Double Bass Chord Name. Please confirm.

I have a fairly good list but this one is not on it. I have seen the slash used as a Spanish number Seven. Check out the first chord and others. I've concluded that the 7 w/slash signifies Maj7. Variations in this book include ex: Bb-7(with slash) etc.
What say you?
btw. this book came from a friend in Spain.

I haven't seen that specific nomenclature before but based on context, I think that you're right, that C(7 with a dash through it) means C Major 7. It would be very common for that first chord to me a Major chord, either C, C Major 7, C Major 6, C Major 69, or other similar chord. And that's not inconsistent with a Bb-7(with a dash) which could me a Minor chord with a Major 7th instead of a Minor 7th.

Never seen this before but I agree C7 means CMaj7.

Found this online:

Ted uses a slash through 7, 9, and 13 to indicate major 7, major 9, or major 13

Thanks to both of you.

Thanks Wasnex for the link. I will nose around the site. I've had Chord Chemistry sitting on the shelf for years. I better crack it open.

That notation would be very confusing for me, since 7 with a dash is the usual handwriting for 7 in my country.

It's confusing for me as well because the I am used to a dash meaning minor.

minor is (usually) a dash before the "7", not through the "7".

 

[lurk]

Obviously the slash here means M7, but, more interesting to me are the changes here.. Nice! Some not-affected-sounding twists that are pleasing to my ear.

 

[gerry grable]

Just write a M. Why try to reinvent the wheel?

 

[BucketOfFish]

One positive is that it does serve as economy of space within a measure.

I've seen maj7 chord commonly notated that way for at least 25 years. I must exist in an alternate universe or something...

This might make no sense whatsoever but most of those appear to be european numeral "ones". The seven with a slash through it is just that, a seven.

Edited for phone typos

 

[DoubleMIDI]

The slash through the seven is (at least in Europe) common for a handwritten seven to distinguish it from a handwritten one which can look almost the same if written fast or sloppy if there is no slash through the seven.

So, at least from an international point of view, a slash through the seven for a major seven is not a good idea.
I understand it from a space saving point of view, but in my opinion the confusion generated by this has more weight.

Anyway, since it is done, we should know it, so thanks for bringing this topic up here.

Same here. Actually, I had a really hard time figuring out what people were talking about at first because it's just how some people would write a regular dominant 7 chord around here.

Which wat is "that way?"

 

[SAlcott]

If I see a 7 with a slash I assume Major 7 chord and don’t obsess about it.

Right; it's the minorMajor, ascending melodic minor, or some know it as the jazz minor. A fun exercise: extract the modes from the BbmM7 scale, and then from each mode, stack its first, third, fifth and seventh voice (make seventh chords). Then, play these chords on the piano with the sustain pedal and simply listen...

Not a unique definition, even though one can assume you mean Bb melodic minor (ascending).
Other possible scales than Bb mMin I which fit to your chord definition:
Bb hMin I
Bb hMaj IV

Just a hint:
The classical way of using different notes for ascending and descending melodic minor also means a change of the scale from mMin I to aeolian (and probably back). Since in earlier centuries the chord was a triad or dominant seventh or the changing notes in ascending and descending was either not fixed by the definition in the chord for the changing notes or a change from dominant to tonic made an implicit change of the scale in the change of the function.

Well, yes, plainly by my opening sentence: "Right; it's the minorMajor, ascending melodic minor, or some know it as the jazz minor." If you decide to do that exercise btw, these other tonalities will manifest (e.g., altered dominant, whole tone). The whole point that you seemed to have overlooked is simplification for an improvising player, which really was the main objective.
