One of the more fascinating parts to me was how little it took:
"If you're like 50 milliseconds too early, 50 milliseconds too late, then the storing mechanism actually doesn't work."
- sp332 9y agoThe cycles are 12 Hz, which is only ~80 ms between pulses. So 40 ms is exactly out of phase.
- jgtrosh 9y agoIf I understand the article, it's the slow waves that have the strong correlation, and those are described as being around one per second. Fifty milliseconds is then around a tenth of the half period, so that does implies a rather important timing precision needed.
- hathawsh 9y agoFascinating indeed. That's not very different from the timing of common music. Could it be that our appreciation of music is somehow related to the way our brains work?
- yesenadam 9y agoHmm.. which common music? I like really fast music (e.g. Coltrane, Charlie Parker) and really slow (Rachmaninov 2nd Symphony, Mahler Adagietto).
- Will_Parker 9y agoThe artists still produced music in tempos quite within the range of human heartbeats and / or breathing.
- stevemk14ebr 9y agoI think music's appeal is related to the rythmns of heartbeats. Logic being you find comfort in being close to another human, an advantage to be in pairs. Therefore the brain is hardwired to prefer rythmns around that pace. Just my theory though
- fuzzfactor 9y agoOne of the most popular recordings of the 20th century was basically in tempo with the resting human heart, with just that intro. "The Dark Side of the Moon" by Pink Floyd
- TimTheTinker 9y agoPerhaps (at-rest) heart beats and stem-level brain waves operate at the same frequency?
- hypertexthero 9y agoYes. See Harmonic Experience: Tonal Harmony from Its Natural Origins to Its Modern Expression by W.A. Mathieu https://www.goodreads.com/book/show/114365.Harmonic_Experience https://www.goodreads.com/book/show/114365.Harmonic_Experien...
- agumonkey 9y agoI strongly believe the many appeals of music is deeply related to many brain functions. As a drummer, polyrythms have altered the way I sense space, balance and time. Playing sophisticated patterns requires fine quantization of time and distributed coordination in all limbs. When you reach this you basically become better at many kinds of kinematics. You have finer control of each movements and a more abstract interpretation of the balance and state of all your limbs. It's not hard to see how valuable this would be for an animal. Learning harmonization also tickles the brain deeply (try to isolate a 7th counterpoint like melody and enjoy the bliss).
