Analysis of Time-Varying Spectrum of Pianos
 Smělý, Pavel ; Rajmic, Pavel (referee) ; Jirásek, Ondřej (advisor)
This work focuses on an analysis of a time-varying spectrum of pianos. The beginning of the work deals with the gradual evolution of the piano, aiming at timbre and design, and it analyzes in detail its individual parts and their influence on the sound spectrum. The theoretical part also concentrates on the issue of harmonic analysis in both the musical conception of timber and the usage of mathematical signal processing methods that make this analysis possible. Another part deals with practical tasks of the work such as a description of an application and functions created in the interface of MATLAB for exploring the time-varying spectrum of tones, description of the method and procedure of the measuring of three concert grand pianos. The work also analyzes, by supporting it with practical examples and by comparing the measured pianos, the most important acoustic phenomena that originate from the production of tones in the instrument; it describes the timber of individual instruments, and it gives recommendations.
