Tonal Analysis
Alexander Lerch · 2022
Tonal aspects play an important role in understanding and analyzing music, as can be seen from the vast number of pitch-related publications in music theory. Pitches are the basic building blocks of key, melody, and harmony in music. The human perception of pitch is directly related to the frequency of a sinusoidal in the way that higher frequencies will lead to the perception of a higher pitch. Much can be said about pitch-related properties of music, covering not only the frequency mapping of specific pitches but also interaction of pitches in chords and melodies, harmony progression, and musical key. Fundamental frequency detection aims at detecting the fundamental frequencies in an audio recording. The tuning frequency may change over the course of a performance or a recording session. The chapter focuses on its use for chord recognition. Chord-inherent pitches can be doubled in different octaves without changing the chord type.
