How to train my ear
General mountain dulcimer or music discussions
@wally-venable, you are right that learning perfect pitch is not a reasonable goal, but to learn relative pitch should be.
Students in most formal music education programs develop tricks to learn intervals. The first two notes of "Happy Birthday" represent a 2nd. The first two notes of "When the Saints Go Marching In" represent a 3rd. The first two notes of "Here Comes the Bride" represent a 4th. The first two notes of "Twinkle Twinkle Little Star" represent a fifth. The first two notes of "My Bonnie Lies Over the Ocean" represent a 6th. I can't think of one for either the minor or major 7th, but I'm sure you can look one up since there must be lists like this all over the Internet. And the octave is "Somewhere Over the Rainbow."
I've stuck with the major scale (Ionian mode) here, but you could do this for the chromatic scale. The minor 2nd is the dangerous shark music from Jaws. The minor third is the first two notes of "Greensleeves." And the list goes on.

There's hope for me yet!!
