My first experience in 10 String Guitar, shown to me by Li Zhao (China) my former student from Yamaha Music Academy (Kelana Jaya). He came to visit me in Feb 2019 and surprised me with this instrument.. The additional strings are mainly used for open strings which gives the extra resonance to the bass line. Most 10-string classical guitars are tuned in the style of Nasrciso Yepes (E, B, G, D, A, E, C, A#, G#, F#). This unusual tuning helps increase resonance of those notes which a normal six-string guitar do not normally generate.
