Please help me identify a bird with little to go on.

I am going by the call the bird makes and I cannot for the life of me spot which one is the one making that beautiful song. It almost sounds like a guitar riff from a Metallica song, the notes, I mean.

The first note is higher
The second note is slightly lower than that
Then it ends with several (about 6 or 7)short notes in a row that are lower than the second note.

The closest bird I spotted from that direction just now was a goldfinch. I like in central North Carolina (the sandhills, not the foothills) if that helps any. I have looked up goldfinch calls online and the American Goldfinch isn't the one. I will continue to look as I realize this is very little information to go on, but when I do find it, it'll officially be my favorite bird call of all time.

1. The first two notes sound just like:

the first two notes in this audio of a Black Capped Chickadee:

2. What's the tonal quality of the song?

Is it clear and whistled, or is it a little "burry" or "squeaky?" Or any other quality?

Are the last few notes evenly spaced, or do they make a "bouncing ball?"

And does it sound like the bird is just singing one note, like the Chickadee song, or does it sound like the bird is whistling more than one note at any time? :shrug:

Finally, it isn't a White-throated Sparrow, is it? I know it's not exactly like your description, but they're sorta similar...

3. The first two notes are identical to the

black capped chickadee at this link:

but the last notes are more sung that chirped. They are like staccato repeats, but sung in a crystal clear "voice."

It almost sounds like a cross between the two.
