If something had 8 intervals is it automatically a Perfect 8?

If something has 7 intervals is it automatically a Major 7th?

If something has 6 intervals is it automatically a Major 6th?

Thanks.

If something had 8 intervals...

If something has 7 intervals...

If something has 6 intervals...

What do you mean by if something has X intervals?

#3

What do you mean by if something has X intervals?

A-B has 2 intervals.

C-C(octave) has 8 Intervals.

A-D has 4 intervals. And so on and so on.

#4

A-B has 2 intervals.

C-C(octave) has 8 Intervals.

A-D has 4 intervals. And so on and so on.

I wouldn't say that's correct. A-B is a 2nd, it doesn't have two intervals, it is a 2nd interval.

To answer the threadstarter's question: No. It's a perfect octave if the second note is 8 notes away and part of the base-note's major scale.

Ah, I get you. You mean diatonic steps? That's what it looks like you're describing, in which case, apart from 8 diatonic steps always being a perfect octave, no - it won't always be a major 7th or major 6th, or any other interval.

C - E is what you desribed as '3 intervals' and is a major third, C - Eb is also three diatonic steps, but is a minor third.

Of course, if you're specifically referring to only the major scale - then you would be correct in saying 6 diatonic steps from the tonic will always a be a major 6th, and so forth.

Still not sure if I understand you properly though.

See I have a book here that says C is a perfect octave, with C because it is 12 half steps away.

A-B has two intervals, but B is the second Interval. Im counting the root note as an interval because thats how my book says to do it.

Edit-

Alright thanks Jones for the help

12 half steps, or 8 notes, including the root. You should always count the root note in the interval, but know that a 2nd is 2 note names, a third 3 note names etc. Don't count intervals by chromatic half-steps.

Yea sorry bout that, my book used half steps and intervals. 12 halfsteps= 8 intervals. 11 halfsteps= Major 7, or 7 intervals.

thanks for help.

You are on thin ice here, friend. The correct and safe way to determine intervalYea sorry bout that, my book used half steps and intervals. 12 halfsteps= 8 intervals. 11 halfsteps= Major 7, or 7 intervals.

*(as opposed to interval*

**size***) is to look at the notes as depicted on a staff.*

**quality**Starting with "1" at the lower note, count every line and space up to and including the upper note. The ending count is the

*of the interval, period, end of story. There's literally nothing else to know about determining the*

**size***of the interval.*

**size**Determining that interval's

*is another process altogether.*

Simply put, no. It depends on the interval. A perfect 8th (or octave) has an interval of 8 notes in a major or minor scale. And in a major scale, 7 notes would make a major 7th. But you need more information. In a minor or modal scale, your statements could be incorrect. It all depends on what scale you're in and the differences between the gaps in tones and semitones.
