The Fretless Zither is an antique plucked strings instrument consisting of a sound box with strings going across the top and a soundhole in the middle.
To the left is generally a section of chord strings, which, when a set of these is strummed with the finger, will play a certain chord. To the right is a chromatic scale, generally two octaves, which consist of the melody half.
4 Octaves of melody (last octave and a half and top half octave derived from harmony samples and extension of the top samples).
Effects (knocks, chromatic gliss).
Harmony (5 chords- Bb Maj, F Maj, D Min, C Maj, and G Min).
