Within a full score the
musician will find all parts of a piece notated on their own stave with proper
transpositions,
expressions,
dynamics, etc.
Some full scores are the more literal full scores with each individual part (
Horn I, Horn II, Horn III, Horn IV) set on its own staff. Others feature parts combined on a single staff where possible to save
space,
paper, and to make the score more
legible.
When parts are combined and the total number of parts for an
instrumental section is
divisible by two, the parts are usually combined
I and
III,
II and
IV. This is because parts I and II are often independant of each other with III and IV acting as support and harmonization for I and II, respectively.
Otherwise, all parts are found on a single stave or I is alloted its own stave while II and III are
combined beneath it. Any time there are more than four parts per section the combination of I and III, II and IV will be found with V or V and VI on their own staff. Anything that features more than six parts per section should be
reconsidered, unless it is a
specialty or
experimental piece.
