 Both this and other re-entrant tunings, such as the "Marlow" tunings, are now used, as well as non re-entrant tunings such as the "Baroque"; nevertheless the advantage of the Yepes re-entrant tuning over the other tunings is that it provides sympathetic resonance over all the 12 notes of the scale while the rest do not.These tunings may also be used on related instruments, such as ten string electric and jazz guitars.The Venezuelan cuatro is a member of the guitar family, smaller in size and with four nylon strings.
