This page provides frequency tables for note lists. Pitch names follow the linear music code: a pound/hash sign (#) indicates a sharp while an exclamation point (!) indicates a flat.
The relevant unit of measurement for tunings is the cent.
In equal-tempered tunings, the ratio between two consecutive degrees of the chromatic scale is everywhere

The equal-tempered perfect fifth of 700 cents is 2 cents narrower than the ratio 3:2. The equal-tempered major third of 400 cents is 14 cents wider than the ratio 5:4.

According to the Wikipedia entry on Meantone Temperament, Pythagorean tuning generates “all non-octave intervals” from a “stack of perfect fifths”. Each of these fifths is tuned in an exact ratio of 3:2, or 702 cents. Table 2-1 details which ratios go with which pitch names.

Table 2-1: Ratios for Pythagorean tuning.
Notice that each successive ratio in the sequence C, G, D, A, E, B, F# adds a factor of 3 to the numerator; the denominator always being a power of 2. Similarly, each successive ratio in the sequence D, F, B!, E!, A!, D! G! adds a factor of 3 to the denominator; in these cases the numerators are always powers of 2. Notice also that F# and G! have different ratios. F# is sharper than G! by 23 cents.
The Pythagorean major third from C to E is 408 cents, which is 21 cents wider than the ratio 5:4.

According to Wikipedia, Meantone Temperament generates “generates all non-octave intervals from a stack of tempered perfect fifths” (italics mine). Meantone temperament has many flavors. These include equal temperament, where a perfect fifth has 700 cents, and Pythagorean tuning, where a perfect fifth has 702 cents. However the temperament most commonly referred to as “meantone” is the “quarter-comma” flavor, where a perfect fifth has 697 cents (5 cents narrow than the ratio 3:2).

Table 5-1: Ratios for 7-11 tuning.
I made up the just 7-11 tuning for the Note-List Instructions. I have no idea if anyone else has used it before and took no trouble to research the issue. My initial idea was to create a tuning with open consonances (ratios involving 3) and semi-consonances (ratios involving 7), but no soft consonances (ratios involving 5). Since this initial prescription produced only 9 ratios, I added in several ratios involving 11. The selected ratios are detailed in Table 6-1.
