Tuning
F2
Scale
In addition to the tuning method described on page 17, overall tuning can also be accom-
plished via the F1 function.
After selecting “F1”, use the [–/NO] and [+/YES] buttons to lower or raise the pitch in 0.2
Hz increments (the first time the [–/NO] or [+/YES] button is pressed simply switches to the
tuning value display without actually changing the tuning). The overall tuning range is from
427.0 Hz to 453.0 Hz (corresponding to the A3 note’s Hz). Press the [–/NO] and [+/YES]
buttons simultaneously to recall the default value: 440 Hz.
Tenths of a Hertz are indicated on the LED display by the appearance and position of one
or two dots, as in the following example:
In addition to the standard Equal Temperament tuning, the CLP-555 includes 6 classic
tunings that you can select and use to play music of the corresponding period, or experiment
with in a more modern context. The tunings are:
1: Equal Temperament
2: Pure Major
3: Pure Minor
4: Pythagorean
5: Mean Tone
6: Werckmeister
7: Kirnberger
After selecting “F2”, use the [–/NO] and [+/YES] buttons to select the number of the
desired tuning, then press the key corresponding to the key on which you want the selected
tuning to be based (unlike the Equal Temperament tuning, the classic tunings must be tuned to
a specific key). The selected key will appear on the display, followed by a low bar if flat (e.g.
“2d_”) or a high bar if sharp (e.g. “2F~”).
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default settings (Equal
Temperament tuning).
• No base key can be set for the 1: Equal Temperament tuning.
