The document of the undergraduate thesis is a product of research and the use of available tools, concepts, and principles of software development. By developing a concrete software solution in which acquired knowledge was applied, the document addresses analysis, descriptions, and conclusions based on facts. The purpose of the implemented software solution, which is in the form of an Android mobile application, is to facilitate the process of researching resources needed for playing a song in the form of lyrics with chords or tablatures. The finding is made by taking a song sample using the microphone of a device. The Chordiato application also allows users to save and manage already recognized songs, making it even easier to retrieve wanted music sheet data. The whole solution is a simple tool intended for anyone who wants to play. The document starts with a thorough analysis of the used music recognition algorithm. Afterward, the usage of the application is presented, and its functionalities are described. The application is compared with existing similar solutions, and then the thorough development process description starts. Insight into the solution components is given, problems are explained, decomposed, and the process of solving them is explained.
