Ric, Jorgensen's _Tuning_ being right next to me, "Equal-beating temperament: any temperament that contains two or more intervals that beat exactly the same speed. In this case, the intervals can never be the same size." (glossary, p771) A search of the pianotech archives leads me to believe that this definition is more strict than what may be accepted, since I would interpret the above as meaning different intervals (ie. octaves and fifths, fourths and fifths, etc.). Conrad, could you let me know which cultures would consider what I do as normal? (Michael:"Are you going to leave those little pink and brown blocks on the keyboard?" "Those are keys.") Clark
