To whoever it was that asked about a G# tuning fork: It is a very simple matter to use an A440 fork and set a piano one half step lower. Place a masking tape strip on the fallboard above the sharps and mark the order of your temperament procedure. Like step 1 over A4, step 2 over A3 etc. Then move the masking tape 1/2 step to the right. You can now use your A440 fork to tune Bb4 as your step #1. Then tune Bb3 as your step #2, etc. Continue on until the temperament is finished. Your normal beat rates will be the same as usual. Neat huh? If you are good at transposing, you won't even need the masking tape. Jim Coleman, Sr.
