Easi-ER, not always easy. There is always editing to do, plus there may need to be additional changes depending on the instruments involved, any possible transitions in or out of incidental music, dance arrangements, etc.
Generally, keys are not changed unless it's really warranted, so if Voytko is comfortable in Foster's keys, nothing changes. That said, alternate keys are not uncommon at all. It's really a case-by-case thing. |
