2.10.2 Arabic music

This section highlights issues that are relevant to notating Arabic music.


References for Arabic music

Arabic music so far has been mainly an oral tradition. When music is transcribed, it is usually in a sketch format, on which performers are expected to improvise significantly. Increasingly, Western notation, with a few variations, is adopted in order to communicate and preserve Arabic music.

Some elements of Western musical notation such as the transcription of chords or independent parts, are not required to typeset the more traditional Arabic pieces. There are however some different issues, such as the need to indicate medium intervals that are somewhere between a semi-tone and a tone, in addition to the minor and major intervals that are used in Western music. There is also the need to group and indicate a large number of different maqams (modes) that are part of Arabic music.

In general, Arabic music notation does not attempt to precisely indicate microtonal elements that are present in musical practice.

Several issues that are relevant to Arabic music are covered elsewhere:

Arabic note names

Traditional Arabic note names can be quite long and so may not always be suitable for the purpose of music writing.

The ‘hel-arabic.ly’ file allows English note names to be used. This is a rast scale using ‘hel-arabic.ly’;

\include "hel-arabic.ly"
\relative {
\key c \rast
  c' d edb f | g a bdb c | c bb a g | f d c
}

The ‘arabic.ly’ file allows Italian (or Solfege) note names to be used instead. This is a rast scale using ‘arabic.ly’;

\include "arabic.ly"
\relative {
  do' re misb fa | sol la sisb do | sisb la sol fa | misb re do
}

[image of music]

“Rast” is a heptatonic scale that uses quarter-tone intervals and is considered the most important and central scale of the “Arabic Maqamat”. For the full list of supported Arabic scales please refer to either the ‘hel-arabic.ly’ or ‘arabic.ly’ files that are both included with LilyPond.

The use of standard Western notation to notate non-Western music is discussed in Common notation for non-Western music. Also see Note names in other languages.

The symbol for semi-flat does not match the symbol which is used in Arabic notation. The \dwn symbol defined in ‘arabic.ly’ may be used preceding a flat symbol as a work around if it is important to use the specific Arabic semi-flat symbol. The appearance of the semi-flat symbol in the key signature cannot be altered by using this method.

\include "arabic.ly"
\relative {
  \set Staff.extraNatural = ##f
  dod' dob dosd \dwn dob dobsb dodsd do do
}

Arabic key signatures

In addition to the minor and major key signatures, Arabic key signatures are defined in either ‘hel-arabic.ly’ or ‘arabic.ly’ files and define many different maqam groups.

In general, a maqam uses the key signature of its group, or a neighbouring group, and varying accidentals are marked throughout the music. Arabic maqams only allow for limited modulations, due to the nature of Arabic musical instruments.

Here is an example of the key signature for a “maqam muhayer” piece of music:

\key re \bayati

Here re is the default pitch of the muhayer maqam, and bayati is the name of the base maqam in the group.

While the key signature indicates the group, it is common for the title to indicate the more specific maqam, so in this example, the name of “maqam muhayer” should also appear in the title.

Other maqams in the same bayati group, as shown in the table below (e.g., bayati, hussaini, saba, and ushaq) can be indicated in the same way. These are all variations of the base and most common maqam in the group, which is bayati. They usually differ from the base maqam in their upper tetrachords, or certain flow details that do not change their fundamental nature, as siblings.

The other maqam in the same group (nawa) is related to bayati by modulation and is shown in the table in parentheses for those that are modulations of their base maqam. Nawa, for example, can be indicated as follows:

\key sol \bayati

In Arabic music, the same term, for example bayati, that is used to indicate a maqam group, will also be a maqam that is usually the most important in the group so can also be thought of as a base maqam.

Here is one suggested grouping that maps the more common maqams to key signatures:

Non-traditional key signatures

The commonly used \key command sets the keyAlterations property in the Staff context. To create non-standard key signatures, set this property directly.

The format of this command is a list:

\set Staff.keyAlterations =
  #`(((octave . step) . alter) ((octave . step) . alter) ...)

where, for each element in the list octave specifies the octave (0 being the octave from middle c to the b above), step specifies the note within the octave (0 means c and 6 means b), and alter is ,SHARP ,FLAT ,DOUBLE-SHARP etc.

Alternatively, using the more concise format for each item in the list, (step . alter) specifies the same alteration holds in all octaves. For microtonal scales where a “sharp” is not 100 cents, alter refers to the proportion of a 200-cent whole tone.

\include "arabic.ly"
\relative do' {
  \set Staff.keyAlterations = #`((0 . ,SEMI-FLAT)
                                 (1 . ,SEMI-FLAT)
                                 (2 . ,FLAT)
                                 (5 . ,FLAT)
                                 (6 . ,SEMI-FLAT))
%\set Staff.extraNatural = ##f
  re reb \dwn reb resd
  dod dob dosd \dwn dob |
  dobsb dodsd do do |
}

Arabic time signatures

Some Arabic and Turkish music classical forms such as Semai use unusual time signatures such as 10/8. This may lead to an automatic grouping of notes that is quite different from existing typeset music, where notes may not be grouped on the beat, but in a manner that is difficult to match by adjusting automatic beaming. The alternative is to switch off automatic beaming and beam the notes manually. Even if a match to existing typeset music is not required, it may still be desirable to adjust the automatic beaming behaviour and/or use compound time signatures.

Arabic improvisation

For improvisations or taqasim which are temporarily free, the time signature can be omitted and \cadenzaOn can be used. Adjusting the accidental style might be required, since the absence of bar lines will cause the accidental to be marked only once. Here is an example of what could be the start of a hijaz improvisation:

\include "arabic.ly"

\relative sol' {
  \key re \kurd
  \accidentalStyle forget
  \cadenzaOn
  sol4 sol sol sol fad mib sol1 fad8 mib re4. r8 mib1 fad sol
}

Arabic music example

Here is a template that also uses the start of a Turkish Semai that is familiar in Arabic music education in order to illustrate some of the peculiarities of Arabic music notation, such as medium intervals and unusual modes that are discussed in this section.

\include "arabic.ly"
\score {
  \header {
    title = "Semai Muhayer"
    composer = "Jamil Bek"
  }
  \relative {
    \set Staff.extraNatural = ##f
    \set Staff.autoBeaming = ##f
    \key re \bayati
    \time 10/8

Further reading for Arabic music

There are some variations in the details of how maqams are grouped, despite agreement of grouping maqams related through common lower tetra chords or by modulation. There are also some inconsistencies, even within the same texts, on how key signatures for a particular maqam should be specified. However, it is common to use a key signature per ‘group’ of maqams instead of individual key signatures for each maqam separately.
