Don't know if this got through. I'll try again.

Major Scale: sing it. 1,2,3,4,5,6,7,8

Harmonic Minor Scale: sing it 1,2,b3,4,5,b6,7,8

Natural Minor Scale: sing it 1,2,b3,4,5,b6,b7,8

It's important that you hear how the minor scales are altered by the b's (flats) from the major scale. sing em, sing 'em, sing 'em.

Now when you can hear those scales, the next step is to learn the key signatures for sharp and flat keys. (This is the hard part)

Once you know that then you look at the dots...find the key and write the numbers above or below the notes. Then sing 'em.

So if you are for example in the key of D, you gotta' know that it contains two sharps, F# and C#. So: D is 1, E is 2, F# is 3, G is 4, A is 5, B is 6, C# is 7 and the high D is 8.
                                                                                             3   (etc.)
                                                                                       2
When singing these numbers I like to space them: 1

Reading the rhythm is a whole different topic.

You may not be able to apply the above information without help. But that's the road map. When you see the pitch relationship in the notes as defined as a pitch number, then you're hot on the trail.
