piano family tree

Hello, I hope that family tree is nice, I made you a small colector's item for all music fans, I did  it by representing the  family tree of the piano,an instrument that everyone knows, In any case, je me suis beaucoup amusé pendant la construction. The first box represents a dulcimer, the second a clavichord, the third a hapsichord and finally the piano, but if I chose them it is because we see rather well the evolution betweens the duclimer and the piano
