How would you create an enumeration of the musical notes in Java, with each notes having an octave and then a keyed variable? This is what I have so far...

    public enum Notes
    {
            c,
            cS,
            d,
            dS,
            e,
            f,
            fS,
            g,
            gS,
            a,
            aS,
            b;
            int octave;
            boolean isPlaying;
    }

So when I access the enums in my code I write something like this...

Notes.c.octave = 4;
Notes.c.isPlaying = true;

Now here is my question: How can I have an isPlaying boolean for each note in each octave?

Like so:

Notes.c.octave.isPlaying = true;

Or would I have to go like:

public enum Notes
{
        c1,
        cS1,
        d1,
        dS1,
        e1,
        f1,
        fS1,
        g1,
        gS1,
        a1,
        aS1,
        b1
        c2,
        cS2,
        d2,
        dS2,
        e2,
        f2,
        fS2,
        g2,
        gS2,
        a2,
        aS2,
        b2;

        etc...

        boolean isPlaying;
}

Thank you in advance for taking your time to answer this question!
