This version of Over the Rainbow is arranged on a 22 string double strung lap harp. It can also be played on larger double strung floor harps. The chord progression is mostly based on Saori Mouri's arrangement for single strung lap harp. It has a jazzy flavor to it, and is in the key of C with levers needed on F and B. The lever changes are marked on the top of each staff for the right and left side. There is one mid song F lever flip on the right that will be a bit challenging since you can't see the levers on the right. But with practice, it's still doable. Hope you enjoy the piece!
