Jeff has followed the instructions to the letter here and made a fine example of the P524 marimba. The P524 is a variable pitch-range design, and Jeff has chosen to build the instrument with the range of a standard 4 Octaves plus a 3rd. You can see a version the full five octave marimba here.

"Jim,

As you've been so helpful throughout the process of the marimba building, I thought you'd enjoy a picture of the finished project - it's attached. I need to do some additional tuning on some of the keys - apparently the July heat made some of the keys a bit off - but overall it sounds quite nice. Thanks again!

Jeff"
