What happens when you switch
This is no longer a fine adjustment.
About 1,144 Cents measure small pitch differences: 100 cents make a semitone, 1 cent is barely audible. More about cents → . An octave is 1,200. So it falls a good 56 Cents measure small pitch differences: 100 cents make a semitone, 1 cent is barely audible. More about cents → short — a bit more than half a semitone. That’s the appeal of this number: almost the doubling, but noticeably off.
Origin
Where the name comes from
The syllables Ut, Re, Mi, Fa, Sol, La go back to Guido of Arezzo in the 11th century. He took the opening syllables of the lines of a Latin hymn and turned them into the first workable method for naming melodies, rather than just singing them back by ear. This “Ut–Re–Mi” became today’s “Do–Re–Mi”.
What Guido did not do: assign hertz values to these syllables. The term hertz did not exist at the time, and neither did a binding tuning standard. The assignment of specific frequencies to these syllables is considerably more recent and does not date back to the Middle Ages — it is often told that way, but the sources for it are modern.
