This is a list of approximations for overtones in various equal temperaments. For space reasons octaves of already mentioned notes are not listed. For each base note the list shows the k-th harmonic up to a sufficiently large k and the frequency deviation in cents. Notes are highlighted with four different colors (green, yellow, orange, red) indicating distance to the maximum deviation (green = very good approximation)
