Pianos offer pianists only a limited amount of freedom; indeed, apart from the pedals, the pianist’s scope for expression is limited to the 10 mm travel of each of the 88 keys on the keyboard. Even so, the combination of the pedals with the speed and velocity applied to the keys produces a range of tonal changes so broad that they cannot be reproduced with current digital technology. This is the true soul of an acoustic instrument, allowing the pianist to obtain an incredible amount of expression from just 10 mm of key travel.That is precisely why Yamaha devotes so much time voicing their pianos so that the intentions of the pianist are conveyed to the strings. In regulation, a craftsman adjusts the movement of the action so that it accurately transmits every nuance of the pianist’s touch. In voicing, the hammers, which cause the strings to emit sound, are pricked with a pick to create a balanced tone that will respond beautifully when played. Even today, in an era when technology continues to evolve rapidly, these tasks remain the domain of skilled craftsmen who must ensure the high quality of these instruments, and are the main reason that Yamaha has remained one of the top piano makers in the world.
