The is the neck which is used so that

The body and neck both contribute to the sound of a guitar. Both the body and the neck consist of different woods of the same species which sound slightly different and have different weights and different densities. The types of body woods are alder, ash, basswood, Korina, mahogany, maple, poplar, rosewood, walnut, and exotics. The types of neck woods are mahogany/maple, mahogany/rosewood, maple, maple/Pau Ferro, and Maple/rosewood. When the strings are loosened, the pitch of the vibrating strings change. Tighter strings produce a higher sound than looser ones and longer strings produce a lower tune than shorter ones. Longer strings are freer to vibrate than shorter strings and tighter strings will vibrate more rapidly because it is under more tension which creates pressure waves that are closer together which results in a higher frequency. There are many parts of a guitar. The body of the guitar is described as the curvy part of a guitar, which rests against your body when you play. Another major component of a guitar is the neck which is used so that you can press down strings when playing. Frets are the bits of wire on the guitar. Finally the last most important part of the guitar is the soundhole which is basically the hole in the guitar that makes the sound. Wood is in a constant state of reacting to the environment. If the moisture level in the air is higher than the wood is, it will absorb moisture from the air until they are in balance. The reverse is also true where the wood will release moisture into a drier environment until it is in balance. When this shift is too sudden, cracks and warping can occur. So, to conclude temperature can affect wood. It seems like this experiment has been done before however with different instruments. With the violin, the warmer weather changed the amount of friction between the bow and the strings, changing the way the bow pulls on each string which changes the sound. Warm weather also expands instruments and change their ability to withstand tension, which again changes their interaction with a musician and the sound. It seems like temperature can affect an instrument.
