Fingerings can be encoded in Humdrum **fing spines:
Fingerings can be placed in any order of spines after a **kern spine for the
staff on which they should be displayed. Here is an example of including both
**fing and **dynam data for the same staff using
J.S. Bach cello suite no. 1 in G major, BWV 1007, Menuet II. The **fing and
**dynam spines can also be exchanged.
Chords
Fingerings for chord notes are separated by spaces.
Fingerings in chords should be sorted from low to high pitches for right-hand notes in piano music, while left-hand note fingerings should be sorted from high to low pitches.
Coloring fingerings with CSS

Using the CSS definition:
