In what temperature does the violin case have to be when a is inside there?

Violins, like other musical instruments, are sensitive to temperature and humidity changes. While there is no single ideal temperature for a violin case, it is generally recommended to keep the instrument at a temperature between 65 and 75 degrees Fahrenheit (18-24 degrees Celsius). This range helps prevent damage to the instrument from temperature extremes, which can cause the wood to warp or crack.

It is also important to maintain a consistent temperature in the violin case, as sudden changes can also be damaging. For this reason, it is best to avoid leaving the violin in direct sunlight or near a heat source such as a radiator or fireplace.

In addition to temperature, humidity is also important in violin care. The ideal humidity level for a violin is between 40 and 60 percent. This can be achieved by using a humidifier in the violin case, or by keeping the instrument in a room with a humidifier.
