[HG] Upside down tangents

[Seth Hamon]

Ok, I'm newly bit by the hurdy gurdy bug so I'm researching and listening and 
reading everything I can get my hands on... 
   
  My question is could the tangents for the white/top keys be placed on the 
underside of the keys, or upside down from the bottom row of keys.. I thought 
of this because I saw a gurdy that looked like It couldn't be upgraded to be 
fully chromatic because their wasn't enough room for the tangents unless they 
were on the under side... Am I was off base here or has someone done this 
before.. Just a thought.... Seth
