细节的质量,很明显XV的传感器的成像质量从细节上来说很定要比D-lux要好,这是毋庸置疑的,但是他们同属于入门相机,徕卡M旁轴系列才是徕卡的精髓所在。要是注重画质肯定是选徕卡XV。个人建议你要是专业玩的话还是选定焦的,XV和D-lux同属于变焦相机,因为镜头的结构因素,所有的定焦头的成像素质是都要比变焦头要好,所以徕卡M旁轴系列几乎都是定焦镜头的原因所在。第三从自身考虑:你要是自己旅游拍照的话肯定还是变焦适合你,因为可以拉远拉进着实方便,玩专业你可以考虑下入手徕卡X 这款是定焦的,价格比XV便宜,比D-LUX高。但是,这里你要只是想买个徕卡的牌子用来旅游家庭拍照玩玩的话还是建议你选徕卡D-lux。这款性价比在徕卡里是挺高,功能也完善,相机的拍照模式也比XV丰富,要是真是不差钱就入手M机身,但是M都是全手动的,初级玩家可能会用不好,比较专业。回答:tao.baodianpu 光影徕卡6. 徕卡typ112参数
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:do re mi fa sol la xi
音名:C D E F G A B 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。
花指-大拇指迅速连托数弦。
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。
下图是古筝指法符号对照表,在看古筝简谱的时候可以用到。

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。
