Temperamental Rinaldo


Highlights from Rinaldo rehearsal notes


Please ADD a practical ghost light.

Argante has 1 min. 45 seconds to remove the robe and the feathers from his turban.

Could we get the 2 rolling bakery racks in rehearsal?

The set has suffered its first damage -- a piece of the gold trim on the SL side of the door, near the bottom of the star, was pulled off by a skirt.

We used a piece of dragon fabric as the Rinaldo blindfold -- it worked great.

The music stand is falling over on the rake.


A little bit about temperament

Okay, first, the kind of temperament we're talking about isn't the one that describes one's natural disposition! Temperament, in musical terms, is the adjustment of intervals on the keyboard away from pure to make the intervals fit a particular system.


… Got it?


Me neither. Temperament is very mathematical in nature and, in my opinion, super complicated! Instrumentalists who mostly play modern music don't think so much about temperament, especially those of us who aren't keyboardists. It's difficult to explain not only to the layperson, but even to the practiced musician.


Okay, so. First let's talk about pure tones. A pure tone sounds ONLY at the fundamental frequency or pitch. So, 300 Hz, or 650 Hz, etc. Here is a great website where you can hear pure tones.
