I was reading a book (Murat Yakin's Starter's Guide to Music Theory and Analysis), and I came to this part, which I think is incorrect. It mentions that the melodic minor scale has only one minor chord (the i chord), and that this is the reason why we can't identify the melodic minor as a minor tonality, while the the notation clearly defines the ii chord as minor...is this a mistake or is there something that I am not getting? enter image description here

    For future reference, I added the name of the book in your first sentence. And may I helpfully suggest finding a different book to read? :-) – Richard Jun 15 '17 at 18:21
  • If you please, suggest more advanced books....thanks – Jaafar Jumaa Jun 16 '17 at 8:35
  • The book appears to be self-published. But the author has credentials. Nonetheless, I haven't a clue what he's talking about, and can't see any way to 'find the truth in it' by adjusting any simple misprint or mis-translation. "Murat Yakin - Born in 1977, in Ankara, Turkey. He holds a DMA degree in composition from University of Memphis, and an MM degree from Istanbul Technical University, Center for Advanced Studies in Music. He is currently teaching composition, music theory, and 20th century music classes at Baskent University State Conservatory as an associate professor of composition." – Laurence Payne Jun 16 '17 at 11:58
  • I have played the harmonic and melodic minors along with natural minor and to be honest, I prefer natural minor be used in all keys. But I can understand using harmonic minor for keys with sharps. Flats though, to me means natural minor is required, at least for the keys from D minor to Bb minor. Melodic minor though sounds very wrong to me in every key. In the example of C minor(which I commonly use to illustrate the difference), it sounds like C major + Eb rather than C minor - Bb - Ab. Both the subdominant and the dominant are major in melodic minor, the Tonic is the only unaltered chord. – Caters Aug 2 '18 at 2:59

Yes, B, D, F# looks like a minor triad to me! c seems to be merely a misprint for a. If he intends to 'go over the choices one by one' he wouldn't start with the last one!

But a contains three minor triads. b and c contain two each. Let's assume he isn't simply an idiot, he must be failing to explain his meaning clearly. I get the impression English isn't his first language.

What's the source? Apart from the obvious errors, he seems to be falling into the usual trap of thinking a scale or mode is a restriction rather than a base.

  • Laurence, I don't think I see which misprint your'e referring to. We could change the highlighted text to read: "Let's go over the choices one by one. a does not seem to be the right choice, because the only minor chord it has is the i chord." Isn't this statement still incorrect? – jdjazz Jun 16 '17 at 14:08
  • Yup. It's ALL incorrect. Two hours before you posted your comment I edited my answer to make that clearer. – Laurence Payne Jun 16 '17 at 15:02
  • Thanks for the clarification! What I'm specifically confused by is why c would be a misprint if swapping in a makes the statement even more incorrect (per your edited comment). The edited statement that he's not expressing his meaning clearly makes a lot of sense to me, but I'm stuck on the first statement that c is merely a misprint for a. – jdjazz Jun 16 '17 at 15:29
  • Because he said he was going to 'go over the choices one by one'. That implies starting with the first one. Not the main point, but support for my theory that the whole page is a bit of a mind-fart :-) – Laurence Payne Jun 16 '17 at 15:55

The highlighted statement is incorrect for a couple of reasons. As you've correctly said, scale c contains two unaltered minor triads. Here's the full list:

  • scale a (natural minor): contains A min triad, D min triad, and E min triad
  • scale b (harmonic minor): contains A min triad and D min triad
  • scale c (melodic minor): contains A min triad B min triad

Setting that smaller error aside, there are a couple of deeper issues I have with the highlighted analysis.

