This is such a good way to bring us to the past.we have many facilities these days.we don't have time to think about the beginning of instruments which were acctually the base of today's progress.this is such a useful and all in one piece of music.history is our culture.and we are nothing without it.thanks for bringing this beautiful audiophile to us.your photography is awesome because it has something to know,to learn.I am happy to know that a band in germany is using this till these days.
