FYI, I recall the Mehegan books on jazz improvisation applying enharmonic 
equivalents freely. The Blatter books on instrumentation suggests applying them 
to simplify for harpists, which will save time and money. But orchestral 
instruments depart from Pythagorean tuning, not E12, so they are not 
equivalent, differing by a comma of about 20 cents.
