Living and working in Johannesburg, South Africa at about 10,000 feet above sea level I find no noticiable difference in tone, but to be honest unless I took a piano down to the coast having recorded a sample or something...... Brian Lawson IC PTG What difference does this lower pressure make in the tone of a piano say when played at sea level and then played at 5,000 feet? Would it make any difference mountain folk?
