Selecting a temperament

There are numerous classical compositions that were composed using tempera- ments that differ from the “equal temperament” commonly used today.In order to reproduce the original sound of such compositions, the SP-250 provides Kirnberger and Werckmeister classical temperaments, in addition to the equal temperament, allowing you to select from a total of three temperaments.

To select one of the available temperaments, hold down the TOUCH button, then press the button corresponding to the desired temperament. To return to the equal tuning hold down the TOUCH button, then press the sound selection button whose LED is lit.

Button	Temperament
Both LEDs	Equal temperament. Nearly all keyboard instruments today use equal
turned off	temperament. This temperament spaces all semitones at equal dis-
	tances, and allows identical scales to be played in any key.
HARPSI/CLAV	Werckmeister. This is the Werckmeister III scale invented by Andreas
	Werckmeister, the German organist and music theoretician. This scale
	was created in the later Baroque period to allow relatively free transposi-
	tion.
VIBES/GUITAR	Kirnberger. This is the Kirnberger III scale invented by Johann Phillip
	Kirnberger in the early 18th century, and is used mainly for tuning harpsi-
	chords.
