Both reply 1 and reply 2 are good advice. I find MPC's hard to understand, however, and I'm not sure if the use of the accent > really gives as much expression as Don wants.
Another way, then, similar to both these techniques, is to just use hidden dynamics.
Put f or ff immediately before the first note in the group, then hide it. Then put p or pp immediately before the second note, and hide it. MPC is probably preferable, but as I say, I am never sure I can handle the MPC.
Since it will be tedious to do the exercise many times, I agree the copying of the figure, and adjusting the pitch as needed, is a good approach.
how does one hide a dynamic?
