it is certainly possible to tune a piano
so that every interval is close enough to
the 12th root of 2 ratio
that;s how they do it - that;s 'the system'
if you do that, there is no reason for any
key to sound out of tune more than another
that is the very reason for the
'equal tempered' scale
[yes i know that is an irrational number
but the ear doesn;t have infinite resolution.]
[and yes i also know that on a piano, which
has a 7 octave range, the very highest and
lowest notes have to be made somewhat sharper
than 'correct' notes, because the actual
correct ones sound flat - but that;s not
what he was talking
about]
Thanks for all the replies. I guess I am like Ron since my world used to be a 5 string and a bass fiddle. Throw on a capo on the 5 string and play the same song in a different key.
So the bottom line here, if I am reading this right is, If you like a song, find out what key its in and then grab the box that can play in that key. If that is correct,what key boxes do you guys that perform have?
Thanks again for your patience in this matter as I dont have a lick of music training.
