The eyes have it : - )

Garret, I would suggest that you don't try to make one pair of glasses serve all your needs.  I realize it is an extra expense, but I would get a second pair of glasses for "work only".  These would be glasses that you only use for working, not for driving.  Imagine trifocals.  Now discard the upper "distance" section of the trifocals and expand the middle section to become the new upper section.  Now you have bifocals where the upper section is good for distances of about 2 feet and the lower section is good for distances of about 12-16 inches.  Why waste precious viewing area for distance vision when there is no need for distance vision while you are working on a piano?  I have a good relationship with my optometrist.  When I go for a perscription, I tell him exactly how I intend to use these glasses, and what distances I want to be in focus, and he writes a perscription for me at no additional charge.

Or, if don't have bad astigmatism, you might be lucky and find that some cheap off-the-shelf reading glasses will be suitable for special uses, like adjusting grand dampers, where you can't tip your head back far enough to make use of the lower section of bifocals.
