Tuning Settings

Matching the Pitch with Other Instruments (Master Tuning)

When playing ensemble with other instruments and in other such instances, you can match the standard pitch to another instrument.

The standard pitch generally refers to the pitch of the note that’s played when you finger the middle A key. For a cleaner ensemble sound while performing with one or more other instruments, ensure that each instrument’s standard pitch is in tune with that of the other instruments. This tuning of all the instruments to a standard pitch is called “Tuning.”

Setting	Master tuning value
15.3–40.0–66.2	415.3 Hz – 440.0 Hz – 466.2 Hz

When the instrument is shipped from the factory, this is set to “440.0 Hz.”

Using a Piano’s Unique Tuning (Stretch Tuning)

Pianos are generally tuned so that the low range is flatter and the high range is sharper than equal tempered pitches. This method of tuning is unique to the piano, and is known as “stretched tuning.”

Setting	Description
	This tuning curve expands the bass and treble ends
On	somewhat. It is suitable for performances such as
	piano solos.
	This is the standard tuning curve. This is suitable for
OFF	when using Dual play (p. 31) or when playing in an
	ensemble with other instruments.

Adjusting the Tuning (Temperament)

You can play classical music such as baroque pieces using their original tuning.

Most modern songs are composed and played with the assumption that equal temperament (the most common tuning in use today) will be used, but when classical music was composed, there were a wide variety of other tuning systems in existence. Playing a composition with its original tuning lets you enjoy the sonorities of the chords that the composer originally intended.

Temperament Temperament key

Setting	Temperament	Qualities
		In this tuning, each octave is divided into twelve
1	Equal	equal steps. Every interval produces about the
		same amount of slight dissonance.
		This tuning eliminates ambiguities in the fifths
2	Just (Major)	and thirds. It is unsuited to playing melodies and
		cannot be transposed, but is capable of
		beautiful sonorities.
		The Just tunings differ from major and minor
3	Just (Minor)	keys. You can get the same effect with the minor
		scale as with the major scale.
4	Arabic	This tuning is suitable for the music of Arabia.
		This is an improvement of the Meantone and
5	Kirnberger	Just tunings that provides a high degree of
		freedom of modulation. Performances are
		possible in all keys (III).
6	Meantone	This scale makes some compromises in just
		intonation, enabling transposition to other keys.
		This tuning, devised by the philosopher
7	Pythagorean	Pythagoras, eliminates dissonance in fourths
		and fifths. Dissonance is produced by third-
		interval chords, but melodies are euphonious.
		This temperament combines the Meantone and
8	Werckmeister	Pythagorean tunings. Performances are
		possible in all keys (first technique, III).

Specifying the Temperament Key

When playing with tuning other than equal temperament, you need to specify the temperament key 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). If you choose an equal temperament, there’s no need to select a temperament key.

*When performing in ensemble with other instruments, be aware that depending on the key, there may be some shifting of the pitch. Tune the HP305/HP302 to the fundamental pitch of the other instruments.
