スズキの常識

As a beginner I use my tuner to tune my A string, then I tune the rest by humming up an down till I get the fifth, then double check my tuning with the tuner before I begin.

That is about all you really need a tuner for. I think you should be listening to the music you are playing (I second the Suzuki CDs, very helpful)and trying to get your tones to match the songs. Also, pick out some simple songs you like on the violin. Your ear will tell you if your note is out since it will sound wrong.
