I love to play guitar. The six strings and the frets help to make the most beautiful sound.
I don't know much about guitars. My son has one.
Is his an acoustic with a hollow wooden or plastic and wood box, or an electrically amplified guitar?
His is acoustic. 
Someday he might even like to try a jazz guitar that was invented once electric amplification increased the volume of the traditional acoustic guitar.
Sounds like it would have a nice sound.
It does. It is mostly used to play styles of jazz music.
I really think the acoustic has the best sound though. 
Everyone has their favorite. The acoustic guitar's tone  is produced by the strings' vibration and amplified by the hollow body of the guitar which functions as a resonating chamber.
All music is certainly beautiful.
