Quick musical notation question?

Quick musical notation question?

I'm a violinist that's out of practice, so when I recieved a piece of hand written sheet music, much to my humiliation, I wasn't 100% sure of a certain notation, a diagonal slash, sometimes two, that runs through the stem of the note.

I'm pretty sure it means to accentuate or something, but as a violin, am I suppose to trill? I know to most this is going to sound like a ridiculously easy question, but I've just forgotten, and I've been playing a trill on those notes in the meantime. Help?

Best Answer - Chosen by Asker: This is not a trill. It is an indication for you to play that note as either eighth notes or sixteenth notes. One slash means eighths.... two means sixteenths. For instance, if you have an "A" with two slashes, you play an "A" 4 times in a sixteenth note pattern (1-e-+-a if you use that counting system).

Hope this helps. Have fun!
