Instrumental Ensembles ::

There are conventions that you should observe when laying out music in full score or as individual parts. Some have been mentioned earlier.

  • all staves have a clef sign followed by a key signature;
  • a time signature is only shown in the first bar of the work, except if and where it is changed;
  • if the time signature changes while the piece is in progress it does so only at the beginning of a bar;
  • each line of a score should be marked with the full or abbreviated name of the instrument playing it;
  • with single parts, the instrument need only be named at the top of the page;
  • braces group the lines of instruments like the piano (2 lines), organ (2 or 3 lines) or harp (2 lines);
  • in orchestral scores, braces group lines played by related instruments - e.g. flute(s) and piccolo;
  • bar lines are drawn through the instrumental lines belonging to those in the same section;
  • to conserve space, instruments of the same kind may be placed on the same line (e.g. when parts divide);
  • solo parts in concertos are normally placed immediately above the strings;
  • nowadays, choral lines also appear just above the strings;
  • two dark oblique lines may be placed between each line of the stave in full score;
  • parts for instruments, not required for extended periods, may be removed from the full score;
  • the parts will include sufficient multi-bar rests during extended periods of silence.

    We have illustrated, on the right hand side of this page, a full or open score for orchestra. The convention is that higher-pitched instruments or voices are usually placed higher on the page than lower-pitched parts. So, in orchestral scores, the groupings are by instrumental 'family': woodwinds on top of the page, and below them, in descending order, brass, percussion, harp and keyboards, soloists (instrumental or vocal), voices, and strings. Within each family, the arrangement is still from top to bottom by pitch, so that in the strings, for example, the violins are at the top and the double basses at the bottom.


    Solos & Parts ::

    Performers are generally happier to read from their own part and do not need to work from a full or open score. It is not unusual, in complex works, to include cues from other parts in the playing part, particular when there are extended periods of silence. These extracts will be printed using a smaller type face, placed on or above the playing line. Performers sometimes add further cues by hand (using a pencil) where these give confidence during a performance.

    Short, condensed or close scores are those with a smaller number of staves than in the full or open score. Each staff bears one or more lines, each line often identifiable because the note tails for a particular line are set up or down throughout the piece. An example of a condensed format is the reduction of a four-staff string quartet score to a two-staff 'treble and bass' piano-like form.

    If, as an exercise, you are asked to expand a close score back to its full or open form, remember to adopt the usual layout for the instruments required; transposing parts if the instruments require them and the correct clef (alto clef for viola, tenor clef for tenor voice, and so on) where appropriate.


    Keyboards ::

    We have illustrated the layout for a SATB (soprano, alto, tenor, bass) choir with a three line organ part (2 line keyboard part - 1 line pedal part). When vocal lines include 'spoken' rather than sung text, the untuned percussion symbol, the note-head is a small x.

    The examples below, the introductory bars of Irving Berlin's 'Blue Skies' and Bach's Fugue BWV 948 show how a composer can show inner parts within a keyboard score. 'Blue Skies' begins with an upper melody, and inner series of chords and a bass line. The inner chords have their tails flipped down to distinguish them from the melody above which has its tails pointing up.By bar 7 there are now four distinct lines. In addition, the second line is divided on the second beat and on the first quaver (eighth note) of the third beat. The composer wishes to make the four parts clear, hoping that the performer will do the same. In the Fugue, Bach makes clear the three independent fugal voices by writing three distinct lines.



  •  


    Percussion ::

    Tuned percussion parts use a five line stave. Some instruments, e.g. marimbas and harps, use a keyboard layout. Untuned percussion (the four lines at the top of the score below) may use the five line stave with standard note-heads (where each line or space refers to a different untuned percussion instrument in a set) or a single line with a special clef sign and note heads in the form of small x's, a symbol used to show a note of no predetermined pitch on one particular untuned percussion instrument.


    How to Write Parts for Transposing Instruments ::

    In many modern works, transposing instruments, that is those where the player reads one note but produces a different note, may be written, in the score, as they are heard rather than as they are read. The individual parts, however, would still be set out with the standard transposition. By notating the whole score at concert pitch, give or take octave transpositions, it is much easier to 'see' the harmonic and melodic detail. Pre-20th century scores are written with the transposing parts as they are read.

    Transposed parts are commonly used for brass and some woodwind instruments.

    These are some examples of transposing instruments:

    Bb trumpet
    French horn (F)
    Alto saxophone (Eb)
    Tenor saxophone (Bb)
    Cor anglais (F)
    Bb clarinet
    A clarinet

    Before writing for a transposing instrument you need to know its key, any octave shifts in the transposition and the clef the player expects to read.

    One example shows their advantage. Clarinets come in different sizes but all have the same fingering system. If a player reads a part that prompts for the fingering rather than for the note, changing between instruments is much easier. So what happens is this. All clarinet parts read as though the bottom note is C. This is the note both a B flat and an A clarinet player will read. However, the former produces a B flat while the latter produces an A. If the part is transposed relative to instruments that play what they read, the correct note is heard. The same convention is used by brass players so that, as one moves from one member of the brass instrument family to another, one is using only one note read - fingering convention. The way the part is transposed takes care of the fingering - note heard relationship.

