Gorgeous. I sometimes listen to foreign radio stations, wooed by the music and play of emotion in a singer's voice without understanding or necessarily needing to understand the words. Scent and music can both be powerful emotional triggers. Lovely comparison.

I like the suggestion of synaesthesia in this – that music and words might have their own 'scent' too, or a trace of something indefinable. Interestingly it works if the fragment and phrase are reversed …

… but that creates a slightly more melancholic feel for me… perhaps because there's more emphasis on what's not understood, by having it first. And closing with the scent invokes longing.
How scent evokes memories. I remember a song when I was a student in France and tried to find it for years. As soon as I did, I was transported back to my fifteen year old self. This haiku reminds me of that.
