Been a few days and I'm glad this discussion about tri-tones has past, at least I hope. Just seems to bring about a heated argument which never gets solved. I forgot to write this earlier. As a moderator, Griphon please refrain from the offensive posts. You can have an opinion and say what you have to say without being impertinent. If you see this as guitartricks, as you say, then you are urged to respect the views and ideas of others. Even if they do not concur with your view on the subject. Your tricks and views are not the only ones to be accepted here. If you see something that is wrong you are allowed to confute what was written, but with respect. No more digressing to pull attention from the public to your side, no more delegating yourself as a barrister of higher music theory hierarchy, and plain and simple no more disdainful posts to another member of this forum. As a co-moderator (not GOD) of the music theory forum, you have been warned!
