There are two main types of guitar - Acoustic and Electric. You can learn on either type, it really depends on what music you like.
The sound from the strings goes through the bridge into the acoustic chamber.
|Nylon strings: Generally a soft tone, used for Classical, Folk and Flamenco.|
|Steel strings: A bright strong sound, used in all styles and is both picked and strummed.|
The sound is transmitted through electric pick ups and played through an amplifier. The tone can be very extensively modified by effects and the amplifier.
|Solid body: rich in sustain|
|Hollow body: note the ƒ hole|
|Steel string archtop: often with pick ups, it’s halfway between an acoustic and an electric|
