EUROGRAND

5.6.2 Soft pedal intensity

Use this function to adjust the intensity of the soft pedal effect.

+Please enter EDIT mode (see chapter 5.1) and select the following function.

Function:

E4.2

 

Value:

1 ...

5

Description:

 

 

3:Normal soft pedal intensity (default setting)

1:Low soft pedal intensity

5:High soft pedal intensity

+The function will be effective only if the left pedal is used as a soft pedal, but NOT to start/stop the music sequencer (see chapter 5.5.8).

5.6.3 Fine tuning

The EUROGRAND can be detuned slightly to adapt it to other instruments or tunings. The setting made here affects the pitch of all keys.

The following section describes how to adjust the fine tuning of the EUROGRAND. The tuning shown in the display is referenced to the concert pitch „A" in Hertz (Hz).

5.6.4 Tunings

The EUROGRAND provides different tunings developed during the past few centuries. The tuning used most often today is called equal tuning and has been a characteristic element of the music composed from the 19th century up to the present. However, for some baroque pieces (e.g. by J. S. Bach) it can be interesting to use an older tuning system.

In the history of music, the development of the individual tunings can be traced back to the development of scales and polyphony and the resulting adaptation of instruments and their tuning. Apart from these historical reasons the limited tuning aids available in former times played an important role for the practical implementation of tunings.

The EUROGRAND 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 conse- quence, 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

With the exception of equal tuning, all tunings must be marked by a basic note.

Here’s how to set the basic note:

Value: C ... B

Description:

Altered notes are marked by dashes above or below the note name. A dash above the note name raises a note, a dash below the note lowers it.
