In tuning, the '''logarithmic mean''', '''geometric mean''', or simply '''mean''' generates new pitch materials by taking the mean in the [[Wikipedia: Logarithmic scale|logarithmic scale]] i.e. pitch. It can be said with respect to frequencies or frequency ratios on a certain common fundamental.  
In tuning, the '''logarithmic mean''', '''geometric mean''', or simply '''mean''' generates new pitch materials by taking the mean in the [[Wikipedia: Logarithmic scale|logarithmic scale]] i.e. the scale of pitch. It can be said with respect to frequencies or frequency ratios on a certain common fundamental. The idea of treating [[quarter-comma meantone]] as the "strict" meantone is backed by this type of mean.
