Reverb Digital audio effect based on convolution with impulse response of acoustic room
Tichý, Vladimír ; Rajmic, Pavel (referee) ; Mačák, Jaromír (advisor)
This work deals with a computer simulation of an acoustic room using its impulse response. Two different approaches to the simulation are described with their pros and cons and then the work is focused on the physical approach, which uses room’s impulse response during the simulation. Several methods for the extraction of the impulse response of the acoustic room are mentioned with their conditions of use. The detailed description of various algorithms for a real time convolution computing is followed by the cost analysis of frequency domain block convolution algorithms. Several algorithms are chosen, implemented and tested in Matlab environment. Then the most effective of them is chosen to be implemented in VST technology as the plug in module for real time room simulation.

Musical time - its deviation from the astronomical time
Oplištilová, Iva ; TICHÝ, Vladimír (advisor) ; Šťastný, Jaroslav (referee)
My dissertation is based differentiating individually experienced, musical time, and shared, astronomical time. I combine the knowledge gained in cognitive science experiments with music-theoretical approach following the path from sound received to the hierarchized representation of the temporal component of music. My focus are those possible mechanisms that allow deviation of musical time from the astronomical one and the factors influencing them. As concerns music theory, I chose the analytical tools provided by the General Theory of Segmentation and the Recontextualization Theory by D. A. Hanninen. The inner sharing of pulse by the listener or performer with the pulse of sounding music I consider to be the decisive moment for/in the deviation of musical time. I link the pulse boundary with prospective and retrospective strategies of the perceiving person. My considerations unfold on an axis between two poles of pulse and gesture, i.e. between full kinaesthetic synchronization with the outer, shared time and the maximum deviation dependent on the individual manner the gesture is internally represented. I convey the hypothesis that the deviation of musical time is possible only with retrospective strategies of processing of musical events.
My theoretical considerations and suitability of the chosen analytical tools/means are verified in the second part, in analyses of compositions by G. Grisey, O. Messiaen, P. Kotík, P. Graham and A. Breier. Enclosed are also some theoretical reflections of these composers concertning their work with time.

Theoretical basic of the organ interpretation
Dvořáková, Jiřina ; HAVLÍK, Jaromír (advisor) ; TICHÝ, Vladimír (referee)
This work tries to explaine the history of organ interpretation and it´s evolution in Czechoslovakia between 1945 and 1989. Determining the cause of the organ interpretation, the work presents a new system ? the analysis of the musical interpretation in general. This analysis tries to describe musical interpretation as a logical and paradigmatical system based on elements of interpretation during the performing event. These elements are characterized as two hierarchical levels expalined by semantic and structural categories of the composition.

Factors affecting the Developement of harmonic Field
Zvěřina, Petr ; TICHÝ, Vladimír (advisor) ; KVĚCH, Otomar (referee)
The main focus of the thesis is the determination and discussion of factors affecting the developement of harmonic field. The main factors are the importance and significance of individual tones and chords, their mutual influencing and organization, and their relationship to the time component of the composition. I attempt to find out how can these factors help us to comprehend the harmony of composition. I define the general tectonic scheme, that is related to the theory of harmonic field and I consider it to be its extension. The second part of the work is focusing on traditionally used terms and I´m trying to discuss how the determined factors manifest in them. I pay attention to the terms of the common-practice harmony and also to the modern harmony. I?m exploring the ideas of Miroslav Filip (The Regularities of Developement of Common-Practice Harmony), Karel Janeček (The Foundations of Modern Harmony, Tectonics) and Vladimír Tichý (Harmonic Field). The third part of the work contains three analysis of various pieces of diverse composers (Mozart, Webern, Feldman). I´ve tried to analyse these compositions on the basis of foregoing premises so I could prove the applicableness of my thoughts.

On the Question of transcendent Time in Music
Míšek, Jakub ; TICHÝ, Vladimír (advisor) ; MATOUŠEK, Vlastislav (referee)
The concern of this thesis is the relationship between music and time, more precisely a specific kind of temporality, which is known as transcendent, sacred, sacral or "the third" time. This text is meant to be an introduction into the subject matter. At first the relationship between musical and non-musical time is discussed. Then the phenomenon of transcendent time is put into the relationship with theories of musical time presented by other, both Czech and foreign, authors. The last part of this paper contains an exemplary listing of composer strategies which can help in inducing an experience of transcendent time. These strategies are demonstrated on songs and compositions originating in different genres and cultures.

Least squares method using genetic algorithm
Holec, Matúš ; Tichý, Vladimír (advisor) ; Šalamon, Tomáš (referee)
This thesis describes the design and implementation of genetic algorithm for approximation of non-linear mathematical functions using the least squares method. One objective of this work is to theoretically describe the basics of genetic algorithms. The second objective is to create a program that would be potentially used to approximate empirically measured data by the scientific institutions. Besides the theoretical description of the given subject, the text part of the work mainly deals with the design of the genetic algorithm and the whole application solving the given problem. Specific part of the assignment is that the developed application has to support approximation of points by various mathematical non-linear functions in several different intervals, and then it has to insure, that resulting functions are continuous throughout all the intervals. Described functionality is not offered by any available software.

Analysis of polyphony of indigenous people of Solomon Islands
Míšek, Jakub ; Tichý, Vladimír (advisor) ; Matoušek, Vlastislav (referee)
MÍŠEK, Jakub: Analysis of Polyphony of Indigenous People of Solomon
Islands. [Bachelor?s thesis]. Academy of Performing Arts in Prague. Music
Faculty; Department of Music Theory and Music History. Thesis advisor :
prof. Vladimír Tichý, CSc. Degree: Bachelor of Music Theory. Prague :
HAMU, 2011. Pp. 70.
The thesis provides an analytic view of the music of indigenous people of
Solomon Islands which is distinguished by its frequent use of polyphony.
A Czech reader going through the foreign, especially English-written
literature, discovers a frequent use of the word polyphony. The thesis
attempts to decide whether all these cases are entitled to be labelled with
the Czech equivalent of the word polyphony, polyfonie. After a brief
summary of the historical development in the region and depicting the
main features of local musical cultures, the thesis presents nine analyses
of examples of vocal songs coming from the islands of Guadalcanal,
Malaita and Savo, which are focused on issues of melody, rhythm and
structure. The last part deals with questions of homophony, heterophony
and polyphony and explores their relationships and overlaps. Using my
original method of analysis based on perceptual approach, the thesis
proves that the term polyfonie can be used for non-European music.
Keywords: Solomon Islands, ethnomusicology, homophony, heterophony,
polyphony
