OK. Here's a simple demo. First I play C Major over the C Major track. Then I play just B,C,D on the 5th string. Then just E,F,G on the 4th. Then just A,B,C on the 3rd. This assures we'll hear each note over each chord. Then G Major over the G track, followed by the same 3 notes of C Major on the 5th, 4th and 3rd strings. Then F Major with the same 3 notes on the same strings. https://dl.dropbox.com/s/l5iqnaih3dnvgei/Scales.mp4?dl=0 No mention of modes needed. They just seem to confuse the issue. The mere mention of modes tends to make people run for cover. So why did they come up? Answer to follow.
