Musical Relativity at the ArXiv blog

From the paper:

It is known that certain triads sound “happy”, while others sound “sad”.
Why this is so has been a question on minds of many musicologists, composers, musicians and
music lovers for a very long time and theories have been put forward. References to some works in
this area can be found in the recent book by Loy. But the question of “Why?” is beyond the scope
of this work. In this paper, we simply show that under specific physical conditions, a chord sounds
happy or sad depending not only on the observer’s subjective interpretation, but also on his frame
of reference. In other words, the musical “mood” depends on the observer’s state of motion.

In other words, “that note sounds flat!” becomes “you’re moving at the wrong speed!”
