Chaning Inharmonicity

[Isaac OLEG SIMANOT]

Its the hammers that change with season too.

Mostly !


Take five techs and have them knock on a table with a finger, they all will
have their own knock !
(Yamaha trick to undestand the importance of the playang hand when tuning)
Have a nice day anyone !
