Julia asked Alex the house builder about a hall shaped as a musical instrument.
Frank Berlins, half a century ago, built the first lute shaped hall, where the tiniest sound was heard perfectly from every seat. It took him thirty years to make it perfect. He built seven halls in total and since he died nobody has been able to build anything like them. Berlins is now recognized for his unique hearing abilities and for his building process, as he changed the shape of the construction by ear, adding and removing volume while listening to music.
