How to Change Notes on a String Instrument

The way we change notes on a string instrument, we have what we call a fingerboard. When we put our fingers down on the string it changes the pitch up or down. So if I play my A string and then I put my finger down, I change the note higher by one note. And you can do a lot as much as you can do with your fingers. You can make all different sounds depending how close to the bridge and how far away from the bridge you are.
