Enumerating Left Hand Forms for Guitar Tablatures Using Non-Decreasing Finger Numbers and Separators

We point out that fingering decisions of string instruments and other instruments differ in that the former involves string assignments as well as finger assignments while the latter is simply a matter of assigning fingers to notes. The present study introduces a three-level model for fingering decision of string instruments to describe the structure of the problem and present problem settings of fingering decision based on the model. as well as a new idea for enumeration of left hand forms for guitar tablatures using nondecreasing finger numbers and separators.
