+Because transposing changes both note names and octaves relativizing
+transposed music doesn't make any sense. If you want to transpose
+relative music, do code(\transpose var(pitch) \relative var(pitch)
+var(music)), i.e., first enter the music in relative mode, and then
+transpose it by prepending the code(\transpose) keyword.
+code(\relative var(pitch) \transpose var(pitch)) has no effect.
+
+For the same reason the first code(\relative) in code(\relative
+var(pitch1) \relative var(pitch2) var(music)) has no effect.
