Zack and Kyra are both practicing their instruments at the same time. It’s an interesting mix of music because Kyra is in her fourth year of flute while Zack is in his fourth week of French horn. So there’s a nice gentle lilting of the flute, overpowered by the three brassy obnoxious notes that Zack knows. I imagine in a few years they maybe able to play a nice duet (although I’m not zure if there are duets for that particular pair of instruments) but for now it’s pretty comical.
