How do I learn to play a vibrato on my violin?

I have played violin on and off for about 10 years, but still pretty much a beginner. I do not take private lessons today, but I am very interested in learning tips to develop a vibrato. Any suggestions – tips, books, websites that could help? Thanks in advance.

how to learn to play drums without drums?

I do not have the money to buy a drum set, but I really want to learn to play drums? The only thing that I would afford to buy is a pair of drum sticks. I’m 20 and I think it would take me a few years to save up the money to buy a set (even the basic ones) since I can’t get a job now and I’m still in school. My question is, could I learn by using the drum sticks that I have and hitting on different surfaces around my house like the table or the chair?

Thanks in advance!
