What are harp strings made out of?

* Gut: Traditional harp strings are made of sheep or cow gut. Gut strings have a warm, mellow sound that is often preferred for classical and folk music. However, gut strings are relatively expensive and require regular maintenance, as they are susceptible to stretching and breaking.

* Nylon: Nylon harp strings are a synthetic alternative to gut strings. They are more durable and longer-lasting than gut strings, and they are not affected by changes in humidity. Nylon strings have a brighter, more modern sound than gut strings, and they are often used in folk, rock, and popular music.

* Steel: Steel harp strings are the most durable type of harp strings. They are made of high-tensile steel wire, which makes them resistant to stretching and breaking. Steel strings have a bright, clear sound that is often preferred for Celtic and bluegrass music.
