I had sworn off software, back breaking work

But, having picked up a guitar, I got my tap measure out and reverse engineered the fret arithmetic.

Half tone count as some ratio the Nth power, where N counts half steps.  12 steps double the frequency, take the 12 root and we can construct all the 13 octaves by frequency. When doing this the perfect pitch step is a 1.5 ratio, or close enough.

So, having done this on my spread sheet, I got the bug, I want to construct chords out of those tones.  The spreadsheet is, after all, a perfect data base to construct all sort of chords and scale patterns.  So, my spreadsheet will become an awkward electronic organ.  Not going far, will quit soon.
