Currently most popular piano tuning scale. PureMajor/PureMinor Based on natural overtones, three major chords using these scales produce a beautiful, pure sound. Pythagorean This scale, designed by Pythagoras, a Greek philosopher, is based on the interval of a perfect 5th. The 3rd produces swells, but the 4th and 5th are beautiful and suitable for some leads. MeanTone This scale is an improvement of the Pythagorean in that the swell of the 3rd has been eliminated. It spread during the late 16th century through the late 18th century. Handel used this scale. Werckmeister/Kirnberger These scales combine Mean Tone and Pythagorean in different ways. With these scales, modulation changes the impression and feel of the songs. They were often used in the era of Bach and Beethoven. They are also often used now to reproduce the music of that era on harpsichords. Normal setting: Equal If you select a scale other than Equal, you need to specify the root note using the B [-][+] buttons.
