吉他的大小(尺寸、长度)是如何计算的?
作者:李健武 编辑  文章来源:厦门吉他培训中心  添加时间:2011-9-6  点击次数:30506

 

      吉他是西洋乐器,尺寸应该是指英寸。从以下表述就可以看出,古典吉他标准尺寸是39英寸(从琴头到音箱底部的长度,即吉他的总长度),民谣吉他是41英寸。吉他尺寸39、40、41主要指木吉他(声学吉他),电吉他少有此说法。也有根据琴弦长度、箱体大小来说明尺寸的,因为琴箱形状不固定,因此不具有说服力。

 

      1英寸=2.54厘米
      1厘米=0.39370078740157英寸

 

38 inches is probably a full size acoustic

Fashion 39 inch Linden wood Classical guitar inch
Model No. : RCG-1297
Top: Linden wood
Sides & Back : Linden wood
Neck: Maple
Fingerboard: Rose wood
Size: 39"

41" Acoustic guitar
Model No. : RFG-1831
Top : Solid spruce
Sides & Back : Solid Rosewood
Neck : Mohogany
Fingerboard : Rose wood
Size : 41"


      木吉他尺寸应该是从琴头最上边到箱体最下边的直线距离:39寸,40寸,41寸指的是英寸。1英寸=2.54厘米。41寸(英寸)=104.14厘米。依次类推。

      就古典吉他而言就有弦长650mm(标准的)、655、665、640、630、580、550mm等几种。西班牙吉他尺寸的数据参考下

Guitar size: (西班牙规格)
standard 650 x 52 mm
senorita 636 x 50 mm
cadette 580 mm (3/4 size small)
requinto 544 mm (1/2 size small)


      39寸为古典吉他标准尺寸,是一个标准。

      正规的古典吉他尺寸是39寸,而且为了音色的真实一般都是使用原色,不加任何有色漆,能清楚看到木纹。正规的民谣吉他尺寸是41寸,琴身后板为声学弧线,音量大,层次分明,这在不同价值的吉他中容易比较出来。那些颜色绚丽,款式多变的木吉他一般都是为了掩盖档次低的木料,吸引那些只重外表的购买者。

 
儿童古典吉他的选购:
①29寸儿童古典吉他适合3-6岁儿童
②30寸儿童古典吉他适合4-8岁儿童
③34寸儿童古典吉他适合7-12岁儿童
④36寸儿童古典吉他适合11-16岁儿童

 

      普通的吉他是41寸(104厘米)的,小一点的有40,39,38(96厘米)。大一点的常见的是43寸(109)厘米。38寸为练习琴,是中国特有的,为非标准吉他,用料、做工没有太多讲究,价格也是最低廉的。 在国内我们通常见到的大多数38寸木吉他都是“普及型吉他”,也就是通常所说的“练习琴”从木料材质到结构、作工、声学效果和演奏舒适度上都差很远,只是为了适应国内市场的消费水平而应运而生的一种廉价的入门型产品;一般38 39寸的吉他女生弹尺寸正好,40 41寸的吉他是大民谣 一般男生弹。

 


      40寸和41寸是民谣吉他。在同等材质、同等做工的前提下,琴箱大的琴音量大些。

 


      What Are the Different Sizes of Acoustic Guitars?


 
Acoustic guitars come in several different sizes.
 acoustic guitar image by Nicky Jacobs from Fotolia.com Acoustic guitars come in a wide variety of sizes, from the extremely small travel guitars, to large jumbo guitars. The most important factors when choosing an acoustic guitar size are sound quality and playability. In general, larger instruments are louder and have deeper, more rounded bass notes, but smaller guitars are easier to play and easier to travel with.

Travel Guitars
Travel guitars are the smallest acoustic guitars you can buy. They are often shaped strangely to accommodate easy travel. This type of guitar usually weighs three pounds or less. Travel guitars tend to have a thin sound, but they are ideal if you travel a lot, and want to take a practice guitar with you. Because of their size, travel guitars tend to be cheap.

Mini Guitars
Half- and 3/4-size acoustic guitars are also very small guitars. These guitars are small because they are designed specifically for children. Mini guitars are quieter than full-sized instruments, but they are also less expensive.

Classical Guitars
Classical (nylon stringed) guitars tend to be smaller than most of their full-sized, steel-stringed brethren. In general, these guitars are between mini-guitar size and concert guitar size, but there are many different classical guitar sizes. Classical guitars tend to sound warm and soft. As their name implies, classical guitars usually used to play classical music. The price of classical guitars varies depending on brand name and quality of the instrument.

Concert
The concert-style acoustic guitar is a common guitar model. These types of guitars would be considered medium sized. A good concert-style acoustic guitar will have a strong sound with enough volume to handle most acoustic guitar situations. A concert-style guitar is usually an "0" (in the number-sizing system originally devised by guitar maker Martin), depending on the thickness and body length of the guitar. 0 models are 4 1/4" deep, 13 1/2" wide at the widest point and 18 3/8" long for Martin models with 14 frets above the body. (12-fret models are slightly longer.)

Grand Concert
Grand concert-style acoustic guitars are slightly larger than the concert style. The actual body shape is slightly different as well. The major difference between concert models is the overall volume of the instrument. Grand concert guitars tend to be louder (and more expensive) than concert guitars. Grand concerts are considered 00 guitars by Martin. 00s are 4 1/8" deep, 18 7/8" long and 14 5/16" wide at their widest point. Non-Martin concert-size guitars are very similar to these sizes.

Auditorium
Auditorium-sized guitars are similar to grand concert-sized guitars, but they are even larger. The body on auditorium guitars is thinner than dreadnoughts and other larger guitar types, thus accentuating the higher-end tones instead of the bass notes. There are variations on this size guitar, including the grand auditorium and orchestra model. The main differing factor is the length of the bodies. Again, prices on these guitars can vary greatly. Auditorium guitars are numbered 000 in Martin's numbering system. 000s are usually 4 1/8" deep, 19 3/8" in body length and 15" wide.

Dreadnought
The dreadnought body style is the most popular modern guitar style. Dreadnoughts are large guitars that have strong bass tones and excellent sustain. Because of the size of these guitars, they tend to be quite loud. The size of these guitars makes them potentially difficult for smaller people to play. Dreadnoughts (D in Martin's system) measure 15 5/8" wide, 4 7/8" deep and 20" in body length. Guitars not made by Martin may not be these exact dimensions, but they will be very close.

Jumbo
Jumbo guitars are the biggest regular-production-model guitars. This type of guitar produces a loud, powerful sound. Sometimes, the term dreadnought is used synonymously with jumbo, that is not technically correct. Jumbo is the largest of the guitar types. This type of guitar is ideal for a player with a very strong strumming style. Jumbo guitars tend to be a little more expensive than smaller guitars simply because of their size, but the price is affected by many different factors. The defining feature of Gibson-style jumbos (the most popular of the jumbos) is their 17" width.
