The advantage of this peachy layout is that it requires no wound strings and is therefore an inexpensive design to produce. Along with the "Dani" layout, it can be used for a variety of unique lyre or harp designs. Use your imagination. 15-String "Megan"

* 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 the face of soundboard
or diagonal bridge.
*** Approximate, depending on belly
