The trick about music is the sheer unlimited variety it allows to experience time. We all think primarily of rhythm as the direct link between time and music. Then there are the additional annotations of composers on their scores like “lento” or “presto”. In addition each note has a frequency as swinging per second, which serves as the basis for synchronization of an orchestra. The length of each note or a each phrase of music evokes specific emotions in listeners. Human embryos even register music as the frequencies and duration travel across boundaries. The relationship of time and music is such a vast subject matter that the scope of this deserves to be studied across centuries, music periods as well as across cultures. Certainly, we find a few books on the subject beyond the simple physics of waves lengths and frequencies.
