Is it acceptable to dedicate a piece of music one has written to someone posthumously, if one has not met the person one is dedicating the piece to? I would like to dedicate a composition of mine to the father of someone very close to me, but I never met him, and I'm not sure if that would be frowned upon. In any case, if it is not a faux pas, should I ask permission of the family of the deceased first? Finally, how should the dedication be phrased (e.g., "To the memory of"; "To [name], 1949-2006"; etc.)?
