My music skills are insufficient to be of much use to you, but if all else fails, go to the Faculty of Music at the nearest university and ask to use the "Up-down" finder/ dictionary/ whatever they call it. They'll know what an "Up-down" is. Basically, you track each note change as either up, down, or same (U, D, or S) and it makes something that you can look up like a dictionary entry. If you hum the tune to them accurately, they can usually find it.

Example: Scots Wha' Hae is UDDUUU (grace notes don't count.)
