Classical acoustic guitars are among the finest instruments in the world. Classical guitars are not the same as the steel string acoustic guitars that are so familiar to those who listen to rock, country, or acoustic jazz music. Classical guitars actually do get used in those genres of music, and are not exclusive to classical music. But the steel-string acoustic guitars are used much more in rock, country, and jazz. The latter type of guitars also gets used greatly in Scots-Irish music.
Classical acoustic guitars are those guitars that have the relatively smaller bodies, the relatively wider necks, the more thinly cut wood for the bodies, and the nylon strings. These acoustic guitars are made in a particular way for pragmatic reasons.
They are designed to be played with classical guitar technique. This means they will be propped up one knee-hence, the lightness.
They are designed to deliver a fluid, silky sound. The lighter cut of wood facilitates this, too, and so do the nylon strings. The nylon strings also prevent your stripping your fingernails on your picking hand-very important, since you won't be using a plectrum, but your fingers, in order to set those strings vibrating.
The wider neck facilitates the fretting of chords using multiple fingers and the crisp playing of arpeggios. The techniques of hammer-ons and pull-offs are facilitated, too.
If you learn to play guitar, regardless of what styles most attract you, you should learn to play classical guitar. But, the question that you might have is: why? Or, why learn to play the guitar in the first place?
Learning the guitar improves your brain.
Playing music utilizes both hemispheres of the brain. And when you learn to play the classical guitar, you will need to learn how to read music and chord charts; memorize chords and scales; understand how to compose and improvise; and memorize songs and pieces of music, some of which will be quite complex and long.
You will need to use your muscles (in your hands and wrists), your eyes (to read music and chord charts), your ears (to recognize the sounds of notes, scales, and chords), and your whole brain (to memorize and read music, to have a sense of time-keeping, and to compose music). When it comes to playing guitar, your whole body and mind get involved. Your hand-eye coordination, your hand and finger strength, and your culture (music appreciation) all improve as you practice.
If you learn to play the guitar, you get a sense of accomplishment and pride unlike anything that you may have ever felt before. No matter how talented you are, learning to play the guitar at first is very hard. It will be easier for you if you already play another instrument. Once you push past that difficulty, and start making progress, your sense of self-esteem and pride will soar.
It's great interacting with other people through music. Consider the selection of acoustic guitars in which to find your chosen instrument, and seriously consider classical guitars among your possible choices.
