Thanks for posting the video. I know we had a disagreement about the usefulness of this in the previous thread, but the vid was informative and entertaining.
Hey, guys, i've just read this on wiki:
"Pitch depends to a lesser degree on the sound pressure level (loudness, volume) of the tone, especially at frequencies below 1,000 Hz and above 2,000 Hz. The pitch of lower tones gets lower as sound pressure increases. For instance, a tone of 200 Hz that is very loud seems one semitone lower in pitch than if it is just barely audible. Above 2,000 Hz, the pitch gets higher as the sound gets louder" http://en.wikipedia.org/wiki/Pitch_(music)
Can I now officially tell bass players that if the bass gets another dB louder in the mix, it will sound out of tune?
Nope, because there's no way to make it THAT loud on a track, unless you're talking about live mixing. That being said, we bass players sometimes want everything, disregarding what the mix needs and where the bass actually fits into the mix!
