Does relative pitch come naturally with time if one plays the violin long enough?
Or does one need to actually undergo training to attain it?→ and if so is there a recomended method?
You need to think and tell us exactly what you mean. If you can sing a song accurately in more than one key you have a form of relative pitch
It comes naturally the more you play scales and arpeggios and work your way through repertoire. Especially when you start working on double stops.
Like practising a piece. You can learn it by running through it a million times, or you can learn it by breaking it into a million tiny bits. And then doing technical exercises to master those bits.
I'm still not entirely sure what you mean. Being able to name played or sung intervals is useful enough but being able to make a mind's-ear connection between the separation of two notes on the stave and the interval you expect to hear when you play them is of greater value. From my own case I don't think it comes automatically!
In addition to the above advice; playing second violin or viola in a good quartet that rehearses intonation is part of the process.

If you can you sing a song in tune you have relative pitch. Chances are if your mother (or father) sang to you in tune you acquired a sense of relative pitch when you were young. (I read long ago that people who were raised by "mothers" who sang out of tune have more trouble with this than others.) If you can copy Julie Andrews' "Do-Re-Me" regardless of the speed of the playback (changing the playback speed would change the relative pitch) - you've got it!
@Andrew - I love the post but have a small correction to offer - surely you meant to say changing the playback speed would NOT change the relative pitch! Sol will always have a 50% higher frequency than Doh.
Ivy I suspect you have relative pitch already and the real problem is making those pitches on the violin and being afraid that they aren't close enough. I think this is a common and valid concern. This has more to do with muscle/finger memory in relation to notes played. I believe it begins with playing material that you are very familiar with. In this way you will know if it sounds right in relation to your playing. Playing to or making backing tracks can help. I have made a few backing tracks that work well for this.
Steve, my point on changing the playback speed was that you will have the same relative pitches of the notes (each longer or shorter, of course) - just different absolute pitches (i.e., transposed).
