While writing this book at my home in San José, California, I have on several occasions heard an ice cream van drive down my street whose music is the melody of Mozart’s Ländler K. 606 no. 1 (Example 8.1). I may be the only person in the neighbourhood familiar with the original source of the music, which is obscure even in the context of the Viennese Classical repertoire. If I had not spent the past few years researching Viennese dance music I would not have been familiar with it either. This fact in itself raises issues pertinent to the broader issues discussed in the preceding chapters.
