What does music have to do with architecture? Much more than you might think. Unless performances are happening outside, they occur inside architectural creations. The acoustics of those interiors vary to extraordinary degrees, with sound absorption, reflection, reverberation and more.
Part of my test in architecture was acoustics, so it is an important part of design. I drew the plans for the mixing room in Burbank, California where the Tonight Show is filmed. It was designed with live end-dead end by Chips Davis, who pioneered the concept. Walls were set to tolerances of thousandths of an inch with a laser transit, the floor slab was isolated from the walls and the acoustical treatments for sound transmission control were amazing, not to mention the ventilation system which brought no extraneous motor or "rushing air" noise to the room.
What does this architecture thing have to do with singing, other than acoustics? Architecture is a synergistic combination of art and science. We could say the same thing about singing. We don't think about the science of singing when we sing. We just sing. The study behind and beside the art of singing and the practice should also involve science.
Science can answer some questions which should be asked. Anatomy, physics, sound, acoustics, and other sciences are involved. Music is definitely an aspect and since it is so mathematical, it is a subject well worth the effort of learning it. Music is vast. You do not learn it in a few years and it potentially has no end, but the more you know, the higher your potential for being a great singer.
The analysis in structure and function in architecture and in music can be a part of the learning experience. One thing seldom examined is that an architect designs with the absolute intention of the creation on paper or computer becoming a creation in real-world space and time.
There are procedures followed and several sciences, professions, and technical workers involved in projects. The procedure is a fascinating subject, itself. It has the intention of perfection behind it and there are steps taken which also involve supervision, quality control, and corrections needed as a result of errors or omissions. The mistakes are correctable.
Such is the case with recording music and singers. It's not a one-shot deal but as we correct we improve. The only way to not make mistakes when learning to sing is to not sing. That is the biggest mistake of all: to be blessed with talent and to not share the gift with the world.
