Abstract

Notes produced by a conventional mechanical musical instrument played by a person contain natural variations which do not occur at discernable levels in music produced electronically. It is proposed to apply random or pseudo random variations to notes generated by electronic means to produce a more pleasing sound. The variations may affect the amplitude or frequency of the note or the length of time between successive notes and may be produced by use of amplitude modulation, frequency modulation or digital techniques.

Description

24 8054 Improved Perception of Electronic Music by the Application of
Random or Pseudo Random Variations to Notes.
Description
I am a musician. I find music played live is generally pleasant to listen to, but music produced electronically is often not. I believe that the brain consciously or subconsciously does not always fmd pleasant several nearly identical notes played at a constant beat (that is three or more notes that have no readily discernable difference between them in terms of the frequency of the notes, the amplitude shape of the notes and the time elapsed between subsequent notes), these series of notes typically produced by electronic and/or electromechanical means rather than being played on a mechanical instrument by a person. I believe that people perceive a series of notes that are closely repetitive (such as the background beat in a piece of played music) more pleasant and/or less irritating, either consciously or subconsciously, if the notes contain some variation. This occurs naturally when a conventional mechanical instrument is played by a person but does not occur at discernable levels in music produced electronically. I propose that music produced electronically containing repetitive notes or beats should introduce some random or pseudo random variability of the frequency and/or amplitude shape (amplitude modulation) and/or changes of frequency (frequency modulation) of repetitive notes and/or some random or pseudo random differences of time between successive notes. This random or pseudo random variability can be achieved by electronic means and applied to music produced electronically. I also propose that non-repetitive music produced electronically could be perceived by a listening person as more pleasant or less irritating if random or pseudo random variations are introduced into the mathematical relationship between some or all notes in terms of frequency and/or amplitude shape (amplitude modulation) and/or changes of frequency (frequency modulation) and/or of the time between notes. Such variations can be introduced into a system intended to produce electronic music by amplitude and frequency modulation techniques or by digital techniques.

Claims (1)

  1. Claims I claim originality in describing how music could be perceived by a
    listening person as more pleasant or less irritating if random or pseudo random variations are introduced into the sounds of notes of electronically produced and/or played music.
    I claim originality in describing how random or pseudo random variations can be applied electronically to the sounds of notes of electronically produced and/or played music by amplitude or frequency modulation techniques or digital techniques for the purpose of allowing the music to be perceived as more pleasant or less irritating a listener.
