10 string guitar set according to Yepes

F#G#ACEADgbe tuning for 10-strings Classical guitar (65-66 cm scale)

This special tuning was conceived by Spanish classical guitarist Narciso Yepes, considered one of the finest virtuoso of the twentieth century, and is used on a 10-string guitar. The real extension of this tuning of the tuning is that of a 7-string, with the seventh string being the lowest and the remaining (8th to 10th) using a re-entrant tuning, as shown on the following image (source Wikipedia).
