A 3/4 size classical guitar is a smaller version of a standard classical guitar with a reduced scale length and body size. It is commonly used by children and beginners because of its easier playability due to the smaller neck and frets. The sound produced by a 3/4 size classical guitar is generally softer and quieter than a full-size guitar but still has a rich, warm tone. The smaller size and lighter weight also make it more portable and easier to carry around.
