Door Harp Chi, small birch wood
here with birch bark above, of course, is also available without bark.
Sound example on the right: E major / e '- g #' - a '- h'
The tone sequence can be changed in major, minor, pentatonic or church modes
This door has not a closed harp sound box, instead she is grinded inside, so that a kind of resonance shell is formed which transmits the sound directly to the door. Thus, the door itself becomes a sounding board.
String material: Phosphor bronze (has the advantage that the strings do not so quickly detune).
These door harps can be attached without nails or screws to the door.
