38 @cindex medium intervals
42 Arabic music so far has been mainly an oral tradition. When music
43 is transcribed, it is usually in a sketch format, on which
44 performers are expected to improvise significantly. Increasingly,
45 Western notation, with a few variations, is adopted in order to
46 communicate and preserve Arabic music.
48 Some elements of Western musical notation such as the
49 transcription of chords or independent parts, are not required to
50 typeset the more traditional Arabic pieces. There are however
51 some different issues, such as the need to indicate medium
52 intervals that are somewhere between a semi-tone and a tone, in
53 addition to the minor and major intervals that are used in Western
54 music. There is also the need to group and indicate a large
55 number of different maqams (modes) that are part of Arabic music.
57 In general, Arabic music notation does not attempt to precisely
58 indicate microtonal elements that are present in musical practice.

62 @unnumberedsubsubsec Arabic note names
64 @cindex Arabic note names
66 The more traditional Arabic note names can be quite long and are
67 not suitable for the purpose of music writing, so they are not
68 defined by the inclusion of @code{"arabic.ly"}. English note
69 names @code{a, b, c, d, e, f, g} are not very familiar in Arabic
70 music education. Italian or Solfege note names @code{do, re, mi,
71 fa, sol, la, si} are more familiar, and are used when
72 @code{"arabic.ly"} is included. Modifiers can also be used, as
73 discussed in @ref{Note names in other languages}.
75 For example, this is how the Arabic @notation{rast} scale can be
78 @lilypond[quote,verbatim]
81 do re misb fa sol la sisb do sisb la sol fa misb re do

93 @unnumberedsubsubsec Arabic key signatures
95 @cindex Arabic key signatures
97 In addition to the minor and major key signatures, the following
98 key signatures are defined in @code{"arabic.ly"}: bayati, rast,
99 sikah, iraq, and kurd. These key signatures define a small number
100 of maqam groups rather than the large number of maqams that are in
103 In general, a maqam uses the key signature of its group, or a
104 neighbouring group, and varying accidentals are marked throughout
107 For example to indicate the key signature of a maqam muhayer piece:
111 Here re is the default pitch of the muhayer maqam, and bayati is the
112 name of the base maqam in the group.
114 While the key signature indicates the group, it is
115 common for the title to indicate the more specific maqam, so in this
116 example, the name of maqam muhayer should appear in the title.
118 In Arabic music, the same term such as bayati that is used to indicate
119 a maqam group, is also a maqam which is usually the most important
120 in the group, and can also be thought of as a base maqam.
122 Here is one suggested grouping that maps the more common maqams to key
125 @multitable @columnfractions 0.1 0.1 0.1 0.6
126 @headitem maqam group
129 @tab Other maqmas in group (finalis)
137 @tab hussaini, muhayer, saba, ushaq, nawa (sol)
141 @tab shahnaz, shad arban (sol), hijazkar (do)

153 @tab busalik (re), farah faza (sol)
157 @tab nawa athar, hisar (re)
161 @tab mahur, yakah (sol)
169 You can also set the key signature using Staff.keySignature as discussed
170 in @ref{Key signature}. This offers more flexibility if you don't wish
171 to be limited to the key signatures that are defined in "arabic.ly", or if
172 you don't wish to use the above method of determining a key signature based
175 For example, you can set the key signature to do sharp, mi semi-flat, and
176 sol flat as follows :
178 @lilypond[quote,verbatim]
181 \set Staff.keySignature = #`( (0 . ,SHARP) (2 . ,SEMI-FLAT) (4 . ,FLAT) )

198 @unnumberedsubsubsec Arabic time signatures
200 @cindex Arabic time signatures
204 Some Arabic and Turkish music classical forms such as Semai use
205 unusual time signatures such as 10/8. This may lead to an
206 automatic grouping of notes that is quite different from existing
207 typeset music. You can override this by switching off automatic
208 beaming, and grouping the notes manually using @code{[ ]} to
209 surround grouped notes, as described in @ref{Manual beams}.
211 For improvisations or taqasim which are temporarily free, the time
212 signature can be omitted, and @code{\cadenzaOn} can be used.
213 You might need to adjust the accidental style, since the absence
214 of bar lines will cause the accidental to be marked only once:
217 #(set-accidental-style 'forget)

234 The music of the Arabs by Habib Hassan Touma [Amadeus Press, 1996],
235 contains a discussion of maqams and their method of groupings.
237 There are also various web sites that explain maqams and some
238 provide audio examples such as :
242 @uref{http://www.maqamworld.com/}
244 @uref{http://www.turath.org/}
247 There are some variations in the details of how maqams are grouped,
248 despite agreement on the criteria of grouping maqams that are
249 related through common lower tetra chords, or through modulation.
252 There is not a complete consistency, sometimes even in the same
253 text on how key signatures for particular maqams should be
254 specified. It is common, however, to use a key signature per
255 group, rather than a different key signature for each different
258 Oud methods by the following authors, contain examples of
259 mainly Turkish and Arabic compositions.
