Great thomasso. I learned something today. I never knew that the diminished symbol meant zero root, or no root. I had never heard of that before. Thanks

Musical Proofs. Reminds me of Geometry, Trigonometry, and Calculus proofs, and I like it!

Short answer: "Yes."

again, blown away by the simplicity and clarity..... ( º ) = 'No Root'.

Great video. I would like to share another angle: I like to organize a key in the circle of thirds like C E G B D F A C or more general like 1 3 5 7 2 4 6 1. On paper one could draw an actual circle and add a label to the edges which distinguishes minor from major thirds. One would find that they alternate except for one spot where two minor thirds come in a row. I find it beautiful that this very compact representation alows so many insights about the major tonality and the relationship between its diatonic chords. Things it directly shows: - every major chord has its relative minor chord and the union of their notes give the minor 7 or 6th (major) chord - there are two major chords followed by a minor chord, thus there are two major 7th chords - as for the topic of the video: there is one major chord followed by the dim chord, together they form the dom7 chord I guess there are many more relationships which can be grasped easily by looking at this organization of the notes. The circle of thirds is also great for practicing chord inversions: If one goes through the chords in this order only one note changes per chord change and the nearest inversions just change by "one degree" in a consistent way, this could be also added to edges of the circle...

I use the progression E7 C#7 G7 Bb7 in 12-bar blues progression format and migrate to Fdim, Ddim, G#dim, Bdim. Soloing over that is mind expanding.

This vid is a revelation to me, particularly that zero!

Excellent explanation - and it’s rounding out my basic knowledge of chord substitution - which should be very helpful when trying to sound interesting when playing the blues - as well as fumbling through some basic jazz! PS - I've just thought back to 'Autumn Leaves' - and there's a C# diminished in there that's part of a ii-V-I - which is sort of a classic example of how to do it!

Shit!!! B° means zero root! I never put that together. I learn something new every day. Thanks!

I am still amazed by theory when I finally understand it because it is explained so well! So much that you could apply this theory on any instrument, even drums and triangle for sure! Thx dear teacher

Do you want a dominant chord or diminished? Me: Yes

I used a Bm7b5 to go from A to Am...is that the same principle but borrowed from the relative key

Isnt this the same for other chords tho? Like the 1 and 3 chord share the same notes minus the root in the 1.

Isn't this just a special case of the tritone substitution?

Νόστιμο !

if you treat the root of the diminished chord as a major third, by adding the 6th degree of locrian as a bass note. Source: I'm guessing.

What is all this? Then likewise, if you are removing the root from a minor 7th chord, it becomes a major chord. Whats the point of all these word games? Why not just name the chords from the root and never not from the root. What is this no root business. How does it help? It seems like "oh look! 2+5+5+2+3+2 = 3+4+4+4+3+1. Wow....."

Scale degree 5 and 7 are dominant chords, it references harmonic function. They share notes, but the root of a 5 chord is 5 and the root of a 7 chord is 7. Stop spreading lies.
