If additional control is needed over the individual staves, they
can be created manually with the names @code{"up"} and
@code{"down"}. The @code{\autochange} command will then switch
-its voice between the existing staves. For example, this is
-necessary to place a key signature in the lower staff:
+its voice between the existing staves.

+
+Harps have seven strings per octave that may be sounded at the natural,
+flattened, or sharpened pitch. In lever harps, each string is adjusted
+individually, but in pedal harps every string with the same pitch name
+is controlled by a single pedal. From the player's left to right, the
+pedals are D, C, and B on the left and E, F, G, and A on the right.
+The position of the pedals may be indicated with text marks:
+
+@lilypond[quote,verbatim,relative=2]
+\textLengthOn
+cis1_\markup \concat \vcenter { [D \flat C \sharp B|E \sharp F \sharp G A \flat] }
+c!1_\markup \concat \vcenter {[ C \natural ]}
+@end lilypond
+
+or pedal diagrams:

+@lilypond[quote,verbatim,relative=2]
+\textLengthOn
+cis1_\markup { \harp-pedal #"^v-|vv-^" }
+c!1_\markup { \harp-pedal #"^o--|vv-^" }
+@end lilypond
+
+The @code{\harp-pedal} command accepts a string of characters, where
+@code{^} is the highest pedal position (flattened pitch), @code{-} is
+the middle pedal postion (natural pitch), @code{v} is the lowest pedal
+position (sharpened pitch), and @code{|} is the divider. A prefixed
+@code{o} will circle the following pedal symbol.
