Since the early 20th century, various theories have been advanced in order to mathematically explain and notate modes of Traditional Turkish music known as maqams. In this article, maqam scales according to various theoretical models based on different tunings are compared with pitch measurements obtained from select recordings of master Turkish performers in order to study their level of match with analysed data. Chosen recordings are subjected to a fully computerized sequence of signal processing algorithms for the automatic determination of the set of relative pitches for each maqam scale: f0 estimation, histogram computation, tonic detection+histogram alignment, and peak picking. For nine well-recognized maqams, automatically derived relative pitches are compared with scale tones defined by theoretical models using quantitative distance measures. We analyse and interpret histogram peaks based on these measures to find the theoretical models most conforming with all the recordings, and hence, with the quotidian performance trends influenced by them.

A tool for comparison of piano performances
Bora, U; Tufan, S; Bilgen, Semih (Informa UK Limited, 2000-01-01)
In this paper a tool designed for analyzing music performance is introduced. The tool interprets a performance of a piano piece and lists the "errors" it finds by comparing the performance to a pre-recorded expert performance of that piece, utilizing MIDI files. It is primarily intended to be used in piano education. Examples of applications as well as the architecture and design of the tool are given.
Effects of musical training and culture on meter perception
Yates, Charles M.; Justus, Timothy; ATALAY, NART BEDİN; Mert, Nazike; Trehub, Sandra E. (2017-03-01)
Western music is characterized primarily by simple meters, but a number of other musical cultures, including Turkish, have both simple and complex meters. In Experiment 1, Turkish and American adults with and without musical training were asked to detect metrical changes in Turkish music with simple and complex meter. Musicians performed significantly better than nonmusicians, and performance was significantly better on simple meter than on complex meter, but Turkish listeners performed no differently than ...
A MODEL FOR TONAL CONTEXT TIME COURSE CALCULATION FROM ACOUSTICAL INPUT
IZMIRLI, O; BILGEN, S (Informa UK Limited, 1996-09-01)
This paper presents a two‐stage model that calculates tonal context as a continuous function in time. The model is capable of processing acoustical polyphonic inputs. The first stage is a simple note recogniser that produces pitch‐class note output corresponding to the acoustical input. A bank of leaky integrators constitute the second stage. The integration rates and saturation limits of these integrators vary with each musical event according to the relations among input notes and the candidates of tonal ...
Making art in the early Turkish Republic : The Academy of Fine Arts in İstanbul and The Art-Craft Department in Ankara
Becker, Martina; Altan, Tomris Elvan; Department of History of Architecture (2013)
This dissertation studies creative practices in the early Turkish Republic alongside their conceptualisation as art, as a means of transcending the epistemic confines of traditional art historiography while addressing phenomena that themselves had little agency in establishing those confines. The study centres on the Academy of Fine Arts in Istanbul and the Art-Craft Department in Ankara. The two schools were not the exclusive sites of creative practices in Turkey, yet, as the only public institutions of pr...
The mathematical analysis of the structure of some songs
Gunduz, G; Gündüz, Ufuk (2005-11-15)
The mathematical structures of six songs were studied by treating them as complex systems. The studies were based on (i) scattering diagram, (ii) spiral structure, (iii) graph theory and animal diagrams, and (iv) entropy and organization. In (i), the fractal dimension and the radius of gyration was determined for each melody. In (ii), it was shown that the total number of notes used in a song display a spiral, which can be expressed by a mathematical equation. In (iii), the animal diagram was obtained by us...
