Members Steadfastly Posted August 16, 2011 Members Share Posted August 16, 2011 This may help. I'm an airplane mech. Take a small airplane like, say, a Cessna 150 with aluminum construction and steel flight control cables. As you go up in altitude the temperatures drop considerably. That means the flight control cables will get tighter right? Wrong. Aluminum expands and contracts more with temp changes than steel. So these cables actually become looser. The airplane has contracted more than the cables meaning less distance between the points contacting the cables.The wood in a guitar has way more mass than them skinny little strings. So they will contract more than that big guitar. So the exact opposite happens. A guitar warms up by coming in contact with your body. So this process reverses itself as you play. An excellent illustration! Link to comment Share on other sites More sharing options...
Members JTEES4 Posted August 16, 2011 Members Share Posted August 16, 2011 Humidity and temperature changes will do this. Link to comment Share on other sites More sharing options...
