+@node Input modes
+@subsection Input modes
+
+The way in which the notation contained within an input file is
+interpreted is determined by the current input mode.
+
+@strong{Chord mode}
+
+This is activated with the @code{\chordmode} command, and causes
+input to be interpreted with the syntax of chord notation, see
+@ref{Chord notation}. Chords are rendered as notes on a staff.
+
+Chord mode is also activated with the @code{\chords} command.
+This also creates a new @code{ChordNames} context and
+causes the following input to be interpreted with the syntax of
+chord notation and rendered as chord names in the @code{ChordNames}
+context, see @ref{Printing chord names}.
+
+@strong{Drum mode}
+
+This is activated with the @code{\drummode} command, and causes
+input to be interpreted with the syntax of drum notation, see
+@ref{Basic percussion notation}.
+
+Drum mode is also activated with the @code{\drums} command.
+This also creates a new @code{DrumStaff} context and causes the
+following input to be interpreted with the syntax of drum notation
+and rendered as drum symbols on a drum staff, see @ref{Basic
+percussion notation}.
+
+@strong{Figure mode}
+
+This is activated with the @code{\figuremode} command, and causes
+input to be interpreted with the syntax of figured bass, see
+@ref{Entering figured bass}.
+
+Figure mode is also activated with the @code{\figures} command.
+This also creates a new @code{FiguredBass} context and causes the
+following input to be interpreted with the figured bass syntax
+and rendered as figured bass symbols in the @code{FiguredBass}
+context, see @ref{Introduction to figured bass}.
+
+@strong{Fret and tab modes}
+
+There are no special input modes for entering fret and tab symbols.
+
+To create tab diagrams, enter notes or chords in note mode and
+render them in a @code{TabStaff} context, see
+@ref{Default tablatures}.
+
+To create fret diagrams above a staff, enter them as markup
+above the notes using the @code{\fret-diagram} command, see
+@ref{Fret diagrams}.
+
+@strong{Lyrics mode}
+
+This is activated with the @code{\lyricmode} command, and causes
+input to be interpreted as lyric syllables with optional durations
+and associated lyric modifiers, see @ref{Vocal music}.
+
+Lyric mode is also activated with the @code{\addlyrics} command.
+This also creates a new @code{Lyrics} context and an implicit
+@code{\lyricsto} command which associates the following lyrics
+with the preceding music.
+
+@strong{Markup mode}
+
+This is activated with the @code{\markup} command, and causes
+input to be interpreted with the syntax of markup, see
+@ref{Text markup commands}.
+
+@c silly work-around for texinfo broken-ness
+@c (@strong{Note...} causes a spurious cross-reference in Info)
+@b{Note mode}
+
+This is the default mode or it may be activated with the
+@code{\notemode} command. Input is interpreted as pitches,
+durations, markup, etc and typeset as musical notation on a staff.
+
+It is not normally necessary to specify note mode explicitly, but
+it may be useful to do so in certain situations, for example if you
+are in lyric mode, chord mode or any other mode and want to insert
+something that only can be done with note mode syntax.
+
+For example, to indicate dynamic markings for the verses of a
+choral pieces it is necessary to enter note mode to interpret
+the markings:
+
+@lilypond[verbatim,relative=2,quote]
+{ c4 c4 c4 c4 }
+\addlyrics {
+ \notemode{\set stanza = \markup{ \dynamic f 1. } }
+ To be sung loudly
+}
+\addlyrics {
+ \notemode{\set stanza = \markup{ \dynamic p 2. } }
+ To be sung quietly
+}
+@end lilypond
+
+
+
+@node Direction and placement
+@subsection Direction and placement
+
+In typesetting music the direction and placement of many items is
+a matter of choice. For example, the stems of notes can
+be directed up or down; lyrics, dynamics, and other expressive
+marks may be placed above or below the staff; text may be aligned
+left, right or center; etc. Most of these choices may be left to
+be determined automatically by LilyPond, but in some cases it may
+be desirable to force a particular direction or placement.
+
+@strong{Default actions}
+
+By default some directions are always up or always down (e.g.
+dynamics or fermata), while other things can alternate between
+up or down based on the stem direction (like slurs or accents).
+
+@c TODO Add table showing these
+
+@strong{Context layout}
+
+Contexts are positioned in a system from top to bottom in the
+order in which they are encountered. Note, however, that a
+context will be created implicitly if a command is encountered
+when there is no suitable context available to contain it.
+
+@c TODO Add example ?
+
+The default order in which contexts are laid out can be changed,
+see @ref{Aligning contexts}
+
+@strong{Articulation direction indicators}
+
+When adding articulations to notes the direction indicator,
+@code{^} (meaning @qq{up}), @code{_} (meaning @qq{down}) or
+@code{-} (meaning @qq{use default direction}), can usually be
+omitted, in which case @code{-} is assumed. But a direction
+indicator is @strong{always} required before
+
+@itemize
+@item @code{\tweak} commands
+@item @code{\markup} commands
+@item @code{\tag} commands
+@item string markups, e.g. -"string"
+@item fingering instructions, e.g. @code{-1}
+@item articulation shortcuts, e.g. @code{-.}, @code{->}, @code{--}
+@end itemize
+
+@strong{The direction property}
+
+The position or direction of many layout objects is controlled
+by the @code{direction} property.
+
+The value of the @code{direction} property may be
+set to @code{1}, meaning @qq{up} or @qq{above}, or to @code{-1},
+meaning @qq{down} or @qq{below}. The symbols @code{UP} and
+@code{DOWN} may be used instead of @code{1} and @code{-1}
+respectively. The default direction may be specified by setting
+@code{direction} to @code{0} or @code{CENTER}. Alternatively,
+in many cases predefined commands
+exist to specify the direction. These are all of the form
+
+@noindent
+@code{\xxxUp}, @code{xxxDown}, @code{xxxNeutral}
+
+@noindent
+where @code{xxxNeutral} means @qq{use the default direction}.
+See @rlearning{Within-staff objects}.
+
+In a few cases, arpeggio being the only common example, the value
+of the @code{direction} property specifies whether the object
+is to be placed to the right or left of the parent object. In
+this case @code{-1} or @code{LEFT} means @qq{to the left} and
+@code{1} or @code{RIGHT} means @qq{to the right}. @code{0}
+or @code{CENTER} means @qq{use the default} direction, as before.
+
+@ignore
+These all have side-axis set to #X

+@node Spanners
+@subsection Spanners
+
+Many objects of musical notation extend over several notes or even
+several bars. Examples are crescendi, trills, tuplet brackets, and
+volta repeat brackets. Such objects are called @qq{spanners}, and
+have special properties to control their appearance and behaviour.
+Some of these properties are common to all spanners; others are
+restricted to a sub-set of the spanners.
