Violin Key to Key Signatures!

If you teach any string orchestral instrument I hope you share this cool fact with your students! My students think it's pretty cool :) 

There are patterns in the strings and finger patterns on the Violin that equal the order of Major sharp scales, order of sharps and even the order of Major Flat Scales.

Sharp Keys

The Major sharp keys match the violin strings from low to high: 
How many C strings do we have?  Zero! Tha'ts right. There are 0 #'s in C Major. 

The first string is G so G Major has 1#.

The second string is D so, you guessed it 2 #'s. The same goes for the 3rd string A and the 4th string E.

C strings=0#'s, 1st string G=1#, 2nd string D=2#'s, 3rd string A=3#'s, 4th string E=4#'s
Order of sharps? Move down the strings high to low as you climb up the fingers starting with high 1 on the E string, high 2nd on A, high 3rd on D, and high 4th on G

Order of Sharps

Start on the E string and put your first finger down on F#. You're first finger on the E string is the first # added in any sharp key signature.

Now move down one string to A and use your high second finger, C#. That is our second # in any sharp key signature. 
Next comes the D string high 3rd finger for G# and the G string high 4th finger D#.

So starting on your highest string play your high 1 then 2 then 3 then 4, moving to the next lowest string each time. 

E1=F#, A2=C#, D3=G#, G4=D#

Flat Keys

We can find the Flat Key by hopping a low first finger across the strings from high to low.

(E string) F -1b,

(A string) Bb-2b's,

(D string) Eb=3b's,

(G string) Ab=4 flats
