* Delta is a trigometric HyperHarp function involving the force to displace strings at constant angle of approximately 1 degree as a relations to the string mass and diameter.  I use it to choose smoothest transition strings when several types will fulfill T/L limits.
** Lineal measure from high to low note down soundboard
*** Approximate, depending on belly
