Tarsos - a Platform to Explore Pitch Scales in Non-Western and Western Music
نویسندگان
چکیده
This paper presents Tarsos 1 , a modular software platform to extract and analyze pitch and scale organization in music, especially geared towards the analysis of non-Western music. Tarsos aims to be a user-friendly, graphical tool to explore tone scales and pitch organization in music of the world. With Tarsos pitch annotations are extracted from an audio signal that are then processed to form musicologically meaningful representations. These representations cover more than the typical Western 12 pitch classes, since a fine-grained resolution of 1200 cents is used. Both scales with and without octave equivalence can be displayed graphically. The Tarsos API 2 creates opportunities to analyse large sets of ethnic music automatically. The graphical user interface can be used for detailed, manually adjusted analysis of specific songs. Several output modalities make Tarsos an interesting tool for musicological analysis, educational purposes and even for artistic productions.

Sound to Scale to sound: a setup for Microtonal Exploration and Composition
This paper elaborates on a setup for microtonal exploration, experimentation and composition. Where the initial design of the software Tarsos aimed for the scale analysis of ethnic music recordings, it turned out to deliver a flexible platform for pitch exploration of any kind of music. Scales from ethnic music, but also theoretically designed scales and scales from musical practice, can be ana...
متن کاملHomayoun as a Persian Music Scale on Non-Musician’s Brain: an fMRI Study
Introduction: The aim of this study was to get to a neurological evaluation of one of the Persian music scales, Homayoun, on brain activation of non-musician subjects. We selected this scale because Homayoun is one of the main scales in Persian classical music which is similar to minor mode in western scales. Methods: This study was performed on 19 right handed subjects, Aging 22-31. Here some ...
متن کاملPitch-interval discrimination and musical expertise: is the semitone a perceptual boundary?
The ability to discriminate pitch changes (or intervals) is foundational for speech and music. In an auditory psychophysical experiment, musicians and non-musicians were tested with fixed- and roving-pitch discrimination tasks to investigate the effects of musical expertise on interval discrimination. The tasks were administered parametrically to assess performance across varying pitch distance...
متن کاملBeethoven's last piano sonata and those who follow crocodiles: cross-domain mappings of auditory pitch in a musical context.
Though auditory pitch is customarily mapped in Western cultures onto spatial verticality (high-low), both anthropological reports and cognitive studies suggest that pitch may be mapped onto a wide variety of other domains. We collected a total number of 35 pitch mappings and investigated in four experiments how these mappings are used and structured. In particular, we inquired (1) how Western s...

In this paper we have extracted the notes of Iranian scale from the traditional music played by the great musician Shahnazi on the TAR. Then, by analyzing the spectrum of the notes and by using our special averaging we have found the pitch attributed to the components’ frequency and found the interval between the notes. The results are in comple agreement with Pythagorean scale. Pitch is a su...
