const array declaration in C++ header file
===

I have a class called AppSettings where I have an Array with a range of note frequencies. I'm getting several errors with the code below and I'm not sure what the problem is.

The error messages are:

 - `static data member of type 'const float [36] must be initialized out of line`
 - `A brace enclosed initializer is not allowed here before '{' token`
 - `Invalid in-class initialization of static data member of non-integral type`

And the code:

    class AppSettings{
        
    public:
        static const float noteFrequency[36] = {
        //  C       C#      D       D#      E       F       F#      G       G#      A       A#      B
            130.81, 138.59, 146.83, 155.56, 164.81, 174.61, 185.00, 196.00, 207.65, 220.00, 223.08, 246.94,
            261.63, 277.18, 293.66, 311.13, 329.63, 349.23, 369.99, 392.00, 415.30, 440.00, 466.16, 493.88,
            523.25, 554.37, 587.33, 622.25, 659.25, 698.46, 739.99, 783.99, 830.61, 880.00, 932.33, 987.77
        };
        
    };

As the name suggests this is just a header file with some settings and values I need throughout the app.
