A six tone scale in which each note is placed a whole tone (2 notes) apart from its nearest neighbours...
...is mapped over 4 octaves to give 24 evenly spaced notes
The scale is then used to “quantise” the dataset, assigning each data point to a note in the scale

An arpeggio of the notes allows the daily yield curve to be played, in this case as an ascending sequence of notes. Yield curve inversions ripple downwards, providing a big melodic contrast
