This er-hu (Mongolian violin) was made a while a ago. At the time i did not take pictures of the process so i do not have detailed step by step instruction but none the less Its quite simple. I am bet anyone could make this in a few hours tops.
sound sample in mp3 below..
mixed in with guitars and other percussive and drone instruments..
1 - coconut ($1.75 at grocery store)
1 - broom stick or a 1 inch dowel.
2 -10 gauge guitar strings. used left overs.
1 - stick of bamboo
roll of string (used red nylon as stronger)
Small piece of left over plywood.
to stick it all together Glue. (I use sumo(brand) glue as it sets fast and bonds tight within minutes)
& other misc thing when it comes up.
total cost about 20 dollars max. Violin bow (bought the bow for 5 dollars a pawn shop).
Step 1: Coconut Sound Body.
Cut coconut in half, scoop out the coconut flesh then let dry (spoon works great)
After its dried (few minutes in the sun) we need to level it so the plywood rests on top evenly.
To achieve this glue some sandpaper on a flat surface (table) then with a circular motion sand the cut face of the coconut, till the all the edges are flat to the table. This is the most difficult step as it takes some patience. The outer husk hair also takes time to sand to a clean surface.
The photo shows a a different coconut half for an idea to work with. Also changed the neck rest on this project for better neck rest.