First, the quality of a chord depends on more than just the triad, and because the author ignores the other notes, I think he/she has mislabeled some of those chords. I'll consider A melodic minor (scale c). The modes of A melodic minor are well known:

https://i2.wp.com/theoryandchanges.com/wp-content/uploads/2015/09/Modes-of-A-mel-minor-scale.png

There is significant contrast between the list I've included above and the source you've included in your post. For example, I'm much more inclined to call the vi chord vi min ♭5 than vi dim. In fact, the question "How many of these modes are minor" is a bit ambiguous. Two of the modes from above contain unaltered minor triads (im∆7 and iim♭2), but if you consider Locrian to be min♭5, then there is certainly a third altered minor chord (the vi chord) and maybe even a fourth minor mode (the vii chord). This ambiguity is problematic for the source you've included, because it seems like his/her argument relies on a sharp distinction between "minor" and "not minor"--at least, the author needs these two categories to be distinct enough that he/she can simply count up how many are in each category. I don't think that sharply defined boundary exists.

Another issue I see is that the author hasn't correctly identified why a given minor scale might be harder to distinguish from a major scale, or why a different minor scale might be easier to distinguish from a major scale. The best way to do this analysis is to compare each minor scale to the major scale. This contrasts with the author's approach of comparing the minor scales to each other, which I think is much less useful. When we compare each minor scale (a, b, and c) to A major, what do we find? Scale c (A melodic minor) differs from A major by only one note: the third (C vs. C♯. This, in my opinion, is the support the author is looking for when he/she states "it is hard[er] for the ear to recognize [scale c] as a minor tonality."

Note: in the instance where a scale might have an alternative descending form, I'm referring only to the ascending form, for simplicity.

    Natural minor contains three minor triads - i, iv and v. So does melodic, looking at classical descending, which is natural minor again. – Tim Jun 15 '17 at 16:48
  • Thanks @Tim for catching this error. I've edited to fix this. I've also added a statement addressing your good point about ascending vs. descending, to clarify the discussion. What are your thoughts on the proposal to use 'number of minor triads' as an indicator for 'how minor' a scale sounds? – jdjazz Jun 15 '17 at 17:18

    I have none. The 'minorness' of a piece, or even a scale, is squarely down to the root triad, in my ears. Dorian, Phrygian are both minor, due to home being a minor triad. It's where it ends, and usually starts. The statement is 'This is minor'. The raised leading note/tone often pushes towards 'This is definitely minor', but even without it, the minority is there... – Tim Jun 15 '17 at 17:40

Classically speaking (my interpretation of Common Practice Period harmony), the statement isn't really correct. Keys have associated chords and scales; scales (per se) do not have chords. (I'm not familiar enough with jazz or pop theory to discuss the terminology used there. Perhaps the original question arises in those contexts.)

The minor mode has two mutable tones, 6 and 7. There are various common usages of these. Either form of the note (like A or Ab in C minor) is usually considered diatonic. About the only unusual combination in a melody is the "natural" (lowered) step 7 and the raised step 6 (like G-A-Bb-C or similar), but I it may occur. Some of the chords using the raised 7 are common: V, V7, vii0, vii07. Those using the raised 6 are less common although ii, ii7 and even IV do occur; more rarely one gets II or II7. The augmented III+ is rare but still occurs if the voice leading requires it.

Common are i, iv, v, (but V in cadential patterns), III, VII, VI, ii0, ii06, and vii0.

The three forms of the minor scale come from arranging melodic (and harmonic) patterns in order of pitch. There are a few common usages of natural or raised steps but exceptions are common.

With tonic harmony (i chords), melodies often use the raised 6 and 7 when ascending and the natural 6 and 6 when descending. With subdominant harmony (iv chords), both the 6 and 7 are predominately used in their natural state. With dominant harmony (V or vii0 chords), the raised notes are common. The idea is the provide a half-step approach to the root (step 8 actually) both melodically and harmonically while avoiding the augmented 2nd between 6 and raised 7. The pattern 4,5,6b,7 isn't uncommon as it outlines a V9 chord. In instrumental music, usage is more diverse. Mozart and Beethoven often use the "harmonic" scale in ascending and descending passages in instrumental music.
