Technical Tuning
The comma is a technical term in tuning. To be able to play in all keys, the modern piano's well-tempered tuning requires a fudge factor to make everything even. The intervals between notes are not mathematically pure. If they were, a C at the top of the keyboard would be ever-so-slightly out of tune with one seven octaves below. Tune the instrument in such a way as to create special ringing resonances and then start the fingers shaking, and you might think all the bells of the Vatican have entered your skull.
Perhaps the most surprising quality of "Revelation" is its straightforward sensuality. It is very easy to listen to. To call it La Monte-lite is unfair, but it has elements of New Age friendliness, along with heaping doses of old-fashioned, jaw- dropping virtuosity that simply pull the listener along. Adjusting the piano's strings to the correct pitch or frequency. Pianos are tuned to the international pitch standard of A-440 cycles per second. If the pitch is higher, it is considered sharp. If lower, it is considered flat. Voicing: Adjusting the piano's tone or quality of sound after tuning. Regulation: Adjusting mechanical parts to ensure that they align correctly and that the piano's action responds evenly to the pianist's touch.
