- Description:
'The let-off', an essential component of the piano mechanism, is the point at which the hammer disengages from 'the jack of the upright piano and flies freely to strike the strings. It requires optimal positioning: a large 'let-off' makes it challenging to play pianissimo, execute rapid trills, or play powerful fortes, while a too small let-off might pinch sound, or even block specific notes.
'The let-off' buttons, for an undetermined reason, was excessively pulled out from the wood plank - causing it to engage later than required by the mechanical standard of the upright piano there. The late engagement results in the hammer not returning to its original position after striking the string. Consequently, it remains close to the string, creating a slight buzzing noise sound. Sounds 'the let-off' is way too close and the hammers are blocking. Easy enough fix if you have the right tool, trickier but still doable if not.
How fix it:
Max propose a workaround using a simple object, such as a hook, a spoke, or a thin stick even. This tool should be inserted into the adjustment screw ring of 'the let-off' of the upright piano and turned it clockwise.
Ultimately, we can manage to restore the full functionality of the upright piano hammer. It now returns to its must necessary starting position after striking the string, thus correcting the identified issue.
As the famous saying goes, "It doesn't matter what color a cat is, as long as it catches mice." In this case, the focus is not on the method used but on the successful outcome - the full restoration of the upright piano's 'THE LET- OFF'.
