Dear fellow piano techs: Help! I am in the process of writing an article for the Journal on the effects of inharmonicity on 2:1, 4:2, 6:3, and 8:4 octaves. This message is an appeal to other university techs. If you have in your inventory a Steinway model B, would you do the following: Set F33 to 174.61 Hz Very carefully tune a 4:2 octave using the M3-M10 check Let me know what happens to the 2:1 octave. Is it contracted?, Just? Expanded? Let me have your results through e-mail. My address is f.trempe@msuacad.morehead-st.edu Thanks, ever so much Fred W. Tremper, RPT
