Theory question

Recommended Posts

In sound and music class my teacher calls the minor 3rd of a Cmajor scale E and G. Is this correct? (The teacher is kind of a moron.) I want to say that C to Eb would be the minor 3rd, but I suppose that is for Cminor. I also considered the fact that A is the relative minor of Cmajor. Help anyone?

Right... You can't say THE minor 3rd in a C-major scale is E to G, because D to F and A to C are also minor 3rds. You could say that the minor 3rd in a C-major CHORD is E to G though.

Hmm...maybe that's what he meant. The whole purpose was to demostrate the difference in frequency is a ratio (about 5/4 for a major third; 6/5 for a minor third, in just intonation, different for equal tempered). So basically my teacher should stick to liquid crystal research and cram the music theory up his a$$?!

If this is a college course, go along with your teacher, he's giving you a mark.

 

In a C major scale D-F, E-G, A-C, B-D are minor thirds. C to Eb is a minor third in a C minor scale. In a C major chord E to G is a minor third.

This is one of the confusing things about traditional terms in music analysis.

Frequently people will use a term in one sense but the person hearing the term will take it in another connotation.

The terms diminished & augmented are slightly more precise when discussing intervallic relations but many also use the term minor when discussing 3rds even, as here, when it might not apply to the span between the tonic & scalar 3rd.

This was really confusing to me when trying to learn at early stages; different speakers/writers would use the same terms in different ways, sometimes consistently, sometimes not.

It's even worse when slipping between simple intervals & harmonic/chordal relationships [where all the same terms (major, minor, diminished, augmented) really carry their greatest connotations].

 

This is why I regularly suggest that the terms above be reserved for chords & that the appellations sharped or flatted be used for intervals.

A "flatted 3rd" is a flatted 3rd wherever in the octave it lies & there's no mistaking that for a minor key harmony. Similarly, when the term "diminished" is reserved for a chord type & "flatted 3rd" or "flatted 5th" is used for intervals, there's no confusing the two meanings.

 

Some, unfamiliar with this style may still wonder what you mean but they're more likely to ask, if that's the case, than to presume that they know which sense you're using the term "minor", etc.

d - I know what you mean. It can get confusing. But since that's how those chords actually got their name it kind of makes sense. I don't have a problem with it generally. I'll specify and say this is a diminshed interval. Or if we're talking about intervals saying, "Oh no. It's diminished." But in the real world I'd just more than likely say it's a flatted 3rd or flat 5 or 6 or 3rd or flat 4th. Diminished is a very wierd interval.

All the best,

Of course it's traditional in theory analyses to use the terms augmented, etc., for the harmonic constructs not just for the intervals but as we realize, it's confusing---& not just for neophytes.

 

I think the same problem exists for the use of chord nomenclature. Once it took me a half-hour (which I'll never get...etc. :rolleyes: ) to find that a reference to a "chord of the minor 7th" was intended to name a chord with a major 3rd but a "minor", that is, flatted, 7th.

 

Hence my current insistence on the use of #& b rather than the conventional terms.

As Revoload points out, it's too easy to misconstrue the connotation.

I don't know his EXACT wording, so I really can't make any judgements here.

Sorry. I really don't like the professor.

Anyway, thanks for the help guys. Now I have to go study my mass media for the midterm. FUN!!! :freak::rolleyes:

Actually sounds like you study some pretty interesting subjects! You could be a lot worse off... I studied music in high-school and a couple of years in college. I can't imagine myself studying something else at that time. Now I'm actually interested in studying math, physics, computer science, graphic desgin, web design etc... All kinds of things.

 

I'll have to finish that Bachelor in music first though.

I have some interesting classes. I would be a little more excited about this Sound and Music 1240 class if the professor wasn't such a moron. I'm studying to be a journalist, so I need a large variety of classes.
Shut up and play.
