There are a couple of places you can buy or rent an instrument and accessories: Amro in Memphis, Little Rock Violin Shop, and Shar Music in Michigan (They can ship things and have excellent customer service.).

Be sure to read the paragraph on the Little Rock Violin Shop page: “What's wrong with buying a beginner/a bargain instrument from the internet?” Basically, buying a cheap instrument on the internet comes with the hidden cost of set up and repair bills of $75-$200, often exceeding the instrument’s original purchase price.
If you’re an adult or a high school student, you'll need a "full size," also called "4/4" size violin. For children, you will need to measure their arm length and refer to the chart here. Consult the violin shops listed above more assistance on sizing.
When you buy or rent a violin or viola, a basic "outfit" means that it comes with a bow and a case.
You'll also need to have:
1. rosin
2. extra set of strings
3. shoulder rest
4. folding music stand for practicing at home
5. tuner*
6. metronome*
7. original sheet music or music book
*You can download a free app on your phone for tuning and a metronome, or you can buy a combo tuner/metronome.
Optional for beginners: “finger guide”
