Out of the hundreds of acoustic guitar models, the inexperienced will likely have a hard time trying to figure out which is better, so below is a very rough guide to give them a starting point.
Wood and sound
Quality acoustic guitars combine a beautiful design with a sturdy construction; therefore, you will notice that the best acoustic guitars have a cedar, rosewood, mahogany or spruce body, fingerboard, neck and bridge. Since the choice of wood influences the quality of the sound, most of the classic acoustic guitars are made from cedar due to its deep tone, while rosewood guitars have a rich ring to them.
If you already know what kind of music you would like to play and what type of tone is more appropriate for your style, your task of picking the best acoustic guitar will be much easier. That is because specific body styles render specific sounds and tones; for instance, a bigger soundboard will determine a lower volume and tone.
How strings influence music
Moreover, the strings have a direct bearing on the type of music you will play. Acoustic guitars use two types of strings: nylon strings and steel strings. The former produce soft tones and are more suitable for Latin and classical music, whereas the strong bold tones of steel strings are better for pop music, jazz and modern rock.
Other technical considerations
Depending on the age of the player, guitars can be full sized or smaller, ¾ suitable for children, but quality is a must, especially when you just start learning to play guitar. Finally, the neck should be straight and rigid, and match the size of your hand if you are to be able to hold the guitar comfortably at all times for the sound to come out right. If you still have questions, take some time to read the best acoustic guitar reviews on the web before making your decision.
