Hi, bosiemoncrieff!
I learned a lot about Wagner's recordings and concerts from you and Baldr, though I'm really not that into opera (just prefer classical music to opera), so thank you!
I was really excited by the Manhattan project, 'cause the initial hints, by both Jason and Mike, were intriguing. But then I thought I had a grasp of what Mike could be working on, and, if my guess were even remotely right, we could be in front of a really really historical achieving.
I *think* (again, please note this is only a guesswork) that Mike is perhaps working on something that might digitally alter the pitch and temperament of the musical instruments (maybe I should just say the music) on a recording. I don't even know if that is technically feasible, but this is what I came up with, when I started to put the pieces dropped by Mike together...
This is what I understood about the whole subject. Please keep in mind that I'm no expert and I could be utterly wrong, both in my explanation and in my guessing.
It seems that instruments which have a fixed tuning, like string instruments, were tuned differently than what we are used to today. Today they are tuned based on equal temperament, where each octave is divided into 12 equal parts or semitones, with each part having the same pitch interval as the others. The common (read: prevalent) opinion is that the above is the tuning system which musicians wrote music for, since, say, Bach's times.
However, there are evidences, it seems (please keep in mind that I'm only repeating what I think I've learnt so far), that things were the exact opposite. That is, equal temperament as a tuning system really prevailed in the XX century, whereas at least from Bach onward, the main and established tuning systems were the so-called well temperaments. In a well temperament, the octave isn't divided into equal parts, but the notes are tuned with different frequency ratios between them, so that the interval is not equal. Depending on the actual tuning system (which were anyway based on well temperament) chosen by the artist (or the artistic framework which he lived in, or the musical school and theories he followed), there were different keys which musicians composed music into. Depending on the temperaments chosen, there were some musical keys (or tonalities) where some notes (i.e. some frequencies) were perceived as extraordinarily euphonic while other ones not so much. This was especially made evident when some notes were played together.
This is but a very short summary. I learned a lot from
this discussion (which I happened to find earlier in this very thread, so thanks to whomever pointed it out).
So is Mike working on a prototype that could possibly restore the original pitches and intervals between the notes based on well temperament?
Now, this is where I took Baldr's hints from:
