In music, '''27 equal temperament''', called '''27-tet''', '''27-edo''', or '''27-et''', is the scale derived by dividing the octave into 27 equally large steps. Each step represents a frequency ratio of the 27th root of 2, or 44.44 cents. | In music, '''27 equal temperament''', called '''27-tet''', '''27-edo''', or '''27-et''', is the scale derived by dividing the octave into 27 equally large steps.
