Chromatic notes
Continuing to tune by 5ths to produce a fully chromatic scale will produce more leímmata
(semitones or minor 2nds of 90 cents) just above the top pitch of the 5th.
Edward Bunting mentions chromatic notes F# and C# only.
Adding 5th b-f#
5th b - 90 - c - 204 - d - 204 - e - 204 - f# = 702
G - 204 - a - 204 - b - 90 - c - 204 - d - 204 - e - 204 - f# - 90 - g = 1200
3rd G-b (408 cents) + 5th b-f# (702 cents) = 1110
so 2nd f#-g = 90 cents
Adding 5th f#-cc#
f# - 90 - g - 204 - aa - 204 - bb - 204 - cc# - 90 - dd - 204 - ee - 204 - ff#
5th f#-cc# (702 cents) + 3rd dd-ff# (408 cents) = 1110
so 2nd cc#-dd = 90 cents
Theoretically adding 5th c#-g#
c# - 90 - d - 204 - e - 204 - f# - 204 - g# - 90 - aa - 204 - bb -204 - cc#
5th c#-g# (702 cents) + 3rd aa-cc# (408 cents) = 1110
so 2nd g#-aa = 90 cents
Continuing to tune by 4ths will produce more leímmata just below the top pitch of the 4th.
Theoretically adding 4th f-bflat
4th f - 204 - g - 204 - a - 90 -bflat (498 cents)
Theoretically adding 4th bflat-eflat
4th bflat - 204 - c - 204 - d - 90 - eflat (498 cents)
