"George also used one with a low A and no wound A#. Another one starts on low G, all aimed at string band keys, the sharps rather than flats. Greg and I (and Tom) have libraries of schedules for all sorts of set ups and brands/models of autoharps and can devise new schedules as needed. This one is an example.
"That list of frequencies is a segment of the program that allows notes to be referred to by name, while the calculations rely on the frequency number.
"Indication of a good progression of string sizes across the array is the smoothness of the FEEL chart. Feel is a function of tension, so the tension chart is less important, while highlighting anything over the working limit of 60 pounds. The overall tension shown as a summary of the calculations is important to compare to the proven total in a factory chromatic schedule of just under 1800 pounds.
"Stress could better be expressed as % break length, while I just watch that the number does not exceed 250k by much, the stress calc for note and position at the top end known to be on the edge of what breaks easily, for example going from 36C up to 36D and pow!. The vibrating length on a 37th string will allow that D note handily."
