string height

[reggaepass at aol.com]

Randy and List,

I really don't know what the reason is--or IF there is a reason (and 
it's not simply a coincidence in the case of these two instruments).  
However, with regard to your notion, please note that the lower 
pitched, longer strings are at a LOWER elevation in the tenor (compared 
to the higher pitched, shorter srings at the other end of the agraffes 
at the tenor/treble break) but HIGHER in the capo (compared to the 
other end of the capo at C8).

Alan,

Would it be that the lower/longer note take more blow distance  ie 
power to have a smooth transition and/or because the longer length of 
the wire being struck has a greater displacement? Interesting.

Hi Lists,

We recently measured string heights on a Steinway B and  Yamaha G2.  An 
astute assistant noticed that on both pianos the highest note 
(pitch-wise) in the tenor was higher than the lowest note in the tenor 
(more than can be explained by the gradual decrease in wire diameters, 
were the agraffes all level) and that the lowest note in the capo 
(pitch-wise) was higher than the highest note (C8).  Is it just a 
coincidence that we happen to measure two very different pianos with 
this same set-up, or is there an overarching design reason for this 
(making it a goal by design shared by many manufacturers)?



Thanks,



Alan Eder
