second or a seventh

[wiley]

Working on theory - I'm sorta/kinda confused about a specific interval.

Using the Scale - C (C Major) a 'second' is "D", of course. That is, going 'up' in tone - Using the 'scientific' method, let's make this a C3 - meaning the D3 is a 'second'

Now, going down in tone - from C3 to B2 - seventh, or second? (*One half step, one fret down)

I'm not asking about the semi-tone or if the tone in question is "Major" or "Minor" - I get that part.

Just if I'm working a specific scale, and I go 'down' in tone.....is the B still not a part of that scale and what is it called?

Good question,
I'm not sure about this but we all know C to B or (C2 to B2) is a major seventh.
If you move the C note an octave (B2 C3) maybe we should call this an inversion.
And if this is true, B2 to C3 is a minor second (major seventh inversion).
I hope this makes sense

I get that this would be an "inversion" if we were talking chords (or, in this case a 'power' chord) but how about in the degrees of a scale? Or perhaps better stated, the intervals of a scale?

Intervals can be described as up or down but if you're thinking down you would phrase it as a minor second below.

Thanks Neil.
