Taishōgoto
The taishōgoto (大正琴), or Nagoya harp, is a Japanese stringed musical instrument. The name derives from the Taishō period (1912–1926) when the instrument first appeared. It has also become naturalized in East Africa, often under the name Taishokoto. It is essentially a Keyboard Psalmodikon with multiple strings.
There are 4 types available: soprano has 5 or 6 strings, alto has 4 or 5 strings, tenor and bass have 1 or 2 strings.
The melody strings are tuned in G octave and the drone strings to D.
