A ''short score'' is a reduction of a work for many instruments to just a few staves. Rather than composing directly in full score, many composers work out some type of short score while they are composing and later expand the complete orchestration. An opera, for instance, may be written first in a short score, then in full score, then reduced to a vocal score for rehearsal. Short scores are often not published; they may be more common for some performance venues (e.g., band) than in others. Because of their preliminary nature, short scores are the principal reference point for those composers wishing to attempt a 'completion' of another's unfinished work (e.g. Movements 2 through 5 of [[Gustav Mahler]]'s [[Symphony No. 10 (Mahler)|10th Symphony]] or the third act of [[Alban Berg]]'s opera ''[[Lulu (opera)|Lulu]]'').

An ''open score'' is a score of a [[Polyphony|polyphonic]] piece showing each voice on a separate staff. In Renaissance or Baroque keyboard pieces, open scores of four staves were sometimes used instead of the more modern convention of one staff per hand.<ref>{{Cite Grove |last=Cochrane |first=Lalage |title=Open score}}</ref> It is also sometimes synonymous with full score (which may have more than one part per staff).

In a ''close score'', all voice parts are represented on the two major staffs (treble and bass staffs).

Scores from the Baroque period (1600–1750) are very often in the form of a [[bass line]] in the bass clef and the melodies played by instrument or sung on an upper stave (or staves) in the treble clef. The bass line typically had figures written above the bass notes indicating which intervals above the bass (e.g., chords) should be played, an approach called ''[[figured bass]]''. The figures indicate which intervals the [[harpsichord]]ist, [[pipe organ]]ist or [[lute]] player should play above each bass note.

[[File:Trifle In Pyjamas lead sheet.jpg|thumb|upright=1.5|The lead sheet for the song "Trifle in Pyjamas" shows only the melody and chord symbols. To play this song, a jazz band's [[rhythm section]] musicians would improvise chord voicings and a bassline using the chord symbols. The lead instruments, such as sax or trumpet, would improvise ornaments to make the melody more interesting, and then improvise a solo part.]]
