sotto questo sole da deserto e aspettando la partita di stasera, mi trovo a chiederti un parere in base alla tua grande esperienza.
I happened to try a Yamaha C3, which particularly interested me due to the tuning of the duplex scale.
I should preface that both the tuning and the timbre of the piano were satisfactory and everything responded well. Then, out of curiosity, I plucked the resonators with my fingers and, to my surprise, I noticed that the duplex scales were tuned to the interval of a major ninth.
Until today, I had only found duplex scales tuned to the fifth and the octave.
Is it frequent to find resonators tuned to the major ninth?
Dearest piano tuner, I am Saverio, I am looking forward to your video tutorials on repair and tuning work; you would be giving me a great GIFT, given my unquenchable passion for this immortal instrument.
THANK YOU and COMPLIMENTS! Ciaoooooooooooo saverio
Mmmmm it seems strange to me, why cancel the duplex scale which, if well tuned, produces resonant effects that pair well with the primary sound? Among other things, by tuning it to the octave one exploits the most powerful harmonic which generates a certain resonant strength; at the fifth we already begin to lose it. The major ninth is the ninth overtone generated from the fundamental... It seems absurd as an argument to me. In general, resonance is not generated on the same struck string anyway, but sympathetic vibrations are certainly generated in the duplex scale strings tuned to the octave and the fifth; therefore, it's not that by tuning to the major ninth one avoids using the duplex scale, and if that were the intent, then it would have been better to tune to the major seventh which is the fifteenth overtone, perhaps its use is slightly limited.... Well, it would be interesting to hear the explanation of the tuner who first tuned that instrument.
