I tried experiment (2), singing directly onto the back of the violin. Th e amplitude was about the same as it was when I sang directly at the string on the front of the violin. The resonator (the body of the violin) does not respond to the pitch by itself - I don't get a sympathetic ringing at the pitch if I hold all the strings (both sides of the bridge) so that they cannot vibrate. So I think the frequency of the pitch I'm singing must be transmitted by air to the string, and the loscloser my mouth (the sound source) and the louder the pitch, the better. Probably then the resonator and the string intereact, transmitting the vibrations back and forth (since they're connected) so that the resonator amplifies the sound of the violin.
