Musical Signal Synthesis on Android
Mikulík, Jan ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
The main task of this thesis is to design and implement new synthesizer on mobile platform under Android. The synthesizer generates three types of signals - sine, sawtooth and square. Two types of filters can be applied, low pass and high pass, and their cut-off frequency can be controlled. For the sound interpretation, an AudioTrack API was used. The synthesizer is controlled by zones, where one zone equals one tone. Zones can be selected by the user. For this synthesizer, a simple user interface was created.

Electronic Drum Control Module
Doležal, Karel ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This paper deals with development and construction of an electronic drum module. The purpose of the device is to capture signals from an electronic drumkit and to produce sound accordingly. Firstly, a protoype with no sound output is constructed to demonstrate an ability to capture input signals. Based on its function, parameters for a final device are determined. Then, electronic component selection and design of printed circuit boards is described with an aim to maximalize polyphony and minimize latency of the sound generator. After that, firmware with software mixing algorithm is designed. Lastly, testing and measurement of real device parameters is performed.

Electric Violin
Vaněk, Miroslav ; Fajt, Pavel (referee) ; Zdařil, Zdeněk (advisor)
The subject of my diploma thesis is design and realization of a five strings electric violin. This work builds on my theoretical diploma work named Development of the violin up to the present. The body of the violin is made of solid wood (beech) as same as the chin rest, fingerboard and bridge (walnut). The body is white coloured and varnished. In the left rib is placed el. sound output – 6.3 mm jack. The violin is equipped with piezo pickup Shadow SH SV1. Removable part of the violin is the shoulder rest. It has two support points.

Design of Digital Piano
Sikora, Halina ; Sládek, Josef (advisor)
This master’s thesis deals with the design of a digital piano. This increasingly popular musical instrument offers possibilities not available in an acoustic piano (outputting sound into headphones, utilizing sample libraries, recording, use of sheet music in digital form and more). From technical standpoint, it attempts to closely mimic the qualities of traditional instruments, both in its tactile feedback and sound quality. The aim of this work was to design a solution which would starkly differentiate from the very conservative classical design without being overly extravagant. The main focus is therefore on aspects of visual appearance, with emphasis on ergonomics, and an outline of the technical solution.

Electric Violin
Domorád, Petr ; Bělohlávek, Jan (referee) ; Zdařil, Zdeněk (advisor)
The bachelor thesis deals with the design of the new design of electric violins. The aim of the work is to break away from the stereotypes and traditional forms of baroque acoustic violins, which are in the design of electric violins often occur . Electric Violin therefore become a kind of substitute for classical violin , this may include a specific instrument , which allows to experiment with violin tones considerably richer . The new design of the shape electric violin should be ergonomically correct for easy violin , but interesting , new and unusual . When designing and manufacturing must be some part of classical violin left ( eg the shape of the neck or fingerboard ) . These parts may slightly vary because each said portion has a specific role to play violin . Proposal for violin based on the basic ergonomic features violin. From classical violin are left only parts which are to preserve functionality may change shape. Three into the protruding part of the body support a comfortable grip of instrument and mechanics, which is located at its ends , allows adjustability holding of instrument by violinist characters . Violin comply with rotational symmetry , which is an advantage , since the instrument can be used right-handed and left-handed. The proposal addresses the fact that the various components do not interfere with the violin ( eg potentiometers for volume and tone controls or instrument input cable for connecting the instrument to the apparatus ) . As these details when control may not see a violinist , but is usually controlled through hearing , are placed in the bottom of the hull of the violin , where playing the violin will not mind a useless way. The material used for the prototype of a violin is wood (possible combinations of various different types of wood for a better visual effect and to promote the curves of the body tools), which, after milling the surface treatment and paint several layers of lacquer . Components for attaching strings and adjustable drives are made of metal. Electronics, which is mounted inside the cavity of the tool body is bought, the additional component.

Materials for Production of Chords for Musical Instruments
Krhut, Štěpán ; Němec, Karel (referee) ; Molliková, Eva (advisor)
My bachelor’s work is about materials used for making the musical strings and its protection against its wear off. The introduction deals with evolution and history of the musical strings and the next chapters explain physical basics of the vibrations and how to make the musical string. There are also highlighted and many times mentioned guitar strings in my work due to the string manufacturers are made to develop and implement various high level demands into the strings because of the many various guitar playing techniques.

Music education in visually impaired students in primary education, especially at elementary schools of art
MINAŘÍKOVÁ, Mirka
The Bachelor thesis deals with the issue of music education in visually-impaired students at the first stage of elementary school. The thesis focuses on elementary art schools. The goal of the thesis has been to use a theoretical foundation in order to describe and map out the music education of visually impaired elementary art school students. The theoretical part contains three main chapters, the first of which explains the term visual impairment and lists its various categories while mentioning options for using the auditory, olfactory, and gustatory senses as compensatory senses by the visually impaired. The second chapter summarily describes the options and methods of educating visually impaired students. The third, last chapter focuses on the field of music education. The largest part deals with the music education of visually impaired students in elementary art schools. A qualitative procedure was used in the practical part of the thesis to attain its research goals. Questioning and semi-structured interviews were used for data collection. A total of 8 respondents, from the ranks of Jižní Čechy Region elementary art school presidents, vice-presidents, and teachers, have been interviewed, with all of whom having experience with teaching visually impaired students. The output of processing the results of the practical part leads to several findings. Teachers who teach visually impaired student and lack the specialized education for teaching such students have only one option for leading their students methodically-namely to stay in touch and cooperate with the teachers of the Jan Deyl Conservatory in Prague. Adopting the Braille writing system as well as theoretical basics of music education, and thereby the actual execution of music education, are both very important in allowing a visually impaired student to play a musical instrument and in opening up to them the possibility of further education in an artistic field. What matters in playing a musical instrument is correct initiation of lessons, cooperation between the teacher and the child and his/her parents, and educational rigor on part of the teacher , who must take into account the personal capabilities, options, and needs of a student. There are several ways of including visually impaired students in collective activities. The workplace application of musical skills in visually impaired students is a common, yet often complicated thing. The thesis may raise teachers? awareness of visually impaired children and the related educational options. It may also lead to deepening the topic of expanding one?s theoretical and practical knowledge.
