plus.And the whole point sounds like learning that piece for a social situation they have in mind and to impress girls.
Doomed.Piano nerds don't impress girls. You gotta play bass guitar. Sorry to break it to you.On the other hand, it only takes a few minutes to learn bass.
Second, it is not true that women don't get impressed by pianists. They have the biggest instrument. They show the most impressing dexterity. They don't look ridiculous while they play. OK, so it also helps if they don't look like old horses or precocious progidies with big googles.
Teach them what they want. I get irritated with teachers who have some kind of ideal that all their students must abide by, art can be approached in so many ways and some people have to approach it in a real stupid manner to realize what is better in the future.
