I'll comment on this later. For now it is enough to say that researchers have confirmed what many have long suspected:
"The diversity of transitions between note combinations – roughly speaking chords plus melodies – has consistently diminished in the past 50 years."There is some interesting background to go with this and I'll share some of it this afternoon. I have just a question for now: Do we blame the musicians or do we blame the audience?
The "timbre" of songs – the number of different tones they include, for example from different instruments – has also become narrower, he added.
