Because the (twelfth root of two) mathematical ratios of equal temperament are not exactly in tune (in both the scientific and
historic sense of whole number ratios between all the twelve musical intervals in the chromatic scale - and particularly for
major thirds, fourths and fifths), many performers of fixed tuned instruments, such as harpsichords and organs, prefer to have
the instrument tuned so that certain keys and intervals sound more perfectly in tune and "sweeter" to their ears and those of
the audience.
Many musical history scholars claim that music composed prior to 1850 should be performed with historically specific
non-equal temperaments so that contemporary performances of this music will sound more exact to the audible intentions
of the composers. Tuning an instrument so that a particular key, or certain keys, sound in distinctly good tune while other
keys sound somewhat more roughly in tune (or have one or more completely unacceptable "wolf" keys) is known as tuning
in non-equal temperament. Use the following steps to select a non-equal temperament from the preprogrammed tables in
the Strobe Center 5000:
