What can cause a guitar string to break?

Guitar strings can break for a number of reasons, including:

Age

Strings can become oxidized or worn out over time, making them more likely to break.

Rough surfaces

Burrs or sharp edges on the saddle, nut, tuning machine, or frets can snag or wear down strings.

Cleaning

If you don't clean your strings after playing, debris and gunk can build up and cause the metal to oxidize, making it more likely to break.

Metal fatigue

Winding strings incorrectly around the tuning posts can cause kinks in the wire, which weakens the string and makes it more likely to break.

Corrosion

If you don't store your guitar in a climate-controlled environment, corrosion can destroy the strings.

Alternate tunings

Using the wrong string gauge for the tuning you're playing can also cause strings to break.

Pick

The thickness and sharpness of your pick can also affect how long your

strings last.
