What is string tension? Let’s go for physics for a moment. The force on the end portion where a metal or any string is attached and the string is putting a pressure at the opposite side of the end part. Then genera6, the string will get stretched. While this stretching happens, a force is directly being applied to the end portion. This is called tension. Now the question is how selection of a ukulele is depending on the string tension. How much force is being applied to the end part and how strong the wood is at the end part, always depends. Afterall, the wood has to take care of the pressure and gives the acoustic. You can easily learn more about soprano vs concert ukulele by checking out the site.
If you think for a second, you can understand the point, mentioned above, the tone and the scale length are somehow depending on string tension. Let’s know how it is happening. When your strings light weighted and is tightened with the end you can feel the strength when you touch with your finger. And according to verifying the strength and the tuning sound we decide how much the knob has to be tightened. Right? While doing this, what do you do? While verifying the sound, don’t you want to listen to the sound carefully? While it is echoing or stable? Right? Now, if the wood is light and the string has no tension, no proper vibration will be generated and no proper sound reflection will be felt by the listener.
In the case of soprano and concert ukulele, for both of these, a metal nylon string is being used. Exceptions are always there. But overall it happens. As you know, because of the light weight, sapele wood or rosewood are being used. Those light woods can’t bear too much pressure. That’s why the string tension is being loosened. And for concerts, it is vice-versa. The string attachment and tension can be felt very properly.
