In this thesis I discuss, analyse and intend to answer the question: What is the best way to capture the sound of the acoustic accordion? It was my desire to explore this theme that led me to this research, and I believe that this question is important to many other accordionists as well. From the very beginning, I wanted the thesis to be not only an academic material but also that it can be used as an instruction manual, which could serve accordionists and others who are interested in this subject, to delve deeper into it, understand it and hopefully get answers to their questions about this subject. The thesis contains five main chapters: Amplifying of the accordion at live events, Processing of the accordion sound, Recording of the accordion in a studio - the specifics of recording of the accordion, Specific recording solutions and Examples of recording and amplifying of the accordion in practice of other accordion players, and two recordings: D. Scarlatti - Sonata D minor K 141, V. Trojan - The Collasped Cathedral. My aim is that this thesis will contribute to create a comprehensive insight into the specifics of capturing the accordion sound, contribute to better understanding of the acoustic properties of the instrument and bring practical answers to questions that many accordionists have. I have chosen to mention very basic technical aspects related to how to capture the sound of the acoustic accordion with respect to potential elementary knowledge of some people in this area. But, I also discuss very specific and professional details and focus on how different kinds of microphones can be used to capture the sound of the acoustic accordion. This is a subject that clearly is understudied and probably not has been a matter for proper research before. Most of my comments and analysis come from my personal experience and different experiments but there is also an interview included in the thesis with one very experienced accordionist who also is a professional music producer. I hope that my thesis will help other accordionists, sound engineers, and anyone else to understand the accordion and its specifics regarding both studio recording and live amplifying.
