Intervalon 2D-Interval Explorer

Intervalon is a musical instrument software that works on a Windows PC/tablet, with touch interface support (Win32 desktop application).
It can be played by touch (best if you have a touch screen monitor or a tablet) / PC-keyboard keys (mappings flexible) / a mouse.
I have put many amazements into it, hopefully to be found and appreciated by you.
And It is subtitled 2D-Interval Explorer. What? 2D Interval?

The idea of 2D Interval

Intervalon is designed to be very true to it.

Meantone the author uses most often:

7/48-comma meantone.
It is just in between of Pythagorean Tuning (with pure 5th) and 2/7 Meantone which is in turn just in between of 1/4 Meantone (with pure Maj.3rd) and 1/3 Meantone (with pure Min.3rd).
   7/48 = ( (1/3 + 1/4) / 2 ) / 2     (This makes 5th 698.81867 cents, fairly near to 1/7 (=7/49) comma meantone.)
It has 5th/4th and 3rds/6ths equally less pure, supposedly making intervals 2D-ness most protected.  It is so sweet.
(N.B. here, Meantone is not a means to approximate Just-Intonation singing/playing.)
From the viewpoint, 12-tone equal temperament (as a kind of Meantone) has 5th too pure, and tends to single-dimensioned-ness too much.


the author's most favorite composers:

Palestrina, Alessandro Scarlatti,  Handel,
Beethoven, Muzio Clementi,
Brahms, Mahler, Manuel de Falla, Furtwängler
