Roland HP-7/3 Tuning to other instruments’ Pitches Master Tuning, Changing the temperament, Tonic

Chapter 5. Changing Various Settings

■Tuning to other instruments’

pitches (Master Tuning)

In situations such as when playing ensemble with other instruments, you can tune the HP-7/3’s reference pitch to the pitch of another instrument. The standard pitch generally refers to the pitch of the note that’s played when you finger the middle A key. This tuning of all the instruments to a standard pitch is called “tuning.”

If you press the [Piano] button in step 2 of “Making Detailed Settings (Function)” (p. 33), a display like the following will appear.

The last three digits are indicated in the display. “440.0 Hz” is indicated in the figure above.

Value	415.3 Hz–440.0 Hz–466.2 Hz
Power-up default setting	440.0 Hz

This setting remains in effect until you turn off the power.

■Changing the temperament

You can play classical styles such as Baroque using historic temperaments (tuning methods).

Today, compositions are generally created with equal temperament in mind and are played using equal temperament. However in past ages of classical music, a variety of temperaments were used. Playing a composition with its original tuning lets you enjoy the sonorities of the chords that the composer originally intended.

If you press the [E.Piano] button in step 2 of “Making Detailed Settings (Function)” (p. 33), a display like the following will appear.

Temperament Tonic

You can choose from among the seven temperaments described below.

Dis-	Temper-	Qualities
play	ament
		In this tuning, each octave is divided
		into twelve equal steps. Every inter-
1	Equal	val produces about the same amount
		of slight dissonance. This setting is in
		effect when you turn on the power.

Dis-	Temper-	Qualities
play	ament
		This tuning, devised by the philoso-
		pher Pythagoras, eliminates disso-
2	Pythagor	nance in fourths and fifths.
	ean	Dissonance is produced by third-in-
		terval chords, but melodies are eu-
		phonious.
		This tuning eliminates ambiguities in
	Just	the fifths and thirds. It is unsuited to
3		playing melodies and cannot be
	Major
		transposed, but is capable of beauti-
		ful sonorities.
		The Just tunings differ from major
4	Just	and minor keys. You can get the
	Minor	same effect with the minor scale as
		with the major scale.
	Mean	This scale makes some compromises
5		in just intonation, enabling transposi-
	Tone
		tion to other keys.
		This temperament combines the
6	Werck-	Mean Tone and Pythagorean tun-
	meister	ings. Performances are possible in all
		keys (first technique, III).
		This is an improvement of the Mean
	Kirn-	Tone and Just tunings that provides a
7		high degree of freedom of modula-
	berger
		tion. Performances are possible in all
		keys (III).

Tonic

When playing with tuning other than equal temperament, you need to specify the keynote for tuning the song to be performed (that is, the note that corresponds to C for a major key or to A for a minor key).

While hold down the [E. Piano] button, and press a note to specify the desired tonic key.

The tonic note you specify will be displayed as follows.

If you choose an equal temperament, there’s no need to select

akeynote.

*If you record with a temperament other than equal temperament selected, and then want to play back that performance, use this setting to select the same temperament for playback as the temperament you used when recording.

*When performing in ensemble with other instruments, be aware that depending on the key, there may be some shifting of the pitch. Tune the HP-7/3 to the fundamental pitch of the other instruments.
