Do you think so?I imagine it would be nice for playing many Dm tunes also.
First, are you thinking of D-dorian or D-minor?
D-Dorian really benefits from the C bell-note. F-natural or D-minor also make use of C.
Three options:
(1) C-flute could be a good choice... which is what a whistle player would reach for.
(2) F-flute, you would be typically be playing a G scale fingering (A-dorian or E-minor), which is fine.
(3) D-flute with C-foot. To play in D-dorian, F-major or D-minor on a D-flute, you need a C-foot and some practice with the F-nat and Bb keys.
I keep coming across really beautiful tunes in D-minor, D-dorian and F.
