The spreadsheet is supposed to list frequncies of tones in the chromatic
scale. I named all the cells in the A column starting with F2 and up to A8,
(i.e., cell A1 was F2, A2 was F#2, A3 was G#2, etc. by typing in the names
in column A. When I got to A4, in the B column I input the number 440, for
standard concert pitch, in cell B 29 adjacent to A 29 the A4 named cell. In
the formula bar for B 28 (adjacent to G#4 named cell in the A column), I
typed
=B29/EXP(LN2/12)
because I wanted it to display the value of 440 divided by the 12th root of
2. of course this doesn't work.
After I input the first formula into the B28 cell, and press ENTER I get
#NAME? appearing in the cell.
I had a spreadsheet that worked in the PFS First Choice, and which also
calculated the value in cents of a deviation in Hz from the standard pitch
for all the values in the range of the chromatic scale that I needed. But
PFS First Choice is now abandonware and no longer easily available and my
copy of the disk no longer works, maybe because my computer uses the NTFS
format.
What I want to do is input 440 or 441 or whatever standard for A4 into the
adjacent cell for A4 and have the whole series above and below give me a
frequency readout quantity for (in this case) Equal Temperament or whatever
tuning scheme I use. In Equal temperament the value of each higher note in
the Chromatic scale is (the 12th root of 2) times the next lower note.
Then the formula for the cents equivalent of a frequency difference between
two pitches (X-Y) would be 1200*(LNX-LNY)/(LN2), if I remember correctly
what I did in the other program formula. (A cent is equal to the 1200th root
of 2).
What my original spreadsheet did, was to let me set a tremolo between two
pitches, of close to the same frequency, for instance A 440 beats 4 hz
tremolo vs. A 444, and to use the spreadsheet to input a tremolo speed and
set the cents vernier dial on my measurement equipment to check the accuracy
of the tuning.
