-It is very common for one voice to double some of the music from
-another voice. For example, the first and second violins may play the
-same notes during a passage of music. In LilyPond this is accomplished
-by letting one voice @emph{quote} the other voice without having to
-re-enter it.
+It is very common for one voice to use the same notes as those from
+another voice. For example, first and second violins playing the same
+phrase during a particular passage of the music. This is done by
+letting one voice @emph{quote} the other, without having to re-enter the
+music all over again for the second voice.
-Before a part can be quoted, the @code{\addQuote} command must be used
-to initialize the quoted fragment. This command must be used in the
-toplevel scope. The first argument is an identifying string, and the
-second is a music expression:
-
-@example
-flute = \relative c'' @{
- a4 gis g gis
-@}
-\addQuote "flute" @{ \flute @}
-@end example
+The @code{\addQuote} command, used in the top level scope, defines a
+stream of music from which fragments can be quoted.
The @code{\quoteDuring} command is used to indicate the point where the
quotation begins. It is followed by two arguments: the name of the
quoted voice, as defined with @code{\addQuote}, and a music expression
-that indicates the duration of the quote, usually spacer rests or
-multi-measure rests. The corresponding music (including all articulations,
-dynamics, markup, etc.) from the quoted voice is inserted into the music
-expression:
+for the duration of the quote.

+fluteNotes = \relative c'' {

-If the music expression used for @code{\quoteDuring} contains
-anything but a spacer rest or multi-measure rest, a polyphonic
-situation is created, which is often not desirable:
+If the music expression used in @code{\quoteDuring} contains notes
+instead of spacer or multimeasure rests then the quote will appear as
+polyphony and may produce unexpected results.

-Quotations recognize instrument transposition settings for both
-the source and target instruments if the @code{\transposition}
-command is used. For details about @code{\transposition}, see
-@ref{Instrument transpositions}.
+The @code{\quoteDuring} command uses the @code{\transposition} settings
+of both quoted and quoting parts to produce notes for the quoting part
+that have the same sounding pitch as those in the quoted part.

-It is possible to tag quotations with unique names in order to
-process them in different ways. For details about this procedure,
-see @ref{Using tags}.
+\addQuote "clarinet" { \clarinetNotes }
-It is also possible to adjust which objects from the original voice are quoted
-by changing the @code{quotedEventTypes} property. By default, its value is
-@code{#'(StreamEvent)}, which means that everything is quoted. Setting it
-to e.g. @code{#'(note-event rest-event tie-event)} causes lilypond to quote
-only notes, rests and ties, but no articulations, markup or dynamics.
