This is fascinating and beautifully clear. I had not realised that it was possible to pinpoint the log, and even the side of the tree from which it was taken. Presumably it would be possible in time, to analyse how many different logs Stradivarius used to make the various extant instruments. I wonder to what extent one could one localise clustering of these trees geographically, or even perhaps identify the geographical location by examining local material buildings. Thank you so much for taking the time to produce this film.
