@subheading Offsets
Two-dimensional offsets (X and Y coordinates) are stored as @code{pairs}.
-The @code{cdr} of the offset is the X coordinate, and the @code{cdr} is
+The @code{car} of the offset is the X coordinate, and the @code{cdr} is
the Y coordinate.

So in our function, we need to clone this expression (so that we
-have two notes to build the sequence), add @code{SlurEvents} to the
+have two notes to build the sequence), add a @code{SlurEvent} to the
@code{'elements} property of each one, and finally make a
@code{SequentialMusic} with the two @code{EventChords}.
