Cm7b5, or C/o7?

[Christian Miller]

I thought beboppers called it min6

I wish I still were a lad. It was so much easier just knowing C and G7.

On the other hand, Musescore has an easily-typed slashed zero: just type a zero, and then exit the chord.

The slashed 0, or ø , is what is sometimes used for half-diminished.

A theta, on the other hand, is a zero with a horizontal line, which I have never seen depicting a half-diminished chord.

And even though I copied and pasted these things from the internet, neither the slashed-zero nor the theta show up in this post...

I always thought it was a slashed ° ...aka, the degree symbol. But even before computer notation fonts, I always saw it written as a symmetrical circle, not an oval like the numeral 0.

[charleyrich99]

Which do you write? Minor7flat5, or half dim7? And more importantly, why?

Half diminished.
That's how I learned it from my teacher at the time, Joe Monk. Today, it takes up less horizontal space in Finale.

[charleyrich99]

How about Maj7, M7, or /\7?

I use the triangle for Maj7. Again, this takes up less horizontal space allowing a larger font and greater read ability.

[ragman1]

Use whatever you want as long as other people understand it. Who cares?

I like the triangle too and not too tiny. In fact, I make a point of increasing the size of the chord symbols as far as possible on every chart. I am one, and play with, old guys.

I like the little m for minor. I don't like the dash "-" for minor.

I don't want M and m on the same score, especially not handwritten.

I like the superscript numbers to be appropriately displaced.

At least we agree on something!

Yes you are quite right, I am embarrassed as a sometime person who did maths.

The problem with the triangle for major is it’s unclear whether this refers to a triad or a major seventh chord.

as we're talking maths the 1/2 dim symbol is more like the letter phi.
ps I have always considered the triangle to represent major 7th.

Yes, it stinks when the M & m's melt on your score, not in your mouth.

I think it's best to specify that is a major 7th chord, say C^7, even though it implies that, i.e., C is written for the triad and you don't see C^6, C^6/9, etc.

That’s what I do but I’m sure someone somewhere will regard this as wrong

Everybody's wrong about something.

Just strive for clarity for the reader. If you need to, put a little disambiguating symbol table at the bottom of the score.

One of the reasons I like it. (And not just for Finale.)

Please check me on this...

Assuming:

3 is "major"
b3 is "minor"
b5 is "flat five"
#5 is "augmented"
b3 b5 is "diminished"
7 is "major seventh"
b7 is "seventh" (not "flat seven") and "dominant seventh"

These names are coherent and consistent...

1 3 5 7 major seventh
1 b3 5 7 minor major seventh
1 3 #5 7 augmented major seventh
1 3 b5 7 major seventh flat five
1 b3 b5 7 diminished major seventh
1 3 5 b7 dominant seventh
1 b3 5 b7 minor seventh
1 3 #5 b7 augmented seventh
1 3 b5 b7 dominant seventh flat five
1 b3 b5 b7 minor seventh flat five

These chords are "misnamed"...

1 b3 b5 b7 half-diminished seventh
(should be "diminished seventh"
or "minor seventh flat five")

1 b3 b5 bb7 diminished seventh
(should be "diminished flat seventh"
or minor flat seventh flat five")

bb7 is the diminished seventh. there is no such thing as a flat seventh. sevenths are imperfect intervals. they exist as major, minor, diminished, augmented.

To how many chord tones does the word "diminished" apply in the chord called "diminished seventh"?

Is there such a thing as an augmented 7th?

P.S. - Web search answer was (below), don't know why you wouldn't call it an octave.


"In classical music from Western culture, an augmented seventh is an interval produced by widening a major seventh by a chromatic semitone."

Theoretical construct. It might be useful to notate something that way in the same way it's occasionally useful to notate an Fb or B#.

Probably not often.

There’s such a thing as a diminished octave too

Spelling is important in classical theory

Most obvious example is the chord of the augmented six, which jazzers write as “dominant seventh” chord (and lets not get into the confusion about dominant sevenths haha.)
