I’m trying to get the chord name into my head so that my fingers just go there and it’s like I have to count every time.
IMO the trick is to get the functions of the notes per string right. Combined with the voicing "rules" I already mentioned in another thread, the amount of options is shrinking quite a bit (in terms of organisation).
For example, the root could either become the 7th or the ninth. Maj7 is a halftone below, so 7 must be a wholetone. 9th is a wholetone above, so b9 must be a halftone, #9 3 halftones above.
Same goes for the 5th, which could either be altered by itself (b5, #5), so that's self explaining, or it could become 11th or 13th. 11th is a wholetone below, so #11 is a halftone below. 13 is a wholetone above, so b13 is a halftone above.
This is pretty much it for the "extensions" already, you would now only have to additionally cover sus2, sus4 and 6. The former replace the 3rd, the latter replaces the 5th in a plain triad context and the 7th in a 7th-chord context.
And that's pretty much it (with the exception of diminished and augmented chords, but even those could be fitted in if you know the rest already).
