The history of luthiers in Korea had begun by Uhm family since SangOk Uhm built his first guitar in 1932.

TaeHeung Uhm says that the sound of guitar is just like the circle consisting of two different layers.

One is the "core" which gives the power of the sound and the other is the surface layer (He calls this "skin" of the sound) which softly surrounds the core so that this skin adds the beauty of the sound to the power.

For the perfectness of the sound, the core should be hard, heavy and large enough so that the sound can be delivered with strong power of impression. At the same time, the skin is supposed to be soft and delicate so that it could express the emotion and the beauty of the music. The perfect balance between these two essential elements is necessary for creating a great sound of the instrument.

Many famouse guitarist explained Uhm's sound as
"The trebles of Uhm's guitar have quick response. The color of tone is very clear, bright and sharp. At the same time, three bases have well separated, remarkable sounds. The shape of neck is very comfortable, thus it is easy to play."
