Ok, I found
http://lilypond.org/doc/v2.20/Documentation/extending/markup-construction-in-scheme

That lead me to:

#(define (bassNote grob)
   "mark chord as single bass note"
   (let* (
  ; Get current text
  (currentText (ly:grob-property grob 'text))
  (markedText (markup #:small #:fraction "" currentText )))
 ; Store the marked text back
 (ly:grob-set-property! grob 'text markedText)
 )
   ; and print it
   (ly:text-interface::print grob))

% bnC = bass note "chord"
bnC = \once \override ChordNames.ChordName.stencil = #bassNote

Now my syntax is: \bnC 4 \bnC 

A bit verbose, but since I need it only for a few songs, it’s good enough.

Ah, thanks for the hint.

I found a snippet to add brackets to a chord:

#(define (addBrackets grob)
   "Place brackets around a text object."
   (let* (
  ; Get current text
  (currentText (ly:grob-property grob 'text))
  (bracketedText (markup "(" currentText ")")))
 ; Store the bracketed text back
 (ly:grob-set-property! grob 'text bracketedText)
 )
   ; and print it
   (ly:text-interface::print grob))

% opC = optional chord (in brackets)
opC = \once \override ChordNames.ChordName.stencil = #addBrackets


Now, how can I use markup like \tiny or \circle within that (markup ...) ?

Best, Hraban

Try  .  You'll still need to fiddle with the chord naming function.
