I have learned to do the test as you described above, everything is = clear as clear can be and yet, the tone improves!!!! To all! Please try for yourself, I think that is the definite proof. Just consider this: my teacher at the time in Japan was the famous = Tsuji-San (they call him over there "the great one"), he did not have the answer! And of course I have gone into this deeply myself but have given up = untill I was able to put my questions before you Cyber List Scribers! I am sure we'll find it.. friendly greetings from: Andr=E9 Oorebeek CONCERT PIANO SERVICE Amsterdam, the Netherlands email: oorebeek@euronet.nl =83 where MUSIC is no harm can be =83
