Differentiate between contexts

[sir.teddy.the.first]

Hi all,

please consider the following snippet:

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\version "2.20.0"

 

\score {

  <<

    \new ChordNames = "chrdsI" \chordmode { \set chordChanges = ##t e1:min |
1 | 1 | 1 | 1 | 1 | 1 | 1 | }

    \new Staff \relative c'{ c1 d e f g a b c | }

    

    \new ChordNames = "chrdsII" \chordmode { \set chordChanges = ##t a1:min
| 1 | 1 | 1 | 1 | 1 | 1 | 1 | }

    \new Staff \relative c'{ c1 | 1 | 1 | 1 | \set ChordNames.chordChanges =
##f 1 | 1 | 1 | 1 | }

  >>

}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%

 

The command "\set ChrodNames.chordchanges = ##f" in the second staff always
applies to the first ChordNames-Context.

How can I explicitly reference the second ChordNames-Context, preferably by
name?

 

Thanks in advance
