"Some settling and adjustment to local environment occurs of itself in this new piano. In addition, after a certain amount of use, the new felt and leathers "pack in" and cause minor changes in regulation. It is essential then' that any new instrument must be thoroughly tightened and re-regulated after certain period of use. The appropriate timing of this service would ordinarily fall somewhere between three months and 12 months after date of purcahse." - YAMAHA
