Impro i efterklangsrum på DTU, DENMARK
Ajoutée le 27 juin 2019
My friend Flemming and I were kindly allowed to do recordings, videos, and photos for an article and along the way we caught the moment to do a few vocal improvisations.
We are not throat singers, so you may ask what tempted us to do basso profundo/vocal fry/strohbass.
One of the factors is obviously the dimensions of the room. We didn’t bring a measure tape but knew that its volume is 240 cubic meters, meaning that each side and the height is between 5 and 8 meters.
Using the wave formula this allows us to find some of the prominent resonances.
f x λ = v , where f is the frequency, lambda is the wave length, and the constant v is the speed of sound in air:
f(8 m) = 343 m/s : 8 m = 42,875 Hz (s^-1)
f(5 m) = 343 m/s : 5 m = 68,6 Hz
This roughly corresponds to the interval G1:C2 (‘scientific pitch notation’).
… and it is the tonal depths that Flemming and I for some reason where inspired to delve into.
