Just about any adult that comes in contact with tweens, teens and young adults today, all agree the modern day music is nothing but loud and tasteless melodies.
Research conducted in Spain analyzed an archive known as the Million Song Dataset that is capable of breaking down audio and lyrical content into data that can be crunched to assess pop songs from 1955 to 2010.
According to lead artificial intelligence specialist Joan Serra at the Spanish National Research Councila, through complex algorithms, it was discovered pop songs have become essentially louder and blander in the sense of the chords, melodies and styles of sound used.
Serra found evidence of a progressive homogenization of the musical language.
He told Reuters, "In particular, we obtained numerical indicators that the diversity of transitions between note combinations - roughly speaking chords plus melodies - has consistently diminished in the last 50 years."
Not only has the style of music decreased, but also the timbre palette correspondingly lacks substance. The same note that may be played on instruments such as a piano or guitar is said to have a different timbre, proposing that modern day pop is limited in a variety of sounds compared to 50 years ago.
The study also demonstrated the loudness in music is due to the volume that is baked into a song during recording, which can make it sound louder even when it is being played at the same volume setting on an amplifier.
Many experts have long accused recording companies for spiking the volume in which songs are recorded but this is the first time evidence is available that confirms that theory.
Some believe old tunes that are re-recorded with increased loudness, simpler chord progressions and different instruments can make old sounds new and fashionable. The future of pop music may be found in the past.
