+Turkish classical music developed in the Ottoman Empire in a
+period roughly contemporaneous with classical music in Europe,
+and has continued on into the 20th and 21st centuries as a
+vibrant and distinct tradition with its own compositional
+forms, theory and performance styles.  Among its striking
+features is the use of microtonal intervals based on @q{commas}
+of 1/9 of a tone, from which are constructed the melodic
+forms known as @notation{makam} (plural @notation{makamlar}).
+
+Some issues relevant to Turkish classical music are covered

+
+Pitches in Turkish classical music traditionally have unique
+names, and the basis of pitch on 1/9-tone divisions means
+makamlar employ a completely different set of intervals from
+Western scales and modes: @notation{koma} (1/9 of a tone),
+@notation{eksik bakiye} (3/9), @notation{bakiye} (4/9),
+@notation{kücük mücenneb} (5/9), @notation{büyük mücenneb}
+(8/9), @notation{tanîni} (a whole tone) and
+@notation{artık ikili} (12/9 or 13/9 of a tone).
+
+From a modern notational point of view it is convenient to
+use the standard Western staff notes (c, d, e, ...) with
+special accidentals that raise or lower notes by intervals
+of 1/9, 4/9, 5/9 and 8/9 of a tone.  These accidentals are
+defined in the file @file{makam.ly} (to locate this file on
+your system, see @rlearning{Other sources of information}).
+A more detailed description is provided in
+@ref{Non-Western note names and accidentals}.
