Sheet Music - Types

Types

Modern sheet music may come in different formats. If a piece is composed for just one instrument or voice (such as a piece for a solo instrument or for a cappella solo voice), the whole work may be written or printed as one piece of sheet music. If an instrumental piece is intended to be performed by more than one person, each performer will usually have a separate piece of sheet music, called a part, to play from. This is especially the case in the publication of works requiring more than four or so performers, though invariably a full score is published as well. The sung parts in a vocal work are not usually issued separately today, although this was historically the case, especially before music printing made sheet music widely available.

Sheet music can be issued as individual pieces or works (for example, a popular song or a Beethoven sonata), in collections (for example works by one or several composers), as pieces performed by a given artist, etc.

When the separate instrumental and vocal parts of a musical work are printed together, the resulting sheet music is called a score. Conventionally, a score consists of musical notation with each instrumental or vocal part in vertical alignment (meaning that concurrent events in the notation for each part are orthographically arranged). The term score has also been used to refer to sheet music written for only one performer. The distinction between score and part applies when there is more than one part needed for performance.

Scores come in various formats, as follows:

• A full score is a large book showing the music of all instruments and voices in a composition lined up in a fixed order. It is large enough for a conductor to be able to read it while directing rehearsals and performances.
• A miniature score is like a full score but much reduced in size. It is too small for use in performance, but handy for studying a piece of music, whether it be for a large ensemble or a solo performer. A miniature score may contain some introductory remarks.
• A study score is sometimes the same size as, and often indistinguishable from, a miniature score, except in name. Some study scores are octavo size and are thus somewhere between full and miniature score sizes. A study score, especially when part of an anthology for academic study, may include extra comments about the music and markings for learning purposes.
• A piano score (or piano reduction) is a more or less literal transcription for piano of a piece intended for many performing parts, especially orchestral works; this can include purely instrumental sections within large vocal works (see vocal score immediately below). Such arrangements are made for either piano solo (two hands) or piano duet (one or two pianos, four hands). Extra small staves are sometimes added at certain points in piano scores for two hands in order to make the presentation more complete, though it is usually impractical or impossible to include them while playing. As with vocal score (immediately below), it takes considerable skill to reduce an orchestral score to such smaller forms because the reduction needs to be not only playable on the keyboard but also thorough enough in its presentation of the intended harmonies, textures, figurations, etc. Sometimes markings are included to show which instruments are playing at given points. While piano scores are usually not meant for performance outside of study and pleasure (Liszt's concert transcriptions of Beethoven's symphonies being one group of notable exceptions), ballets get the most practical benefit from piano scores because with one or two pianists they allow unlimited rehearsal before an orchestra is absolutely needed. They can be used also to train beginning conductors. Piano scores of operas do not include separate staves for the vocal parts, but they may add the sung text and stage directions above the music.

• A vocal score (or, more properly, piano-vocal score) is a reduction of the full score of a vocal work (e.g., opera, musical, oratorio, cantata, etc.) to show the vocal parts (solo and choral) on their staves and the orchestral parts in a piano reduction (usually for two hands) underneath the vocal parts; the purely orchestral sections of the score are also reduced for piano. If a portion of the work is a cappella, a piano reduction of the vocal parts is often added to aid in rehearsal (this often is the case with a cappella religious sheet music). While not meant for performance, vocal scores serve as a convenient way for vocal soloists and choristers to learn the music and rehearse separately from the instrumental ensemble. The vocal score of a musical typically does not include the spoken dialogue, except for cues.
  • The related but less common choral score contains the choral parts with no accompaniment.
  • The comparable organ score exists as well, usually in association with church music for voices and orchestra, such as arrangements (by later hands) of Handel's Messiah. It is like the piano-vocal score in that it includes staves for the vocal parts and reduces the orchestral parts to be performed by one person. Unlike the vocal score, the organ score is sometimes intended by the arranger to substitute for the orchestra in performance if necessary.
  • A collection of songs from a given musical is usually printed under the label vocal selections. This is different from the vocal score from the same show in that it does not present the complete music, and the piano accompaniment usually is simplified and includes the melody line.
• 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.
• A lead sheet specifies only the melody, lyrics and harmony, using one staff with chord symbols placed above and lyrics below. It is commonly used in popular music to capture the essential elements of song without specifying how the song should be arranged or performed.
• A chord chart or "chart" contains little or no melodic information at all but provides detailed harmonic and rhythmic information. This is the most common kind of written music used by professional session musicians playing jazz or other forms of popular music and is intended primarily for the rhythm section (usually containing piano, guitar, bass and drums).
• A tablature is a special type of musical score — most typically for a solo instrument — which shows where' to play the pitches on the given instrument rather than which pitches to produce, with rhythm indicated as well. This type of notation, which dates from the late Middle Ages, has been used for keyboard (e.g., organ) and for fretted string instruments (lute, guitar).
