Him - Nah!

ElderChild brought her music assignment home.  She plays tenor sax and was required to select a piece of music to work on, and then present to her teacher for evaluation next month.  She brought home a selection from the Harry Potter movies.  The scores came with the sheet music plus a CD that played both music-with-sax, and a no-sax play-along version.  She was having difficulties deciding between 2 pieces.  I asked her the names, to give myself a reference, and one was a "him-nah!".  ... What?  "It says 'Him-nah'!" ... I pondered this a moment and asked her if it was anything like a "yaatchet"  ... she was confused.  I asked her to spell "him-nah". ... So she did.  "H-Y-M-N." ... "Hun, that says 'Yaatchet'... but we pronounce it 'him'..." .... Been teasing her ever since, that she's playing the "Yaatchet-song"...
