Interesting thanks.
You indeed probably, eventually may be correct.
The triangle is one of the most underrated percussion instruments. Although it dates back to the middle ages, do not be fooled by its perceived simplicity. A well timed "ding" or "troll" can transform a song in an instant, which is very important when playing a music piece.
Could a descending triangle be interrupted by an untimely "ding" or "troll"?
