One of the most notable composers of "new synthesis" Ottoman classical music is KasÄmpaÅŸalÄ Osman Effendi, whose focus, along with his students, was on reviving the tradition of complex rhythmic cycles, which he had correctly identified as lost, unlike many court musicologists of his time.[10] These new rhythmic cycles were later used by his student HafÄz Post to fit the more folkloric, popular poetry form murabba, bridging the gap between older Persian classical works and newer Anatolian ones, created after the decline of Persian music in the 16th century.[10] Meanwhile, other students of Osman Effendi, such as Mustafa Itri, sought out the conventions of Byzantine music, incorporating the concepts of the Orthodox tradition into his works as well as his treatises. This significantly bolstered the exchange between Byzantine and Ottoman music, and the resulting era featured a number of Greek composers, most notably Peter Peloponnesios, Hanende Zacharia and Tanburi Angeli.[10][13] Increasingly, modal structures between the two traditions began to converge as well, as manuscripts often recorded both echoi and makams of composed pieces. A piece during this time might have been recorded as "SegÃh makam, usÃl muhammes, echos IV legetos", noting similarities and equivalences between the two systems.[16]
While Ottoman music does have characteristics in common with Western classical music, to which it is often compared, Ottoman music theory is largely dependent on two systems separate from that of common practice Western tradition, a system of modal melodic material called makam, and a system of rhythmic cycles called usÃl.[20] The theoretical basis of this "melodic material" is a tuning system that divides the octave into 53 tones or perdes, and prescribes heterophonic "pathways" of melodic development, called seyir, to create pieces.[23] If said melodic material is used in its "purest" form, the resulting composition is called a taksim, or a locally-rhythmic improvisational piece. Composed pieces, however, also utilize usÃl, a complex system of meters and accents, which structure the piece.[20]
PeÅŸrevs are performed after the introductory taksim in a classical fasÄl. PeÅŸrevs are rhythmically complex, featuring protracted usuls that do not translate well into Western staff notation.[20] They are typically made up of four hÃnes and one mÃlazime, which repeats after every hÃne,[24] and its melodic structure relies on alternating between neighboring makams in these hÃnes.[11] PeÅŸrevs, in addition to serving as preludes for long-form performances, also have a very comprehensive history in their usage as military marches, and therefore, has had a considerable influence on Western classical music.[11] Melodically complex peÅŸrevs with numerous modal modulations are called Fihrist peÅŸrevs, or KÃll-i KÃlliyat.[11]
3. Turkish Tetrachords: Following the example of the ancient Greeks, Turkish makams are the combination of two four-note groupings called tetrachords. Through the use of accidentals, a series of tetrachords, each with a different characteristic (and name) can be created. Unlike the West, the dominant (D) will sometimes be located within the tetrachord itself. The following examples are the basic tetrachords (and pentachords) of Turkish classical music:
4. Turkish Makams: By joining tetrachords and pentachords, complete scales and modes are created. There are thousands of musical examples of works written using hundreds of different makams in the literature of Turkish classical music. Makam names vary according to pitches used as well as general direction of the melodic flow. Thus makams are really rules of composition and not just scales. Here are just a few examples:
Note: Turkish folk music, while not as highly refined or theoretical as Turkish classical music, has many examples of songs written in different makams including Hicaz, Huseyni and Ussak.
