This thesis examines the effects of a multi-methodological approach (theory, history, practice) to piano studies. The aim was to see how a deeper and more structured study would improve my piano playing. The study process was based on two specific compositions: Fantaisie-Impromptu, op.post.66 by the Polish composer Fryderyk Chopin and Clair de Lune, from Suite bergamasque by the French composer Claude Debussy. The compositions were executed and recorded in the first part of this project before the academic year 2020/2021, once from the middle part and twice from the final part of the project, spring 2021. Four recordings were done between June 2020 and the final concert in June 2021 and are all uploaded on the same YouTube channel, Pianist Sven. As a result, an improved efficiency and structure during piano practice sessions and when stud- ying theoretical aspects, has been obtained. Musically speaking, I got a better understanding of rhythm and tonality. The practical and theoretical studies carried out has helped me to create a methodological map to applicate in the future and to develop further.During the study of the specific subject, I created two handwritten paper posters. For achieving an increased readability of the thesis, images were uploaded on an own created website, called Chopin-vs-Debussy. I have conducted an interview with pianist and teacher, Giulio Biddau and inserted as part of the thesis (5.1.4) and of the website as well.
