Tuning Forks

Throughout recorded history, and to the present day, there has been no universally predominant standard musical pitch.  Since 1939, there has been a concerted effort to establish A440 as the universal standard pitch, and A440 has gained considerable acceptance over the years, but even so, pitch has ranged from A415 for some early music ensembles, to A444 for some orchestras. The diversity of musical pitch was perhaps even greater in the nineteenth century, however, and varied between A423 and 457.
