Intervalon 2D-Interval Explorer

Nature breezes What,  Row row row a boat,
vibrating in rings and arches;   Gently down the stream,
Listen straight up for  Merrily merrily merrily merrily Life is but
a Rainbow/Dream.

Intervalon is a musical instrument software that works on a Windows PC/tablet (technically a Win32 desktop application with Touch interface support).
It can be played by touch (best if you have a touch screen monitor or a tablet) / PC-keyboard keys (very good, mappings flexible) / a mouse.
I hope you enjoy playing it.
(You can jump to the download section dozens of lines below.)

It is subtitled 2D-Interval Explorer. Yes, try consider, please:
Musical intervals, a second, third, fifth, octave, and so on, are most easy when they are thought of as Two-Dimensional.
I say this because, traditionally intervals have been understood as 2D-like things, D# and Eb flatly discrete, but today too many people think just otherwise.

The idea of 2D Interval

Tune pitch heights of note-keys by way of 2D-Intervals.

Plot note-key points by way of pitch heights and 2D-Intervals, always linearly.

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).
It has 5th/4th and 3rds/6ths equally less pure.
   7/48 = ( (1/3 + 1/4) / 2 ) / 2     (This makes 5th 698.81867 cents.)
It seems fairly near to 1/7 (=7/49) comma meantone, but actually sounds very differently, kind of like a Just Intonation scale tuning.

Composers the author admires:

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