Okay so I understand the intervals. Only i'm not too sure about 1 thing.

This is a perfect 5th interval:

D|----7-

A|-5----

E|-------

How do you call this:

D|------

A|-5----

E|----5-

If you take the D on the A string as the root, I'd say an inverted 5th(or a 5th an octave lower), but you could also say it's a perfect fourth.

So if someone would tell me; "Go down a minor 2nd", does he mean example A or B?

*A* (You could see this as a maj7th (an octave lower), if u take the G note as the root.)

D|-5-4---

A|--------

E|--------

(Up a min2nd is 1 semitone up, so can you also see it as a min 2nd if u go 1 semitone down?)

*B* (is the min2nd interval if u take the G note as the root, but an octave lower)

D|-5----

A|-------

E|----4--

It's called an inverted fourth.

And if someone says, down a minor second or down a semitone (far more appropriate) he means instead of playing a C you play a B.

Ah okey tyvm

An interval is the distance between two notes starting from the first played so

D|------

A|5-----

E|--5---

is a perfect 4th.

Always take the first note as the root. Down a minor 2nd is B to A going down

D|5-4---- is a minor 2nd

Hope this was helpful

That's right. It's an A and a D. The D, being in the higher register is a perfect fourth above the A. This means the A is also a perfect fourth below D. There is nothing "inverted" about the fourth. It is a perfect fourth interval. ( The inversion of a perfect fourth is a perfect fifth. That interval is not a perfect fifth, not seven semitones therefore not an inverted perfect fourth. It is simply a perfect fourth.)

However a perfect fifth and perfect fourth are inversions of each other. Meaning A

**up**to D is a perfect fourth. D

**up**to A is a perfect fifth.

Similarly, going down. D

**down**to A is a perfect fourth. A

**down**to D is a perfect fifth.

You could call it an inverted prefect fifth. Or you could call it a perfect fourth. I think the difference is your reference note. However even in the case of the reference note being the A it could be called a perfect fourth

*down*. The

*down*being an important appendix.

If you think of intervals as a set number of semitones where a perfect fifth = 7 semitones, when someone attaches the appendix

*down*they mean descend from the starting note to the note 7 semitones below.

Hence,

a perfect fifth above A is E and a perfect fifth below A is D.

a perfect fourth above A is D and a perfect fourth below A is E.

This is why they are inversions of each other.

Quickie answer - an interval is the

*distance*between notes, not the direction.
#7

Here is an easy way to figure out the inversions of intervals if you don't already know:

9 - the beginning interval = the inversion.

major -} minor

minor -} major

perfect -} perfect

(double) augmented -} (double) diminished

(double) diminished -} (double) augmented

tritone -} tritone

example:

D Major 3rd (D/F#)

9-3=6

major -} minor

D Major 3rd = F# Minor 6th

9 - the beginning interval = the inversion.

major -} minor

minor -} major

perfect -} perfect

(double) augmented -} (double) diminished

(double) diminished -} (double) augmented

tritone -} tritone

example:

D Major 3rd (D/F#)

9-3=6

major -} minor

D Major 3rd = F# Minor 6th

What FP said.

If you want to be specific, I guess you can say "descending Perfect fourth" or something, but it's really not necessary.

#9

Quickie answer - an interval is thedistancebetween notes

Not

*exactly*, since we use ordinal counting with (not from) the reference note.
