-When octaves are specified in absolute mode it is easy to
-accidentally put a pitch in the wrong octave. Relative octave
-mode reduces these errors since most of the time it is not
-necessary to indicate any octaves at all. Furthermore, in
-absolute mode a single mistake may be difficult to spot, while in
-relative mode a single error puts the rest of the piece off by one
-octave.
+Absolute octave entry requires specifying the octave for every
+single note. Relative octave entry, in contrast, specifies each
+octave in relation to the last note: changing one note's octave
+will affect all of the following notes.
+
+Relative note mode has to be entered explicitly using the
+@code{\relative} command:
@example
\relative @var{startpitch} @var{musicexpr}
@item
The pitch of the first note is relative to
@code{@var{startpitch}}. @code{@var{startpitch}} is specified in
-absolute octave mode, and it is recommended that it be a octave of
-@code{c}.
+absolute octave mode. Which choices are meaningful?
+
+@table @asis
+@item an octave of @code{c}
+Identifying middle C with @code{c'} is quite basic, so finding
+octaves of @code{c} tends to be straightforward. If your music
+starts with @code{gis} above @code{c'''}, you'd write something
+like @code{\relative c''' @{ gis' @dots{} @}}
+
+@item an octave of the first note inside
+Writing @code{\relative gis''' @{ gis @dots{} @}} makes it easy to
+determine the absolute pitch of the first note inside.
+
+@item no explicit starting pitch
+This (namely writing @code{\relative @{ gis''' @dots{} @}}) can be
+viewed as a compact version of the previous option: the first note
+inside is written in absolute pitch itself. This happens to be
+equivalent to choosing @code{f} as the reference pitch.
+@end table
+
+The documentation will usually employ the first option.

-@c DEPRECATED
-If no @code{@var{startpitch}} is specified for @code{\relative},
-then@tie{}@code{c'} is assumed. However, this is a deprecated
-option and may disappear in future versions, so its use is
-discouraged.
