A New Representation System in Tonal Harmony for Analysis and Creation
نویسنده
چکیده
A new system of music harmony representation proposes an alternative space for establishment of the connection patterns. The system is based on the functional harmonic logic and uses graph theory for construction of the frame units: a basic proto-frame structure unfolds to the system of exoframes presented as graphs. Grouping of the frame instances (representing harmonic progressions) based on their resemblance creates a higher structural level of the harmony logic. The received graph patterns may be further expressed graphically, with a unified system of shapes (schemas), or logically, in alphabetic representation. The schema representation allows us to represent the process of harmonic development of the whole composition in one range of graphical shapes placed on the time line. The structural harmony method with the two-level representation opens huge possibilities for comparison of a large amount of the frame instances represented in a very concise manner.

The MusES system: an environment for experimenting with knowledge representation techniques in tonal harmony
We report here on current works on the MusES environment, designed for experimenting with various objectoriented knowledge representation techniques in the field of tonal harmony. The first layer of MusES is a repository of consensus knowledge about tonal harmony, including an explicit representation of enharmonic spelling, as well as representation of intervals, scales and chords that support ...
متن کاملHarmony in the Polyphonic Songs of Epirus: Representation, Statistical Analysis and Generation
This paper examines a previously unstudied musical corpus derived from the polyphonic singing tradition of Epirus employing statistical methods. This analysis will mainly focus on unique harmonic aspects of these songs, which feature, for instance, unresolved dissonances (major second and minor seventh intervals) at structurally stable positions of the pieces (e.g. cadences). Traditional triadi...
متن کاملEvaluating the General Chord Type Representation in Tonal Music and Organising GCT Chord Labels in Functional Chord Categories
The General Chord Type (GCT) representation is appropriate for encoding tone simultaneities in any harmonic context (such as tonal, modal, jazz, octatonic, atonal). The GCT allows the re-arrangement of the notes of a harmonic sonority such that abstract idiom-specific types of chords may be derived. This encoding is inspired by the standard roman numeral chord type labelling and is, therefore, ...
متن کاملAutomatic Functional Harmonic Analysis
Music scholars have been studying tonal harmony intensively for centuries, yielding numerous theories and models. Unfortunately, a large number of these theories are formulated in a rather informal fashion and lack mathematical precision. In this article we present HarmTrace, a functional model of Western tonal harmony that builds on well-known theories of tonal harmony. In contrast to other ap...

Iris recognition is one of the most reliable methods for identification. In general, itconsists of image acquisition, iris segmentation, feature extraction and matching. Among them, iris segmentation has an important role on the performance of any iris recognition system. Eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. In thi...
