The video above shows the transistor oscillator that I built. I've included the schematic for it below the video. You can see in the video that I've added a potentiometer to one of the 1K resistors in order to tweak the pitch of the sound. This is a very simple oscillator and a good project to start with if you are interested in understanding electric currents and their relation to the production of sound.
Thanks. This help clear up some things.
