Sounds like a Black House/Window Spider, pretty rare but they are poisonous so stay away. Kill it with a big stick from a distance!
Brown recluse
A fiddle spider(also called the violin spider or the brown recluse) is a medium-sized venomous spider of North America. It is easily recognized by the violin shape on its abdomen.
You would first have to check the size of the spider. If it is a huge spider, it is obiously a tarantula. (Depending on location, very unlikely that it is a tarantula) If it is small, check for violin-shaped markings on the abdomen (the 'violin' markings of the brown recluse are on the cephalothorax where the legs are attached). If there are, the spider is a brown recluse. Depending on location, size, body shape, coloration, web or not, and where in your house, it could be any number of harmless spiders. A more detailed description would yield more information. ---------------------------- If it has a violin on it's back, kill it immediately! It's a Brown Recluse (A.K.A. The Violin Spider). The Brown Recluse has an acid-like venom that melts skin tissue, muscle & fat. If it's fuzzy, kind of large, & somewhat bright, also kill it immediately. It's a Wolf Spider. Their venom isn't deadly, or nearly as toxic as the Violin Spider, but their bites are very painful, they swell, they itch, & in some cases, can make you nauseous.
Only a few species are seriously poisonous to humans. There are these few Spiders: black widow, African brown spider, bird spider, and if you ever see a spider with a violin shape on its back stay clear this spider can kill and is known for it. *Edit: The violin spider (or Brown Recluse, Loxosceles Reclusa, or Fiddleback spider) mentioned above is NOT deadly. It is difficult for doctors to diagnose spider bites, and the bite of this particular spider looks very similar to other serious conditions, so a lot of pictures/stories you see/hear about this spider being deadly are false. Though not deadly, this spider does cause very serious wounds and should be avoided. It is not aggressive.
it is sort of a brown/tan color and in the middle of the spider you will see some sort of a violin and if you do see one be extremely cautious! Don' get bit!!
