Let me just be sure I have this correctly: You want to contact your late drum teacher's daughter and offer, for a negotiated fee, to provide her with memories/anecdotes of the time you spent as her father's student?
I don't think it's intellectual property considering that her father was also involved in those memories. Expect the possibility of her hanging up the phone on you after asking. Maybe, maybe not! Typically in a situation like this, they are the ones to contact you (because they feel that your information is valuable) and not vice versa. Hope it works out though!
