I play jazz standards on my violin. I'm thinking how to make my violin sound like a jazz singer or improvise like Stephane Grappelli. Tall order, I know?

I'm only learning for about 3 months, and working hard on intonation with a tuner. 

On a side note, does anyone know how long it takes to work on intonation with the tuner, before every note falls into place, assuming an hour of practice daily?

Thanks Fiddlerman and damfino for your advices.

I will ditch the tuner soon. I also refuse to use position markers even though 2 teachers have advised me to do so. I mostly rely on matching intervals of jazz standards e.g. Over the Rainbow's Octave, Isn't She Lovely's Minor 2nd, Georgia's Minor 3rd etc. 

So to answer this topic's question, when i play jazz standards, I also think about intervals and attempt to remember the sounds.  

I recently read about the use of drone tone, but personally don't find it enjoyable as compared to using intervals. I would like to hear of how others learn to improve intonation.

My other attempt to train my ear is to figure out the tunes by ear and rely lesser on reading fakebook.

I have been playing chord-melody pieces on guitar for years. But only with violin that my ear is put to the test.

fulfillingsoul, my advice, as a fellow beginner, would be to put away the tuner, and really let your ears and fingers do the work. Get rid of the crutch as early on as you can. It's hard to train your ear when you're training your eyes to watch a tuner (or finger markers). I'm sure you know what the notes should sound like, and will surprise yourself
