I was listening to some fiddle music the other night and I started wondering : How many strings can a good fiddler bow at the same time ? I know that the neck has a curve to it - so can you bow all four strings at the same time ? In the piece I was listening to it sounded like three strings were being played at once so I couldn't tell if it was multi-tracked. Does it take a lot of strength in the wrist to bow all four strings ?

And the bow - I assume that only horse hair is used to make bows correct ? In other words - in the song "Wind and Rain" when they say "He made a bow of her fine yellow hair" - thats not possible correct ?

One more - if the fiddle is extended in front of you how can you see properly to tell where you should place your fingers in order to be spot on tune ? Guess a lot ? At least on the mandolin you can see the fretboard when you play.

Thanks
