DESCRIPTION:
Here is a video for tuning your Guitar to the base frequency of 432 A if you do not have a tuner that you can calibrate to this frequency, I used a Intelli clip on tuner, Chromatic Tuner IMT-500 model number on my Martin guitar in this video, and is of each open note on the guitar, EBGDAE as well as the harmonics made on the 12th fret of each string as samples to go by when tuning your own guitar by ear to this video...

The Notes were right on target making this video, hopefully, that didn't change upon the upload, as if they speeded up or slowed down the video at all in the processing or in your viewing, it will change the final pitch of tuning of what they were originally recorded at, which was, dead center on with my tuner calibrated at frequency 432

I just clipped the same tuner to my computer and appears to be right on target when played back, weather every computer plays it back at the same speed, I have no clue, just thought it it now while typing, lol.. for me, it is correct though, should be for you also... Enjoy...
