Brief explanation of temperaments
Temperament Keys
Limitless modulation of the key became available only after the invention of Equal temperament. When you use a
temperament other than Equal temperament, you must carefully choose the key to play in. For example, if the song you
are going to play is written in D major, choose "D" to set the temperament key.
Equal Temperament (Flat)
This is an "unstretched" equal temperament that divides the scale into twelve equal semitones. This produces the same
chordal intervals in all twelve keys, and has the advantage of limitless modulation of the key. However the tonality of
each key becomes less characteristic and no chord is in pure consonance.
Equal Temperament (Stretched)
This is the most popular piano temperament and is the initial setting. The hearing ability of a human is uneven and is not
as accurate with high frequency and low frequency as it is with the middle range. This temperament's tuning is stretched
to compensate for this so the sound will be heard naturally to the ears. This "Stretched" equal temperament is a practical
variation of the "unstretched" equal temperament which was invented on a mathematical basis.
