Try seems that Pythagoras is the first person to establish the consonant acoustic relationships between strings regarding proportional lengths

One factor in the newest rarity regarding Pythagoras unique offer try you to definitely Pythagorean degree is passed on from one age bracket to a higher by word out of mouth, as writing thing is actually scarce. Additionally, off esteem because of their commander, a few of the discoveries created by the brand new Pythagoreans was attributed to Pythagoras themselves; this will account fully for the term ‘Pythagoras’ Theorem’.
