If your ukulele is a common nylon string in the country, it is generally necessary to maintain the tuning for about half a month. In the past two months, the tension of the nylon strings is not enough, so you must remember to tune before you play.
However, there is also a string that only takes about five days to adjust the temperament. This is the imported carbon string. This carbon string is much better than the ordinary nylon string. It is easier to fix the sound, and it is not easy to run. It can avoid the broken string. In addition, this carbon string is softer than the nylon strings, and the damage to the fingers is smaller, and there is no pain in the fingers.
