\chapter{Smaller (or Larger) Notes in Normal-Sized Staves}
Here we describe how to change the size of note symbols without changing the
size of the staff itself. Changing overall staff size will be treated in
Chapter~\ref{staffspacing}.
\section{Arbitrary sequences of notes}
Written-out ornaments and \itxem{cadenzas} are usually typeset with
smaller notes and spacing than normal. The smaller \ital{size} can be
initiated anywhere inside a \verb|\notes| group by stating
\keyindex{smallnotesize} or \keyindex{tinynotesize}. Normal note size is then
restored by \keyindex{normalnotesize} or simply by terminating the
\verb|notes| group and starting another. Smaller \ital{spacing} must also be
explicitly indicated, usually by redefining \verb|\noteskip| in some way.
As an example, this excerpt, from the beginning
of the Aria of the ``Creation'' by Joseph {\sc Haydn})\index{Haydn, J.@{\sc
Haydn, J.}},
\section{Grace notes}
Grace notes are a special case of small and tiny notes, namely single-stemmed
eighth notes with a diagonal slash through the flag. To enable this, there
are the macros \keyindex{grcu}\pitchp\ and \keyindex{grcl}\pitchp, which by
themselves would
produce normal-sized eighth notes with a slash. They should be used along
with the note size reduction macros and spacing reduction macros just
discussed. In addition, chordal grace notes can be built as in the following
example:
