Basic Concept of the Data Base on Music and Sound Ⅱ: Frequency Analysis to Beethoven's Piano Sonatas

摘要

In our laboratory, the data base of music and sound are constructing, and the 1st movement of Beethoven's Piano sonata No. 5 is added to it. Existing MIDI data was acquired from the Internet and was provided as the input data into the open source software which can count each pitch of tone. As the result, the histogram showing how many notes of each pitch were used in the music, which have the similar meaning to that of spectrum, was obtained. The data base is expected to be applied to various real problems while the lowest pitch could not be estimated accurately. The sonata can be thought as psychologically and physiologically pleasant music.
