```
This is not a problem of #{ ... #}. It is actually a problem of \$music. You'll get the same result if you say
```zap = { <c e g>4 ~ q }
\relative c' \zap

```
The reason is that when music passes through a MUSIC_IDENTIFIER (and \$ works by creating such an identifier), Lilypond does a deep copy of the structure.
```
```
The repeated chord relative callback in lily/music-sequence.cc, however, works by looking up the pitch of the 'original-chord that it already assumes to be relativated. Unfortunately, after a deep copy, the 'original-chord is no longer the same as the original chord, since the deep copying made _separate_ copies of the original chord, and the original-chord field of the RepeatedChord.
```
```
As a consequence, after copying the original-chord field does not point to a relativated chord, but to a copy that has been made _before_ relativizing and that is no longer associated with the relativized chord.
