Dmin with the counterbass of G..gets you the Bminflat5....an easy natural fingering in some songs ..all efforts are worth it in the end...and minflat5's are essential ammunition in my shooters....

As far as Hohner is concerned, when they made 5 rows they made them specifically so that those 7 chords would be dual purpose. Here is a diagram from a 1937 catalogue:

Wonderful approach....ive been dabbling with Chet Bakers Lets Get Lost for years and never managed to get a decent left hand as the first few bars have that change in and real difficult to get up to speed with big leaps....your solution has opened up the score....many thanks...JeffJetton post_id=61948 time=1534184402 user_id=1774 said:But if you did play the B-7(b5) the way its normally played (counterbass of G plus Dm chord), then you can use a favorite trick of mine: Play the E7 as E (the counterbass of C) plus the F dim button.
I like this for three reasons:
- Its easier to move to from the B-7(b5)
- It actually winds up creating a E7(b9) chord, which almost always sounds great in that minor-key context
- It is then easy to move to what is frequently the next chord: A-7, played as A (counter bass of F) plus C major chord. (Although its still no biggie to decide to hop over to the regular Am chord if you wanted... perhaps combined with the A dim button to create an Am6!)

There are only three different diminished seventh chords. This can be easily demonstrated by playing sequential four note diminished seventh chords (consisting of root, minor 3rd, minor 5th and 6th) on a keyboard while moving up the chromatic scale. Begin by playing the C diminished seventh chord. As you move up chromatically you will produce different chords at C, C#, and D, but when you reach Eb you will find that that chord uses the same note components which were used on the C diminished seventh (a different inversion but the same notes) and those three chords will then be continuously repeated over and over while moving up the chromatic scale. So there are actually just three different note combinations that make up the twelve different diminished seventh chords. To make the point in a different way: (1) C, Eb, F#, and A diminished seventh chords are all different inversions of the same chord, (2) C#, E, G, and Bb are likewise the same, and (3)D, F, Ab and B make up the third group of identical chords.
So, to address our diminished chord substitution question, here’s the reality: if your accordion has no diminished seventh row on the bass side but does happen to have voicing which omits the root from its seventh chords, any seventh chord button can be substituted for any one of four different diminished seventh chords. C7 will work for C#dim, Edim, Gdim or Bbdim; F7 will work for F#dim, Adim, Cdim or Ebdim, and G7 will work for Abdim, Bdim, Ddim and Fdim … etc., etc. BUT, if your accordion’s seventh chords include the root, you’re out of luck and none of your buttons will be compatible with any diminished seventh chord, so you’ll need to create your own diminished chords by playing appropriate single bass (or treble) notes.
