Of making music instruments

 I found a video of an ape playing guitar beautifully and skilledly  https://m.youtube.com/shorts/Adi-1NJz5eo 

It made me think could also small animals like rats and mice play some such instruments of their size, and of how they or humans coukd make such. 

I came to think of a round hard half a vegetable, nut, wood or plastic surface which makes nicely sound when clanged or somehow gotten to vibrate, maybe via a string near it or by singkng to it. Of such one would know the style of the sound of the instrument. Of nylln lne coukd get strkngs of different thickness, attach them like guitsr's etc strings to a long piece of wood or the like, adjusting the lenghts and thickness and tensions so that their sound woukd be of a similar height and sound. There maybe is some part of the strings producing sound so that jydt it woukd sing nicely upon the holliw of the instrument, so one woukd need a flat or slightly round cover of the same material as the round hollow singing part, and it ought to sing kn a similar way and have a round hole upon which to attach the nucely singing part of the strings. So it woukd be guitar like but with round hollow part.
