A system giving the optimal chord-form sequence for playing a guitar

For biginners fingering for playing chords is more complicated and difficult than playing single melodies who chose a chord book, supporting device or any software to learn chord patterns. But these aids do not provide optimal result. A system that yields the optimal chord-form sequence minimizing the finger loads is proposed. The system YG (You are never afraid of a Guitar) gives a solution by giving optimal chord-form sequence evaluating difficulties of dynamic chord change between consecutive chords, physical realizability and note sufficiencies. To prune out impossible or ill-functioned chord-forms, chord constraints and finguring constraints are applied. The performance is experimentally evaluated, compared and is found to be the easiest.
