So this is a Dm chord all the way, though there could be a hint of Am every so often.
main riff is something like
F[sub]4[/sub]-A[sub]4[/sub]-F[sub]4[/sub]-A[sub]4[/sub]-D[sub]4[/sub]-A[sub]4[/sub]-E[sub]4[/sub]-A[sub]4[/sub]
and a variation sounds like this
F[sub]4[/sub]-A[sub]4[/sub]-E[sub]4[/sub]-A[sub]4[/sub]-D[sub]4[/sub]-A[sub]4[/sub]-D[sub]4[/sub]-A[sub]4[/sub]
caveat about octave numbers
Middle C= MIDI NN 60 = C[sub]3[/sub] in most daws = C[sub]5[/sub] in Fl
add 2 to the octave number for this to work right in fl
