If you can play all major (ionian) and natural-minor (aeolian) scales, you can play already 24
of 84
. I think this is a rather big question asking for fingerings of all the left 60
ones. Also we are not talking about melodic or harmonic minor, which have 7
modes too, times 12
times 2
equals 168
modes.
Not to discourage you: With your ability of already playing 24 keys I would say you have a pretty good start.
Also as for the major or minor scales you have quite a few fingerings in common. For example in C major you can play all modes with:
RH: 123-1234(5)-123-1234(5) etc.
LH: 54321-321-4321-321 etc.
As a rule of thumb:
try to avoid the thumb on black keys!
As you play F major on the right hand with: 1234-123-1234-1234
to not get the thumb on the Bb
. As you know you can use the same fingering as for c major for the left hand in F major
As you mentioned the fingering for B flat major, you seem to be familiar with those fingerings that in the beginning need a little practice, but you should be able to adapt those to the modes too.
Not to forget:
"Fingering itself is an art, it needs time and practice."
For example: the fingering I wrote for the C major scale makes sense if you play from c to c, but what if you want to go one tone further and play from c to d? It surely depends on the run but here I would go this way:

the same applies for the modes too, as soon as you play more complex figures rather then just the scale from one octave to the other you might need to use different fingerings.
