Why Do Gut Strings Break?

Gut music strings can have a long life if they are properly cared for and stored. But, being made from a natural material, breakage can occur. Here are some common reasons why natural gut strings may break:

    • Natural Wear: Over time, gut strings can weaken due to the constant tension and vibration they experience during playing. This normal wear can lead to eventual breakage.

      Corrosion: Sweat and oils from your fingers can contribute to the breakage of strings, especially if they are not cleaned regularly. This corrosion can weaken the structural integrity of the strings and make them more prone to breaking. Our string varnish option can help mitigate this effect.

    • Environmental Factors: Changes in temperature and humidity (especially big swings) can affect the tension and condition of the strings, and can lead to the deterioration of gut strings and increase the likelihood of breakage. The proper care and storage of strings can increase their longevity.

    • Incorrect Installation: Improper installation of gut strings, such as incorrect (or cross-) winding, or excessive tension during tuning can lead to breakage. Gut strings are not intended to be used with fine tuners or string adjusters, and Gamut Music recommends removing those devices before installing the gut string on the instrument.

    • Sharp Edges or Burrs: If there are any sharp edges, protrusions, or burrs at all on an instrument's bridge, nut, or tuning pegs, they can cause excessive stress on that part of the string, leading to breakage. This is one of the most common culprits of string breakage with gut strings on a new (to you) instrument.

    • Overstretching: Rapid and excessive tuning changes can cause gut strings to be stretched beyond their physical limits, leading to breakage. It's essential to tune your strings gradually.

"Question — A pupil has a guitar and has used steel strings on it because he found he could not keep E gut strings on it. They all broke below the first fret. What is the best way to remedy this?

— F. K.

Answer — Many players have trouble with gut strings on a guitar and usually there is either something the matter with the strings or with the instrument or with the way the strings are picked. We wish to state emphatically that we do not advocate the use of steel strings on the guitar. We much prefer the gut strings. If the guitar which your pupil has is a standard make, the length of the fingerboard should be correct, therefore that doesn't cause the breaking of the strings. If the strings break at the nut or bridge, take a small rat-tail file and file the groove in which the string rests. Sometimes a sliver of wood will wear on a string and cause it to break. If the string breaks at the fret look all the frets over for a little sharp edge on someone of them. If the breaking is not caused by any of these things, look at the pupils fingernails and see that the fingernails are cut short so they will not touch the strings when playing, also only use the finest gut strings. If none of these points remedy the breaking of the strings you may rest assured that something is the matter with the instrument and should be gotten rid of and a new instrument of proper dimensions purchased."

The general reasons for string breakage applies to all types of strings. Regular instrument maintenance, proper playing technique (gradual tuning, avoiding over-tensioning), and a temperature- and humidity-controlled environment can help minimize the chance of string breakage.
