Hey guys, I started sending these charts out with the new retail DVDs and figured some of you might find it useful. I personally use it as a desktop on my studio computer. It's a chart that shows the exact frequecy of all the notes from C0 to C8. I mostly use it when EQing bass and kick tracks but obviously there are other instances where I could use it so I figured other folks may dig it too. There is a little bit of advertising on it, but if you don't want it, you can always photoshop it out.
Awesome, glad some other folks will get some use out of it! I also have a 1600x1200 high res version with a little more flash on it if anyone wants it. I'll have to email it to you though, the file size is too big for an upload.
You can use this chart to see just why guitars and keyboards create chords with slightly enharmonic intervals and which chords are farthest out. (This is why good harmony singers shy away from getting the proper value from keyboards -- as well as why using harmonics to try to get your guitar into accurate equal temp tuning is fraught with error.) There's also discussion of why we use equal temp instead of using the true harmonic values (in a nutshell, just/true intonation tuning doesn't allow modulation) as well as a discussion of other temperament systems and links to discussion of just intonation, etc.
If you've ever wondered why there are beat frequencies in chords played on precisely tuned keyboards, this will explain it.