    So, what is the correct recipe? Let us write a transposed part for Bb trumpet, that is, a part the trumpet will play from.

    The Bb trumpet part is transposed a whole tone above concert/sounding pitch. So if the composer/arranger wants the trumpet to sound a B flat he or she must write a C in the trumpet player's part. Let us begin with a concert/sounding pitch part in the full score and produce a part for the trumpeter to play from, i.e. a transposed part.

    First remember to transpose the key signature up a tone above concert/sounding pitch. Note: the key signature is that one tone higher than the key signature shown in on the concert/sounding pitch line in the score.

    Eb concert transposes up one tone to F (i.e. Eb + one semitone = E; E + one semitone = F)
    C concert transposes up one tone to D (i.e. C + one semitone = C#; C# + one semitone = D)
    D concert transposes up one tones to E (i.e. D + one semitone = D#; D# + one semitone = E)
    and so on ....

    One can write out a table to help keep track of the correct adjustment.

    Concert part - sounds key/note Eb F G Ab Bb C D Eb
    Transposing part - reads key/note F G A Bb C D E F

    We can examine another example, the baritone saxophone which is scored in the full score in bass clef but whose extracted transposing part is written up a diatonic 13th (diatonic 6th and an octave) to the treble clef.

    First one raises the part in the bass clef by one octave, then by a further 6th and final converts the final line into treble clef. Note: don't forget to adjust the key signature too. As with the trumpet part above, it helps to set out a table showing the concert/sounding key and the note up to which it must be transposed on the player's part.

    Concert part - sounds key/note C D E F G A B C
    Transposing part - reads key/note A B C# D E F# G# A

    Let us summarise what we have said above by showing below an example of how a chord might be written in a score and what notes the listener would actually hear in each case. The only non-transposing instruments are the flute and the oboe.

    As written in the score

    As heard by the listener

    One of our readers asked an interesting question. "I have a B flat clarinet part that I would like to play on a clarinet in A. How do I transpose the part so that the notes my instrument sounds reproduce the notes the B flat clarinet sounded on the original transposed part?".

    Let us review how the parts for B flat and A clarinets are written. Earlier we wrote: "All clarinet parts read as though the bottom note is C. This is the note both a B flat and an A clarinet player will read. However, the former produces a B flat while the latter produces an A. If the part is transposed relative to instruments that play what they read, the correct note is heard."

    The key to solving our reader's question lies in the way the transposing parts for these two instruments are written. To play the note C in C major, a B flat clarinet part notates a B flat in a part bearing a key signature with 2 flats, the key signature for B flat major while an A clarinet part notates an A in a part bearing a key signature with 3 sharps, the key signature for A major. So we know that a B flat in a B flat clarinet part has to be rewritten as an A, a semitone (half step) lower, in an A clarinet part and the key signature has to be changed from two flats to three sharps, equivalent to adding five sharps to the original key signature (two sharps cancel the two flats, plus a further three sharps to establish the new key). This gives us our 'recipe'.

    Were we moving the other way (from a part for clarinet in A to a part for clarinet in B flat), the shifts would be the reverse, the part would be written one semitone higher and the key signature would be shifted by the equivalent of 5 flats.

    An additional question is what should one do when creating a transposed score (or extracting transposed parts) of an atonal piece which is notated without key signatures. Should transposing instruments have key signatures (which put them into concert C)? The best convention (which is set out on the Music Notation Questions Answered web page) suggests that such parts, whether in a score or individual, should be notated transposed but without a key signature. The presence of a key signature would at best be misleading since the piece is not actually in any particular key.

    Many older pieces for horn were written for a horn not keyed in F as is standard today. As a result a requirement for modern orchestra hornists is to be able to read music directly in these keys. This is most commonly done by transposing the music on the fly into F. A reliable way to transpose is to liken the written notes (which rarely deviate from written C,D,E, and G) to their counterparts in the scale the F horn will be playing in.

    commonly seen French horn transpositions include:
    Bb alto (in German, indicated as B)up a perfect fourth
    A altoup a major third
    Gup a major second
    Edown a minor second
    Ebdown a major second
    Ddown a minor third
    Cdown a perfect fourth
    Bb basso (in German indicated as B)down a perfect fifth
    Some less common transpositions include:
    Ab altoup a minor third
    Gbup a minor second
    Dbdown a major third (used in some works by Berlioz, Verdi and Strauss (Der Rosenkavalier))
    B (in German indicated as H)down a tritone (used by Brahms)
    A bassodown a minor sixth (used in some works by Verdi)
    Ab bassodown a major sixth (used in some works by Verdi)
    G bassoup a minor seventh (used in some works by Verdi)
