20EUROGRAND EG2280USB/EG8280USB User Manual

The EG2280USB/EG8280USB provides the following tunings:

•Equal tuning (default setting)

Equal tuning divides one octave into twelve intervals of equal size or spacing. Thus, each half-tone is detuned slightly to the same extent, with the octave being the only perfect interval. This has been the most common tuning since the 19th century, as it makes it possible to play all twelve major/minor keys.

•Pure major/minor intonation

This tuning is based on the perfect tuning of the seven notes of one scale

(e.g. C major). Triads played one fifth above or below are also perfect, since they use the notes of the basic key. However, all other keys are not playable, since their frequency relationships change depending on the basic note.

This tuning can only be used for music that strictly follows a classical cadence comprising tonic, dominant and subdominant.

•Pythagorean tuning

The Pythagorean tuning is based on perfect fifths. As a consequence, all thirds are impure.

This tuning was used for early music up to the late Middle Ages. The homophonic or two-part polyphonic music of the time did not use any thirds, but only perfect unison, fourth, fifth and octave intervals.

•Meantone tuning

Meantone tuning resulted from the change in the perception of dissonant intervals during the Renaissance period and from the beginnings of chromaticism and polyphony. Polyphony made the third the most important interval in music. Therefore, meantone tuning is based on perfect thirds rather than perfect fifths to tune the twelve notes of a scale. However, this also means that some scales are unplayable.

Today, the meantone tuning can still be used for works from the early 16th and 17th centuries (e.g. G. F. Handel).

•Werckmeister/Kirnberger tuning

The Werkmeister and Kirnberger tunings result from first attempts to realize a well-tempered tuning which – unlike the Pythagorean and meantone tunings

–allows for playing in all twelve keys. The advantages of the Pythagorean and meantone tunings, i.e. the slight detuning of some fifth intervals, have also been included in the Werkmeister/Kirnberger tunings.

Both tunings are interesting to use for works from the baroque period (e.g. J. S. Bach). Werkmeister is a popular tuning for organ works.

The following section describes how to change the tuning of the EG2280USB/EG8280USB.

5.6.5 Saving parameter settings

The EG2280USB/EG8280USB allows you to save the changes made to the instrument’s settings, so that they won’t get lost when the unit is powered down. When the save function is not active, all changes made to the settings – except for the music sequencer data – will be lost when you switch the piano off. When switched back on, the EG2280USB/EG8280USB recalls the factory default settings.

The save function can be activated separately for the following groups of functions: sounds, MIDI, tuning and damper pedal.
