"An important
study for all performers concerned with the relevance
of the five-course guitar. (...) The biggest virtue of Eisenhardt's book is its careful,
thorough analysis of the complexities encountered when
performing solo music for the five-course guitar. It also
goes a long way towards addressing the implications
of stringing choice and instrumental technique for the
performance of a vast repertory - comprising some 180
printed and manuscript sources of solo music, plus more
than 250 sources of vocal music with alfabeto from Italy
alone - the bulk of which remains unknown to the modern
listener."
