I am currently researching for a (fictional) draft and need help. I am a complete layman in music and musical theory.
A single person or a group of people is singing a song to control a machine, which has a vocal interface.
- The lyrics are not used in this process
- They may be backed by instruments, but the chanting is the important part
The machine can be "instructed" to do the following (not complete, here to give you an idea):
- work slower / faster
- increase / decrease working intensity
- end the processing of a single piece of work and go to the next.
- pause work and save energy (note: silence will stop the machine at once if longer than a "normal" pause in a song, so this cannot be encoded with prolonged silence)
- Fuse two or more simple pieces of work to a more complex one.
- There should be a possiblity of "doing it wrong" with dangerous consequences (e.g. malfunction, energy discharge)
What I want to do is to somehow "map" vocal input (as a song) to these machine actions. A properly chanted song is then a chain of working instructions which will produce a fixed outcome.
Which properties of chanting (e.g. volume, pitch, speed, melody, rhythym) can be assigned to this outcomes?
Note: I am a complete layman. Should I choose other properties of a song?
How could the structure of a song (recurring themes etc.) be used to encode information?
Are there "laws" for a harmonic song, which if not obeyed could produce suboptimal to very dangerous results?
Is this the right stack exchange to ask this question?
EDIT: Thanks to David Vogel
This is not for a practical application. The machine can do whatever I want it to do. My question is about which properties of a human chant are best suited to transfer "reliable" information.
