Well, the title says it. I have recently recieved a hand out from my strings teacher showing how to play scales starting on the second finger. Under this, I have to start in second position to start the C Major scale. It says that you have to play like this...
G D A E
2 3 4^|1 2 3 4^|1 2 - 1^2 3 4| 1^2-1 2^-1 2 3 4^ -4^-4 3 2 1^-3 2 1^-3 2 1|
A D G
4^3 2 1^| 4 3 2 1^| 4 3 2

I also understand that I have to put my fingers according to the half steps, but I`ve never heard a C Major 3 Octave Scale. Does anyone have a file that I can download and listen to to I can heard what it sounds like?

You don`t need a recording. You have your voice and your inner voice for knowing what the scale sounds like.

Play the c on the G string (3rd finger, using 1st position). Find that "C" by doing do ray mi of the g major until you get to the "C".

Once oyu have that "c" sing it -- if oyu run out of range, sing in your head.

Next, play the two octaves that you can in 1st position (you will have to shift the 4th finger on the e string to achieve the high c)

Finally, switch to 2nd position, and play the scales. You go by ear--by your sense of your inner voice. Don`t thing about sharps/flats, think about pitch, and you will pull your fingers to the right places.

Well said, violasurvey. It may help to play the high C twice at the end of each octave (once as the last note of the lower octave and once as the first note of the higher octave)...that may help you to hear the proper pitches in your head and know where you are in the scale.

Good luck and take your time with each note until you hear it exactly in tune.
