Without Reading Music by Daniel Levitinmi am fascinated reading and trying to figure out how to seize and be born as a noble art of music in mind. A few months ago has left a well interesssante suAmadeus article on the same topic. A concise summary although a bit of everything, lets just say wow. Each note of our system
musicalerisulta our ears separated by regular intervals. Going the distance between a note and the next it seems the same. The frequency of each note in our system is 6% more than the previous year. Our auditory system is sensitive to changes in both relative and proportional. Each tone is 6% more than the previous a rising tone of this amount 12 times so you double the original frequency (the exact proportion is the twelfth root of two: 1.05946 ..). Our brain is then able to calculate even in an unconscious way the tonic "recording how many times certain notes are played and where they appear in what order, reports.
Since children have absorbed passively listening to the stair structure is not an innate conscience but depends on the particular culture in which we have developed our neural circuits and synapses.
Surprising too is the fact that the pitch we perceive is not the real one given by the instrument to vibrate air molecules, but the most frequently Bassal key, all other frequencies are called overtones , and if one of the fundamental branoeliminiamo riprisina our brain, as all the higher frequencies increase by double, triple and so on. In a passage in which they played the harmonic series 200Hz, 400Hz, 600Hz, 800Hz 200Hz estimated that there may be fundamental, but the 100Hz. In one experiment it was noted that the firing rate of neurons in the inferior colliculus in the barn had the same speed of key missing, and linking the elettrodoa unamplificatoreveniveriprodotto in practice the same song heard.
now I propose that a listening
