There's a lot to be said for music that indulges different emotions. I've had what sound like similar 'discussions' with my father for the last ten years. He's been an army bandmaster near enough all his life, has played trumpet in Brass bands and Orchestras since he was 16, and is generally an all-round know-it-all on that entire sphere of music. The depths of his forays into 'pop music' are essentially Joni Mitchell and The Beatles. That's potentially a little unfair but I'm setting up the anecdote so you get my bias, naturally
We can get along just fine. We can sit in my car and he can find hours of music he'll happily listen to and constantly remark how impressed he is to see I've got some particular piece or album on my mp3 player. I think he wet himself when he found Sibelius 5 on there. And yet, the second something else comes on - and I have a huge range of tastes in music, I've got stuff I don't even know the latest genre name its given - he goes completely cold, shocked and appalled I could find such 'trash' worth listening to. What develops are more arguments than discussions, because he doesn't actually listen to my point or my music enough to actually consider them.
Now, admittedly, I find the kind of things you'll find in the Top 40 charts as played by Radio 1 completely unremarkable, but then that's fine, because I don't think Beyoncé is trying to appeal to me. It DOES irk me that my dad cannot understand that I enjoy music he 'doesn't get' - take something like Daft Punk. It's electronic, repetitive, musically very basic, but when I'm in the gym I don't want to hear Paul Desmond's dulcet tones mellifluously floating into my ears, apparently defying time itself as he slots beautiful phrasing in around whatever strange time signatures and rhythms Brubeck is playing - I want to hear something that pumps along with a very hard groove. I don't want to be intellectually engaged by what I'm hearing, I just want to be driven on by it. Different music for different moods.
I can't listen to jazz with 95% of my friends. Of the ..50% of them that would class themselves as 'obsessed with music', nearly all of those are into it for the scene and the skinny jeans and the festival wrist bands they can keep on for weeks after Glasto finished. They don't play an instrument, and I can't imagine what it's like to hear music without actually understanding the chords and harmonies behind it all, but I can totally see why millions of people love the very 'musically meritless' stuff if the lyrics or the beat offer enough for them to get something out of it. Or, in many cases, the 'image'.
Kind of huge topic (and slightly off the original, sorry!) but I had to throw in my two pence for your daughter's plight
On-topic, I loved the video, I always enjoy playing with chords with non-musical friends and seeing their faces when they realise just how common some progressions are.
